Have a Ryobi Battery That Won’t Charge? You Can Fix That.
Lithium ion batteries are a wondrous invention that are lightweight and long lasting. But it’s infuriating when the battery won’t recharge. You stick the battery in the charger and. nothing. Guess what? You can fix these batteries that appear to be completely dead. Read on.
This post is NOT sponsored by Ryobi. They do not approve of or endorse this method for fixing a Ryobi battery. AT all.
One of two things are going to happen as you read this post. You will either unfollow me due to my pathological boringness or. you will propose marriage. So get ready to act accordingly.
If you have any sort of cordless power tool, but especially one powered by a Ryobi 18V battery, you have no doubt encountered the dreaded flashing red charger light.
And if you haven’t. you will.
It inevitably goes like this. you run to the basement to grab your cordless drill because after 10 years of thinking about it, you’re finally going to build that 4 level, Tudor style treehouse with kitchenette.
Or you’re going to hang a picture.
Either way you put your battery in the charger and all you get is a flashing red light, which according to the label on the charger means your battery is defective. It isn’t just dead. It’s defective.
I’m here to tell you you it isn’t. You probably left it in the charger too long which drains the battery.
Your battery is fine. It just needs a little boost.
You Can Fix a Rechargeable Battery That Won’t Take a Charge.
You heard me right. You do NOT have to buy a new 50 battery. You do not have to call the company and swear at them because this stupid defective battery is only 2 weeks old. (although by all means feel free to do so) You do not have to wait until they ship you a replacement battery to finish your project. You can get that battery up and working in about 5 minutes.
NOTE: First try pulse charging.
Pulse charge your battery by plugging and unplugging your charger (with the battery in it) for 10 seconds. Try this a few times. If it doesn’t correct the problem, continue on with this tutorial.
How to Fix an 18V Battery
What You Need
- A multimeter. (this is actually optional but helpful. if you don’t have one don’t worry, you can still fix your battery)
Note: If you aren’t used to doing this sort of thing, or using things like a multimeter this is going to seem crazy and hard and way out of your DIY league. It isn’t.
Step 1. Cut the end off of your AC adapter. That’s right. Just cut it off. It’s for a 10 year old cell phone, you’re never going to use it again anyway. It’s frankly kind of weird that you saved it to begin with.
Step 2. Separate and strip off 1 of each wire. You have just made booster cables! Good for you.
Black wire = negative Striped or solid white wire = positive
IT IS VERY IMPORTANT TO NOT MIX THE TWO UP.
Step 3. Remove the screws holding the battery together.
For Ryobi batteries it’s a star shaped screw head like the one below.
A few years ago I bought a kit of small screwdriver heads from Amazon that has every small, weird, head you’d ever need.
There’s a hidden screw under a piece of plastic. You need to pry the plastic off to get at the screw underneath. I used a very thin screwdriver to pry it off.
Step 4. Pull the top off of the battery case.
Step 5. Remove the 2 plastic side pieces. They’re the things you press in to remove your battery from your drill.
Step 6. Lift the battery pack out.
Step 7. Set the Multimeter to read volts. For testing an 18 volt battery choose the 20 volts setting. This will give you the most accurate reading. (If you don’t have a multimeter skip to Step 9 and hope for the best)
Volts are symbolized by a V with one or two straight lines over it on a multimeter so it’s that section of the multimeter that you use. The section under the V with the straight line(s). Not the squiggly line. The straight line.
Step 8. Touching the red probe to the positive (red) terminal and the black probe to the negative (black) terminal, read the voltage shown on the multimeter. In my case the battery was carrying a charge of 0.06 volts. Which is almost nothing, but not completely nothing.
Step 9. Plug your AC adapter in and using the wires, boost your dead battery. Just touch the black wire to the negative terminal (the one with the black wire going to it) and the white wire (or striped wire) to the positive terminal (the one with the red wire going to it). Do this on and off for approximately a minute.
Apparently lithium ion batteries should be pulse charged. Which means you hold your wires down for 15 seconds or so, then release them. Then hold them down again. Over and over.
DOUBLE CHECK THAT YOU ARE TOUCHING POSITIVE TO POSITIVE AND NEGATIVE TO NEGATIVE.
This is the best battery powered chainsaw!
Step 10. Test your the voltage on your battery pack again. It should be higher than it was before boosting. (Again, if you don’t have a multimeter don’t worry about this. you’ll just have to press on without one)
Mine went from 0.06 volts to 7.58 volts after a minute long boosting session.
Step 11. Put the plastic cover back on the battery pack (just the part that goes into the charger) and set your battery on the charger to see if it will take a charge.
If you still only get a red flashing light and the battery won’t charge, boost the battery some more. I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts.
Just keep repeating the pulse boosting and testing the battery until it will finally be recognized by the charger and you get the green light.
To those of you who found this subject matter to be on par with spending 3 hours in a waiting room, sorry ’bout that.
For the rest of you? I know exactly how you feel. I felt the same way. Let me know exactly how elated you were after you brought your first battery back to life in the Комментарии и мнения владельцев section.
Here’s a 3 minute tutorial video showing me as I fix my own battery.
How to Fix a Ryobi 18v Rechargeable Battery
You have an almost brand new Ryobi battery that the charger won’t recognize and won’t charge. Here’s how to fix that.
NOTE: Before doing all this, first try to pulse charge your battery by plugging and unplugging your charger (with the battery in it) for 10 seconds. Try this a few times. If it doesn’t correct the problem, continue on with this tutorial.
Cut the end off of your AC adapter. That’s right. Just cut it off. It’s for a 10 year old cell phone, you’re never going to use it again anyway. It’s frankly kind of weird that you saved it to begin with.

Do this on and off for approximately a minute. DOUBLE CHECK THAT YOU ARE TOUCHING POSITIVE TO POSITIVE AND NEGATIVE TO NEGATIVE.
Test your the voltage on your battery pack again. It should be higher than it was before boosting. IF IT IS NOT, THEN STOP. YOUR CELL COULD BE DAMAGED AND CONTINUING COULD BE DANGEROUS.
Put the plastic cover back on the battery pack (just the part that goes into the charger) and set your battery on the charger to see if it will take a charge. If you still only get a red flashing light and the battery won’t charge, boost the battery some more. I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts.
Repeat the pulse boosting and testing the battery until it will finally be recognized by the charger and you get the green light.
Best Battery Chainsaw Reviews 2023 | Best Cordless Chainsaws
Boy, did we open a can of worms when we started searching and testing to determine the best battery-powered chainsaw models. Not that long ago, there weren’t that many cordless chainsaws, and even fewer had high enough performance to warrant replacing gas saws.
Fast forward to today and cordless chainsaws meet and even exceed gas performance all the way up to 20-inch models. Most recently, saws hit the market that can replace gas in the farm and ranch class. Our team of experts got together to hash out which cordless chainsaws are the best in 2023.
Want even more chainsaw recommendations? Check out our Best Chainsaw main page for options including gas, battery, and electric models!
Best Battery-Powered Chainsaw for Pros
STIHL 36V Brushless 20-Inch Chainsaw MSA 300 C-O
Pros have more options than ever before and that includes 20-inch cordless chainsaws. Of the ones available, Sithl is likely the most anticipated battery-powered chainsaw for professionals in a tight battle (DeWALT and Greenworks Commercial also have 20-inch models). Aside from hitting the 20-inch mark, it has the power to replace farm and ranch class gas saws and, of course, is backed by STIHL’s dealer service network.
The saw has 3 performance settings so you have options when you want to prioritize runtime over power. It has an LED screen that displays power status, mode, chain brake position, and has a low oil alert. For those of you managing inventory, it’s also connected 2 A compatible.
STIHL introduced the AP 500 S battery along with the saw, giving the MSA 300 C-O an advanced power source to pull its high performance from.
Price: 789.99 bare (may vary)
Most Powerful Professional Battery-Powered Chainsaw
Greenworks Commercial 82-Volt 20-Inch Chainsaw 82CS34
In late 2021 at GIE, DeWALT, Geenworks Commercial, and STIHL all announced new 20-inch battery-powered chainsaws with the power to take on the farm and ranch class. All three also claimed to have the most powerful and as the dust settled, Greenworks Commercial’s had the highest-rated power.
In addition to having higher power, it’s also a couple of hundred dollars less than Sithl’s 20-inch model. It gets into a range that even homeowners with large properties to maintain might be tempted to step up.
As a side note, Greenworks also has a 20-inch chainsaw now available for its 60V residential lineup.
Price: 549.99 bare, 599.99 with 4.0Ah battery and charger
Best Battery Top Handle Chainsaw
Husqvarna 40V Top-Handle Chainsaw T540i XP
By our measure, Husqvarna’s 540i XP is the best cordless top-handle chainsaw currently available. Though quite not as powerful as the Greenworks Commercial 82V yet stronger than Echo’s 56V, its balance of 40cc power, weight, and 12 – 16-inch bar options make it an excellent choice for arborists.
While Echo takes the cake as the lightest professional choice, Husqvarna does have the option to use a backpack battery and shift some of the battery weight off of the saw. It’s not terribly practical when you’re climbing, but can be handy for ground-level work.
Price: 629.00 – 649.00 bare, 1049.00 – 1069.00 kit depending on bar length
Best Battery Pole Saw
Makita 40V max XGT Telescoping Pole Saw GAU02
When it comes to the best battery pole saw, multi-head systems are an excellent platform. However, most professional crews prefer dedicated tools to attachment systems. If that sounds like you, check out Makita’s GAU02. It’s a 9- to 13-foot telescoping system (full length, not just reach) that reaches significantly higher than most of its competition.
Its performance is impressive. It uses a single 40V max battery with its 10-inch bar to cut at speeds up to 3940 fpm (20.0 meters per second). In terms of overall power, it’s the equivalent of a 35cc gas engine. In fact, Makita’s internal testing showed 30% faster cutting compared to a 36cc gas model.
This model doesn’t include the torque boost mode that was in the 18V X2 LXT model we recommended last year. However, with the boost in overall power, it doesn’t really need it.
Price: 554.00 bare, 769.00 with a 4.0Ah battery and charger
Looking for a battery-powered pole saw for home use? Take a closer look at EGO’s 56V telescoping pole saw that has a total reach up to 16 feet, has a carbon fiber shaft, and sports an LED cutline indicator.
Best Cordless Chainsaw for Home Use
Greenworks 60V Pro Brushless 2026202
n choosing the best battery chainsaw for home use, we didn’t want to sacrifice the power we enjoy from our professional saws. While there are a lot of options available, we tend to get the best balance of performance and weight in the 60V class.
Greenworks brought a major upgrade to its 60V line with a 20-inch chainsaw. While it’s not quite as strong as the 3.4kW Commercial model, it’s still packing a strong 3.0kW of power. To put that in perspective, Greenworks’ internal testing had it cutting faster than a 60cc gas chainsaw. It also outputs 20% more torque. Not only is Greenworks the first to get a 20-inch battery-powered chainsaw to consumers, but it also has legitimate performance to back it up.
The downside of being the best is that it costs more—around 499.99 for the kit. This is for folks that need or want the highest performance available from a residential chainsaw.
Price: 499.99 with an 8.0Ah battery and charger
Best Small Battery-Powered Chainsaw
Choosing the best small cordless chainsaw isn’t just a matter of choosing something lightweight with a 10- or 12-inch bar anymore. The introduction of battery pruners with a 4- to 8- inch bar and chain ups the ante. So we picked one of each for you.
Ryobi 18V HP Brushless Whisper Series 12-Inch Chainsaw P2570
We value performance over price, so our top pick as the best small battery-powered chainsaw is the Ryobi P2750. It’s part of the 18V One HP Brushless line that delivers higher performance than its brushed counterparts. It’s also part of Ryobi’s Whisper Series. That means it operates at lower noise levels than other models and makes for a better overall user experience.
The small size also keeps things on the lightweight side of the scale. With a 6.0Ah battery, this 12-inch chainsaw weighs just 8.7 pounds.
Price: 229.00 bare, 249.00 kit with 6.0Ah battery and charger
Best Battery Pruner
Milwaukee M18 Fuel Hatchet 8-inch Pruning Saw 3004
It’s almost unfair to call the Milwaukee M18 Fuel Hatchet a pruner. While it has the general form factor of other popular mini-chainsaw pruners that have hit the market over the last few years, it’s on a completely different performance level.
While it’s certainly useful as a pruner when manual pruners or hedge trimmers can’t cut it, landscaping crews can also use it for limbing duties on the ground or working at height. In many ways, the Hatchet bridges the gap between pruners and top-handle chainsaws.
Price: 279.00 bare, 528.00 with an 8.0Ah battery High Output battery and charger, 579.00 with a 12.0Ah High Output battery and charger
Best Cordless Chainsaw for the Money
EGO 56V 16-Inch Battery-Powered Chainsaw CS1611
EGO already had a solid 16-inch chainsaw on the market, but they released a new one in 2022 that accomplished a couple of things. First, it upped the performance to compete with and even beat gas saws in the 40cc class. With a couple of kit options all under 300.00, it also earns our pick as the best value battery-powred chainsaw currently available. If getting the most bang for your buck is your highest priority, this is your chainsaw.
Price: 239.00 bare (CS1610), 279.00 with a 2.5Ah battery and charger(CS1611), 299.00 with a 4.0Ah battery and charger (CS1613)
Best Budget Battery-Powered Chainsaw
Skil PWRCore 40 14-Inch Cordless Chainsaw CS4555-10
Just because you’re on a sub-200 budget doesn’t mean you can’t get a quality brushless chainsaw. Skil’s PWRCore 40 system includes a 14-inch brushless chainsaw that finds an excellent balance of performance, design, and price.
We tested this saw cutting oak and it did an excellent job of confidently melting through branches up to 12 inches thick. With auto-oiling and a tool-free chain adjustment system, it’s very easy to use as well. Best of all, the kit is just 199.99.
Price: 199.99 with 2.5Ah battery and charger

Recommendations from Brands We Trust
Best DeWALT Cordless Chainsaw – 60V Max Brushless DCCS677
Without a doubt, DeWALT’s 60V Max 20-inch cordless chainsaw (DCCS677) is the best model in Yellow’s lineup. As one of three professional battery-powered 20-inch chainsaws targetting the farm and ranch class, it’s in a very elite class and it happens to be the least expensive of them.
In designing the saw, DeWALT’s development team used the largest brushless motor in any tool they have, period. Along with a list of features that verify its professional pedigree, it’s also the first DeWALT chainsaw to come with a case.
Price: 379.00 bare, 479.00 with a 4.0Ah battery and charger, 549.00 with a 5.0Ah battery and charger
Best Echo Cordless Chainsaw – 56V Brushless DCS-2500T
Echo is moving away from its original 58V cordless line to a new 56V Force system (the two systems are not compatible). Along with the initial launch, there are two chainsaw offerings: a homeowner-grade 18-inch model and a Pro-focused 12-inch top handle.
The top handle is our choice as the best Echo battery-powered chainsaw. As part of the X-Series, the DCS-2500T oozes professional design. It starts with a muscular brushless motor and builds out the drop protection (including a quickdraw harness ring) you expect from a professional gas top handle saw. Plus, it’s very lightweight at just 7.3 pounds with the battery. It’s definitely not your least expensive top-handle option, but it is designed with the demands of professional arborists in mind.
Price: 479.99 bare, 569.99 with a 2.5Ah battery and charger
Best EGO Battery-Powered Chainsaw – 56V 18-inch Brushless CS1800
Moving to an 18-inch bar, the EGO CS1800 is still on the top of the charts for homeowners even though the brand hasn’t moved up to the 20-inch class (yet). It has excellent power and there’s plenty of runtime with available batteries up to 10.0Ah (a 5.0Ah pack comes in the kit).
In addition to its performance, EGO’s auto-tensioning system makes it super-easy to adjust the chain tension and access the bar and chain without the use of additional tools. There’s even an LED to help with post-storm cleanup when the power’s out and you can’t wait for sunrise.
While there are stronger residential saws available, the ease of use, size, performance, and price all come together in a very approachable manner for folks that aren’t used to professional models.
Price: 279.00 bare, 369.00 with a 5.0Ah battery and charger, 579.00 with two 5.0Ah batteries and charger
Best HART Battery-Powered Chainsaw – 40V Brushless Supercharge HLCS041VNM
HART is stepping up its chainsaw game this year by moving into the 18-inch class. Part of a new line of 40V Supercharge products, this brushless chainsaw pushes performance higher enough to compete with gas models in the 40cc range. Along with a quality feature set, it also comes with a handy case for storage and transport that holds both the saw and the 6.0Ah battery that comes in the kit.
Keep your eyes open for this saw to show up at Walmart by the end of February 2023.
Best Husqvarna Cordless Chainsaw – 40V Brushless Power Axe 350i
With Husqvarna’s deep heritage in chainsaw manufacturing, you may be surprised that the Power Axe 350i is its first 18-inch cordless chainsaw. This Lowe’s-exclusive model features a brushless motor that does most of its work at an efficient 9.4 m/s chainsaw speed and has a boost feature that kicks it up to 11.7 m/s for getting through tougher cuts.
This residential-focused chainsaw balances that performance with an easy-to-use design. It’s also light for its size and has completely tool-free chain tensioning.
Price: 279.99 bare, 449.99 with a 7.5Ah battery and charger
Best Makita Cordless Chainsaw – 40V max XGT GCU04
We’ve been using Makita’s 18V and 18V X2 chainsaws for years. However, it’s the 40V max XGT line that has the best options for Team Teal. The GCU04 steps up with 42cc gas equivalent power thanks to its brushless motor. It sports an 18-inch bar with chain speeds up to 5020 fpm (25.5 m/s).
This model has dual bar studs with captured nuts. If you prefer tool-free chainsaw tensioning, you can get the same performance with that feature in the GCU06.
Price: 429.99 bare, 599.99 with a 5.0Ah battery and Rapid charger
Best Milwaukee Cordless Chainsaw- M18 Fuel 2727
Milwaukee had one of the first really great cordless chainsaws and the M18 Fuel 2727 is still an excellent choice. It sports a brushless motor that runs its 16-inch bar and chain to levels that exceed 40cc gas power. It has a quality build with metal bucking spikes and dual captured bar nuts.
Even though other brands have pushed the power boundary forward, we still highly recommend this saw. Now that Milwaukee has raised the bar with its self-propelled lawn mower, there are whispers beginning to ask if there’s a new high-performance chainsaw in the works for later this year.
Price: 329.00 bare, 499.00 with 12.0Ah battery and charger (also available with a 14-inch bar for 319.00)
Best Ridgid Cordless Chainsaw – 18V Brushless R01101
Hey—we’re talking about a Ridgid cordless chainsaw for the first time! Ridgid is launching its first OPE products in 2023 and a 12-inch chainsaw is on the menu. While it’s on the smaller side, the saw’s 18V brushless motor is capable of 10 m/s chain speeds. It’s a good choice if you’re looking for something lightweight.
Like many Ridgid power tools, the chainsaw is eligible for the Lifetime Service Agreement.
Note: Look for Ridgid’s chainsaw to be available beginning March 1, 2023.
Price: 189.00 bare, 269.00 kit with a 6.0Ah Max Output battery and charger
Best Ryobi Cordless Chainsaw – 40V HP Brushless RY405110VNM
Ryobi’s launch of HP Brushless tools has been impressive. The 40V HP Brushless 18-inch chainsaw is a fantastic example as one of only two 20-inch models currently available on the residential scene. With cutting performance that can replace a 50 cc gas engine, it’s far ahead of Ryobi’s other models and enters the Farm and Ranch class.
With metal bucking spikes, dual bar studs, and an adjustable oil flow, Ryobi’s flagship cordless chainsaw acts more like a professional model than an occasional-use homeowner one.
Price: 289.00 bare, 379.00 with a 5.0Ah battery and charger
Best Skil Battery-Powered Chainsaw – PWRCore 40 Brushless CS4555-10
As we mentioned above, Skil’s 14-inch brushless chainsaw is the way to go if you’re looking for a budget saw that still does a great job. You get the performance of a brushless motor, confident cutting, and a price tag under 200. While it doesn’t have the same power and capacity as the larger saws, it does share many of the same features and costs significantly less.
Price: 199.99 with 2.5Ah battery and charger
Best STIHL Cordless Chainsaw – 36V Brushless MSA 220 TC-O
As our top choice overall, STIHL’s MSA 300 C-O is the best the brand has as well. It’s not the only class STIHL is in. Pros may want to consider supplementing that model with the MSA 220 TC-O. This top-handle chainsaw has a brushless motor. It’s the strongest cordless top-handle in STIHL’s cordless lineup and configures with either a 12- or 14-inch bar.
At 10 pounds with the 14-inch bar and AP 300 battery, it’s not the lightest top-handle model on our list. However, it’s still a very manageable weight and, of course, you’re backed by Sithl’s dealer and service network.
Price: 589.99 bare with 12-inch bar (may vary)
Best Battery Chainsaw Buying Guide | What We Look For
Performance is King
Thanks to advanced brushless motors, electronics, and batteries, voltage no longer tells the entire story. However, cutting speed with the torque to get through thick hardwood species is the number one priority for us.
Best Chainsaws 2023 [don’t buy one before watching this]
Runtime is (Sort of) a Big Deal
Ideally, a battery-powered chainsaw balances cutting speed and power with runtime. Larger batteries are certainly helping. Advancements in battery technology are as well. Denser cells with more robust connections are able to more efficiently transfer energy from the battery to the chain. This gives you higher performance without a drop in runtime that makes the saw irrelevant.
The other side of the conversation involves Rapid chargers. Most brands offer them now and several include them as a standard part of the kit. With today’s cordless technology, two batteries and a Rapid charger can be enough to keep you running continuously all day.
Most chainsaws are similar in form and share all of the same basic operational features. Where the best cordless chainsaws differ in form is primarily in their switches and triggers.
All of the saws have a UL or similar test lab certification on them, but they’re not all the same. In use, some of the saws in our test have more defined two-step triggers. Others easily activate using a single grasp around their lockout button and trigger. At the end of the day, we expect our chainsaws to keep us from accidentally activating the motor. All of our recommendations meet that requirement. From there, it’s just a matter of the feel or function you prefer.
The true two-step lockouts aren’t difficult to operate in normal conditions. In odd positions, such as reaching around a tree while limbing, sometimes the mechanical lockouts can be tricky to slide.
For select cordless chainsaws, the first of two (or sometimes three) stages of starting is an electronic power button.
Some electronic switch saws can be run with a single grab once powered on. You just have to be mindful of the auto timeout feature. It can be frustrating the pull the trigger to no effect when you thought the saw was ready.
Ease of Adjustment
Chainsaw bars need to be adjusted nearly every time you use the saw. A new chain stretches out pretty quickly. You need to snug it up at least a few times as it breaks in.
If your chain gets tight rather suddenly, it usually means the bar is not getting oil. Don’t loosen it until you make sure the saw is oiling properly.
Pro Tip: Get into the habit of loosening your chain at the end of the day. Cold weather can cause it to tighten as it cools and damage parts.
A saw’s bar will be designed for either tool-free adjustment or will require a screwdriver-wrench combination tool called—yep, you guessed it—a scrench. Tool-free adjustment is the quickest and easiest with plastic knobs and/or dials built into the saw. They loosen the bar, move the bar forward or back to properly tension the chain, and lock the bar down tight again.
Dual Studs vs Tool-free Adjusters
Saws with tool-free adjusters use a single stud to attach the bar to the saw, but manual adjusting models typically have two mounting studs (sometimes one on small or top-handle models). Some old-school users view dual studs as an indication that the saw is geared toward professionals, but we don’t think that’s a hard, fast rule. Not for modest-sized saws anyway. However, the biggest and strongest chainsaws made all have dual stud bar mounts.
Pro Tip: Be sure to snug the nuts evenly because torquing down on only one can loosen the other.
Lost bar nuts are a frequent occurrence during regular use in the field. To prevent this, some saws have the added feature of captive nuts that won’t come all the way off the cover no matter how much you spin them.
Pro Tip: Keep a spare nut on hand if the ones on your saw aren’t captuve—it’s not unusual to lose one in the field!
To keep your adjustment tool close at hand, look for models that have storage slots built into the saws.
Your preferences may vary, but we can appreciate both adjustment methods. We like the speed and convenience of tool-free adjustments for small saws. For big saws, we feel more confident securing the business end of these powerful tools down with a wrench.
It’s not a deal-breaker either way for the saws in our test unless the mechanism itself is flawed. The best battery-powered chainsaw for you is the one that instills a sense of both confidence and convenience.
Bars and Chains
Most chainsaw brands don’t try to reinvent the wheel by making their own bars and chains. Instead, many use quality Oregon components, though STIHL makes their own bars and chains. Most cordless chainsaws use 3/8-in. pitch, 0.043-in. gauge chains while stronger models are moving up to 0.050-in. gauge.
Bar and chain oil is the lifeblood of a chainsaw as the saw cannot run without it for very long. Most saws oil readily, but we occasionally run across models that have issues after a while. If a saw oiled well out of the box, it usually just needs a good cleaning to unclog it.
Most battery-powered chainsaws have translucent Windows that let you check if there’s oil in the tank, and most let you estimate the level pretty well. If yours has a small window or none at all, be sure to stop and check the oil level frequently. About every hour of working time or anytime you notice a change in performance is a good rule of thumb.
The ease of filling the oil reservoir is a noteworthy convenience factor when considering the best battery-powered chainsaw. We don’t like having oily fingers, so being able to fill the tank while leaving our work gloves on is our preference. Look for oil caps with lugs that are easy to turn with gloves on and/or flip-up tabs that provide an even better grip.
Chainsaws often leak oil while sitting because daily heating and cooling shrinks and expands a plastic tank like a rudimentary pump. Some saws are messier than others.
Wherever you store your saw, put a piece of cardboard underneath it to collect any oil. You can switch it out as needed and whenever an Amazon order arrives.
Be careful when filling your chainsaw. Some have a large section of the cap that goes inside the tank and displaces a surprising amount of oil when you fill it anywhere close to the top. Wiping gooey oil off a chainsaw is an annoying waste of time.
Another cause of spills is an oil tank with a filler neck that is too narrow. Bar and chain oil is thick and tacky. It can pour like molasses in the cold, so it easily “piles up” and overflows in a narrow neck.
Pro Tip: Only poke a small hole in the foil of your oil container or use a (clean) syrup bottle to dispense oil into your chainsaw’s reservoir.
Providing another challenge, plastic filters at the inlet of its tank can constrict the diameter.
Caps that cross-thread easily can also make the oil-fill process more of a chore.
Environmental Sidetrack: Try Biodegradable Bar and Chain Oil
The other part of this cleaner, greener, lithium-ion-powered story is you can pair your battery chainsaw with a biodegradable bar and chain oil made of vegetable-based ingredients, such as STIHL Bio Plus. Those barrels of useful wood waste also contain a few gallons of oil from the saws.
Aside from having to landfill all of your petroleum-preserved sawdust, it’s just good practice to minimize your exposure to petroleum oil on your skin, clothing, and the atomized portion that you breathe in.
Back on Track… Bucking Spikes
For pushing a saw through wood more efficiently, chainsaws come fitted with bucking spikes. You may also hear these called bumper spikes, felling spikes, or dogs. These spikes sit against the body of the saw alongside the bar. They anchor the saw in place while you pivot the bar through a cut.
The spikes allow you to apply a lifting motion of the rear hand instead of pushing downward. Holding the saw tight to the wood, the motor can exert its maximum pulling power. This saves you from some of the cutting vibrations common when holding a saw away from your work.
Our battery-powered saws all have some semblance of spikes. Most aren’t as long or as sharp as those on large gas saws. However, actual steel spikes are becoming more common. We prefer those to the simple plastic ridges on other models.
Pro Tip: Applying leverage with spikes adds control, but go easy and listen to the pitch of the motor. You can overload battery chainsaws with too much pressure, and the weaker models stall easily.
While it’s true that the comfort and feel of a tool are largely subjective, it’s also true that some designs work better than others. Most Pros and experienced homeowners can immediately tell.
For the best battery-powered chainsaw, a balanced feel in your hands and the ability to cut straight without introducing a twisting motion to overcome are both important ergonomic factors.
Holding a saw with your left hand on the front handle in front of you should have the saw balancing fairly flat. Being a bit front-heavy is okay, but a rear-heavy saw lifts the cutting end of the saw up towards you and requires more effort and vigilance to use and carry safely.
Determining a good feel for felling cuts while holding the chainsaw sideways is more about the comfort of applying force to the front and rear handles as you grasp it from the side, and also the ease of operating the trigger while sideways.
In general, chainsaws with thicker handles are more comfortable to grasp in use because have more surface contact and soften that contact with your hand. Of course, rubber handle surfaces help too, not only for padding but also for the increased grip they provide.
Most cordless chainsaw triggers are large enough for two fingers to fit on them. Some have an extra-long trigger with more room to vary your grip stance for comfort. The best feeling triggers retract flush with the handle instead of leaving a raised bump your fingers have to push against.
The dry weight of the best battery chainsaws can swell to well over 15 pounds. Experience shows that a saw’s weight is less important than proper balance overall as you only feel the full weight when you’re NOT cutting.
But carrying around and positioning a heavy saw can certainly be more taxing over a long workday. The catch with these saws is that the batteries are a major part of the weight. So the stronger, longer-lasting saws with high-capacity battery packs and longer bars that we prefer end up being the heaviest.
While we do the majority of our testing with the kitted batteries, it’s worth looking at the full range a manufacturer has available for your cordless chainsaw. If you end up investing in the entire lineup, you’ll likely want to consider the biggest batteries you can buy for it to get all of your lawn chores done efficiently.
You might also want a lower-capacity battery to shave some weight when you don’t have a lot of work to complete.
Higher voltage means more power, right? There’s certainly an argument for that, but it doesn’t tell the whole story.
Power is measured in watts and that comes from multiplying the voltage times the current. You can make a 36V chainsaw with the same power as a 56V model. The lower voltage simply has to produce more amps (current) to get there.
That’s why you see chainsaws with 40cc gas performance at 18V, 36V, and 60V. It’s all about the combination of volts and amps.
Another thing that is interesting to note is the discrepancy between the amp-hour and watt-hour ratings on some of the batteries in our tests for their given voltage. We’ve covered the subject of battery voltage, storage capacity, and current output many times. To review simply:
Volts x Amp Hours = Watt Hours
It’s the same basic equation we use for power, just applied to energy storage instead of output. It’s an easy way to compare the available energy of one battery to another when they have different voltages.
We’re increasingly finding that manufacturers—perhaps to simplify things for consumers—are rounding amp-hours. Some calculate their watt-hours with maximum voltage while most use nominal. Unfortunately, this makes some comparisons more challenging and adds to potential confusion.
When you charge a lithium-ion battery, it will reach its maximum voltage. Shortly after putting it to use, it settles into a slightly lower voltage—its nominal voltage. The nominal voltage is where the battery spends most of its working life and is roughly 90% of the maximum voltage.
Brands have to choose which one to display. When you see numbers such as 60V Max, that’s a battery that settles into a 54V nominal voltage. When you don’t see “Max” on the battery and packaging, you’re usually looking at a battery that is displaying its nominal volts.
We say “usually” for a reason. Some brands market their maximum voltage but don’t make it clear.
Some European countries regulate stated voltages more stringently, and it seems that it could only serve to help if the simple math all added up.
Best Battery-Powered Chainsaw Accessories
While nearly every chainsaw comes with basic plastic scabbards to protect the chain while also protecting you from the chain, a few of the models go above and beyond.
We’ve seen an optional tip guard to make safe operation more foolproof. Attaching the guard makes you lose a few inches of cutting capacity and prevents any plunge cuts and other non-through cuts such as deep rips. However, casual users may feel more comfortable with the tip of the saw fully protected against kickback.
Once in a while, you can find a unique, form-fitting bag or case. It’s helpful for storage and transportation, though you might want to use it only after you’ve drained the oil from your saw.
Buy Into a System
One other consideration for these saws is the system of battery-powered OPE to which they belong. Like other cordless tools, you can purchase some of our best battery-powered chainsaws as bare tools at significant savings over the kit. If you’re already invested in one of these systems, the overall winner may not interest you as much as seeing which model from your brand is the best in the lineup. Though not the best overall, it might be the best balance of performance and value for you.
Look at the Entire Model Lineup
If you haven’t bought into a system yet and may pick up more outdoor power tools in the future, check out the entire lineup from a brand. Make sure they can fulfill your wish list before going after just the chainsaw. For many users, the saw functions as a secondary tool when compared to the hours you spend with a string trimmer or mower.

Handy outdoor power tools make quick work of tackling overgrown weeds and grass, giving the yard a tidy look and trimming hedges and shrubs. We put battery-powered trimmers through their paces on several grass or weed types to see how well they ran and cut, ultimately arriving at this list of the best battery trimmers.
For ensuring a polished look to a lawn, the best string trimmer is a great investment. These yard-care tools spin a cutting head loaded with nylon string (instead of a fixed blade) to cleanly trim the grass at the edge of a lawn or mow down weedy areas. Though gas and electric models once dominated, new and improved battery-powered versions don’t require mixing fuel or storing gasoline like gas string trimmers do, nor are they limited by the length of an extension cord, like corded electric string trimmers are.
Some battery trimmers are better suited to different-size yards, users, and budgets. So we could help consumers make the right choice, we tested some of the most popular string trimmers to find out how they perform under real-world conditions. To qualify as a top pick, a string trimmer should be durable, powerful, and easy to operate. The string line should exit the reel easily with no need for the user to constantly remove the reel cover and untangle the line.
The following battery-powered string trimmers are at the top of their class. Anyone looking to invest in a trimmer is likely to find one here to fit their landscaping needs.
- BEST OVERALL:STIHL FSA 60 R 36V Battery Trimmer

How We Tested the Best Battery Trimmers
To truly test these battery-powered string trimmers, we started by assembling the tools and charging the batteries. Most trimmers arrived with the batteries about 25 percent charged right out of the box, but a full charge allowed us to gauge runtime at full power. Although some of the trimmers offer lower power settings that could extend runtime, we found that the lower settings simply made them less capable when it came to coarse weeds, so we ran them at full power for testing.
We put each trimmer through its paces in a variety of real-world scenarios: “clean” lawn grass, weedy grass, and natural areas featuring coarse, weedy seedlings and vines. To earn a spot in our lineup, the lightweight 20-volt (V) trimmers had to deliver a clean, crisp cut in both clean and weedy grass sections. In addition to trimming the grass zones, we used the 36V, 56V, and 80V models to cut through woody, viny growth in natural areas. Along with cutting power, we tested for battery runtime, maneuverability, and operator comfort and determined the best battery trimmer by category.
Our Top Picks
These reviews describe the key features of each cordless string trimmer and how the models performed in our backyard tests.
STIHL FSA 60 R 36V Battery Trimmer
It makes sense that the STIHL FSA 60 R would be a top performer in this test group. It comes from a brand with a long history of industry-leading outdoor power equipment. This string trimmer measures just over 66 inches long, weighs less than 10 pounds with the battery installed, and works for about 25 minutes per charge. The 36V 3.9 amp hours (Ah) battery charges in a little more than 2 hours.
The tough polymer material used for the motor housing and debris shield help keep the weight down. A few other standout features include a variable-speed throttle trigger, trigger interlock, battery retainer latch, EasySpool cutting head, bump guard, and hang loop. The trigger interlock and battery retainer latch prevent accidental startup. The variable trigger and EasySpool head improve operating efficiency by saving battery life and minimizing the time it takes to reload, respectively. The bump guard protects sensitive surfaces during close trimming, and the hang loop offers a convenient way to store the tool when not in use.
This is a great all-around pick for quarter- to a half-acre yards. The relatively short runtime of the STIHL FSA 60 R belies a very capable trimmer. In our tests it easily and cleanly sliced through all kinds of grass and weeds, including tough tree saplings up to about ¼ inch thick. The shorter runtime actually mattered less because the trimmer cut so well, and we moved at a faster pace than with some of the other trimmers with longer runtimes.
The other thing we noted here was the amazing level of operating comfort. The trimmer was fairly lightweight to begin with, but the weight was so well balanced—with just enough weight forward of the front handle to keep the head near ground level—that using it required significantly less effort than what was required of some of the other trimmers that weighed about the same. Also, vibration was minimal, so after trimming we had plenty of energy to keep working.
- Weighs less than 10 pounds but easily powers through tough weeds
- 25-minute runtime per charge for about 5,000 linear feet of trimming
- Excellent balance to keep the head at ground level
- EasySpool head, bump guard, variable-speed throttle, and accidental start protection
- Smallish 13.8-inch cutting swath is on the small side for open spaces
- 2-hour recharge time for battery is longer than that of some competitors
Get the STIHL battery trimmer at Ace Hardware or Blain’s Farm Fleet.
Ego ST1511T Power 15-Inch Powerload String Trimmer
Ego Power has made a name for itself in the outdoor power-equipment category by building an affordable battery-powered tool line that competes favorably against old-fashioned 2-cycle gas-powered equipment. The ST1511T 15-inch string trimmer proved to be powerful, clean, and quiet in testing. The 56V 2.5Ah lithium-ion battery delivers up to 45 minutes of runtime, with a recharging time of just 50 minutes. The bump-feed trimmer head comes preloaded with 0.095-inch trimmer line for more cutting force and less noise. Taller users will appreciate the straight shaft design, and the unit weighs in at just over 10 pounds.
In our tests, the Ego trimmer showed ample power to cut through everything in its path, including overgrown, weedy grass; privet seedlings; and honeysuckle vines. Its well-balanced design, with the heavy battery in back offset by the long, straight shaft, made it comfortable to work with and more agile than others we tested. Our only caveat: For seasonal yard cleanup or maintaining larger landscapes, the 45-minute maximum runtime may not be quite enough.
- Auto-loading trimmer head reduces downtime while working
- Adjustable telescoping straight shaft provides a custom fit for different users
- Excellent power and runtime value at a moderate price point
- Heavier than some with less forward weight to keep head down
- Battery is bulkier than others, making the tool tiring to use over an extended period
Get the Ego Power battery trimmer at Amazon, Ace Hardware, or Lowe’s.
BlackDecker LST300 LBXR2020-OPE 20V String Trimmer
To give the yard a polished look without breaking the bank, consider the BlackDecker cordless string trimmer. It features a 12-inch cutting swath to cut down the corners and clean up the edges of small- to medium-size yards. An automatic feed spool means no more stopping to bump the tool when new string is needed. Two 20V lithium-ion batteries are included.
In our tests, this trimmer performed very well in weed-free grass and in weedy lawn areas. With a light weight of just 5.7 pounds, this trimmer is easy to handle without causing arm and shoulder fatigue. The short, straight shaft design is most comfortable for users under 5 feet 9 inches tall. We also liked that with a quick adjustment to the head, the trimmer becomes an edger to neaten up the grass along sidewalks and driveways. In all, we found this affordable tool a solid pick for small obstacle-free landscapes.
- Pack includes 2 batteries for more runtime, less downtime
- Automatic feed spool
- Money- and space-saving design that both trims and edges
- Battery recharges in just 45 minutes
- Best for grass only; struggles with coarse, woody weeds
- Wide debris guard doesn’t fit well into tight spaces
Get the BlackDecker battery string trimmer at Amazon (with extra battery) or The Home Depot.
Makita XRU15PT1 36V LXT Brushless String Trimmer Kit
The Makita XRU15PT1 string trimmer is a premium option to keep the lawn and garden under control. It can handle large yards with enough power to tackle dense weed growth. This cordless string trimmer comes with four 18V 5.0Ah batteries so you’ll never run out of power. Shoppers can purchase this model as a kit that includes a dual battery charger and two sets of batteries, or as a “tool only” for those who already have items from the Makita 18V tool platform.
With a long, straight shaft and high-power cutting head, this 10.4-pound trimmer feels like a pro-quality tool. It was well balanced and articulate while trimming around shrubs and between obstacles. It had plenty of power to cut through tough vegetation. In our tests, it made nice clean cuts and crisp edges in the grassy areas and tore through weedy privet seedlings and honeysuckle vines without hesitation. It’s an excellent candidate to replace gas equipment for medium to large landscapes, though the price may be high for budget-minded shoppers.
- Runtime is longer than charge time for ready-to-go fresh batteries
- Includes a second set of batteries for extended work
- Gas-like power and performance for tough trimming jobs
- Expensive trimmer due to the high cost of batteries
- Small debris guard allows some material close to operator
- Stiff bump head required a hard strike to let out line
Get the Makita battery trimmer at Amazon or Mowers Direct.
DeWALT DCST972X1 60V MAX 17-Inch String Trimmer Kit
When an established leader in pro-grade cordless hand tools enters the lawn-care category, shoppers will want to take note. The DeWALT 60V battery trimmer packs a heavy-duty brushless motor powered by a 60V 3Ah FlexVolt lithium battery that lets it tear through all kinds of tough weeds for at least 40 minutes per charge.
This attachment-capable trimmer comes equipped with a straight shaft and Rapid- loading adjustable spool. It uses.080-inch trimmer line to cut either a 15-inch or 17-inch swath. A safety switch in the grip prevents accidental starts. Users can select high or low power, depending on the project, and control the trimming RPM with a variable-speed trigger. The universal attachment feature lets owners replace the trimmer attachment with a variety of other tool heads, including an edger, hedge trimmer, pole saw, and more.
The DeWALT battery trimmer was one of the heaviest we tested, but also the most powerful. With the standard.080-inch trimmer line that came pre-spooled, this tool had no trouble cutting anything from grass to thin tree seedlings and even tough blackberry canes. In low-power mode it offered more cutting force than the high- power setting of most others we tested. In high range it beat all but the STIHL, which was about an even match in terms of pure power. To be honest, high power was too much for many of our applications, so we also tested thoroughly in low range. It ran about 40 minutes on high, and about 60 on low.
Other than the heavy weight, the only negative point we have to offer is the noise. The trimmer is loud to begin with, and when initially triggering or feathering the trigger it makes an even louder whine/whistle sound. Still, it’s a very impressive tool at a fair price for the power and runtime and a good choice for large properties or cleaning up overgrown areas.
- Battery type: 60V 3Ah FlexVolt lithium ion
- Runtime: 40 minutes
- Weight: 12.95 pounds
- Outstanding power for clearing overgrown weeds and brush
- Works with.080-inch or.095-inch trimmer line for normal or heavy trimming
- Excellent runtime of up to an hour for average grass trimming
- Power head can run other landscaping tool attachments
- Heavy weight of just under 13 pounds, but no shoulder strap
- Longer battery charge time at 135 minutes
- Noisy operation, especially when initially triggering
Get the DeWALT battery trimmer at Amazon, Ace Hardware, or The Home Depot.
BlackDecker LSTE525 20V MAX String Trimmer/Edger
Weighing just 8.8 pounds, this string trimmer is easy to carry, maneuver, and control with an adjustable handle and a safety trigger switch to prevent accidental starts. The 12-inch trimming radius is suitable for keeping the lawn properly maintained without damaging fencing, decks, trees, or other common yard obstacles.
This cordless string trimmer operates with a 20V battery that can last for up to 20 minutes, and a spare battery is included. For edging, simply turn the head and use the built-in wheel to balance as the trimmer string handles the task.
When we used the tool to trim weedy lawn grass patches and edge the curb and driveway, it made nice clean cuts and tracked well to make good straight edges. The shaft and handle adjusted to comfortably fit our 6-foot user. The tool is amazingly lightweight for the amount of power it offers, but the weight is mostly balanced to the front of the handle, and having to manually counterbalance it while working fatigued our tester. Though not built for heavily weed-infested yards, it has ample power and runtime to clean up curb lines, driveway edges, and otherwise maintain a smaller landscape.
- Very lightweight and easy to carry
- Handle is customizable to fit the size of user
- Trimmer doubles as an edger with a simple turn of the head
- Battery provides limited runtime, although a spare is included
- Not enough power to tackle coarse, woody weeds
- Weighted toward the front, which may cause user fatigue
Get the BlackDecker MAX battery trimmer/edger at The Home Depot or Tractor Supply Co.
Echo DSRM-2100 eFORCE 56V 16-Inch Battery Trimmer
A wide cutting swath, extended runtime, and powerful trimming ability make the Echo DSRM-2100 eFORCE battery trimmer an excellent choice for large yards. The straight-shaft trimmer is powered by a brushless motor and 56V 2.5Ah lithium battery for up to 56 minutes of powerful performance that rivals traditional 2-cycle trimmers. It cuts a 16-inch-wide swath to get the job done efficiently.
This battery trimmer weighs in at a comfortable 9.75 pounds, making it a relatively lightweight choice at this level of capability. It features battery-saving low/high power settings for different cutting conditions, a variable-speed trigger, and a cushioned handle grip for comfort. The Speed-Feed cutting head comes preloaded with.095 trimmer line and reloads quickly without disassembly.
The Echo eForce battery trimmer is an excellent value for large-property maintenance. In our tests, the cutting power seemed to be slightly less than that of the DeWALT and STIHL trimmers, but it was still very capable. In high-power mode we trimmed for about 40 minutes. But the better-than-average power and wider swath meant that in 40 minutes with the Echo, we were able to complete work that other trimmers would need an hour to accomplish. The noise level was good, and reloading was fast and easy.
This trimmer could have scored higher with improved balance. Although it is a lightweight trimmer overall, most of the weight is in the working end. The heavy cutting head forces the operator to compensate by lifting upward on the front handle and pushing downward on the rear handle while working. We tested with the 2.5Ah battery that comes standard. Working with the available 5Ah battery (sold separately) would rebalance the trimmer to some degree while doubling runtime and increasing overall weight.
- Excellent price for this combination of power and runtime
- Wide cutting swath and power performance for large properties
- Rapid charging system charges the battery in less than 40 minutes
Get the Echo battery trimmer at The Home Depot or Acme Tools.
Worx WG163 20V Power Share GT 3.0 String Trimmer
Owners of small yards may find this lightweight string trimmer an excellent option. It weighs just 5.5 pounds and easily converts from a trimmer to an edging tool; a built-in wheel helps balance the tool while edging. A push-button feed system gives the ability to extend the trimmer string without bumping the 12-inch trimmer head or manually pulling additional string from the trimmer. It comes with two 20V batteries and a charger, and the battery lasts for up to 20 minutes on a full charge.
This Worx string trimmer tackled our grassy areas with ease, both the weedy and weed-free zones, but it wasn’t as capable on rough areas. We were particularly impressed by the edger function, which we found comfortable and well balanced thanks to the 90-degree shaft-rotation capability. The adjustable trimmer head and upper handle let us customize the working angle, but the process of doing so proved clunky. We had to reach down and turn a rather stiff knob at the connection point between the shaft and cutting head to unlock and relock the angle for each adjustment.
- Trimmer and edger in a single tool
- Smooth push-button Command Feed spool system
- Adjustable head tilts to 90 degrees
- Battery provides limited runtime, although a second battery is included
- Head-tilt adjustment is somewhat awkward and clunky
- Relatively long 60-minute charging time for 20 minutes of runtime
Husqvarna 320iL 40V Battery String Trimmer
One limiting factor of most string trimmers is the cutting head’s direction of rotation; it matters more than one might think. The direction of rotation determines where the clippings will go, and in some situations, how the user should grip the trimmer. The Husqvarna 320iL 40V battery trimmer offers a solution, thanks to its dual-direction cutting head. At the touch of a button, we could change from clockwise to counterclockwise rotation and back, without changing grip on the handles.
This straight-shaft trimmer is powered by an efficient brushless motor and 40V 4Ah battery that drives about 45 minutes of runtime per charge. It features a Rapid-load cutting head that comes prespooled with.080 trimmer line and cuts a 16-inch swath. Low-vibration technology improves operator comfort, and the machine weighs in at just over 10 pounds with the battery.
Anyone not interested in going off the beaten path might still do well to consider this trimmer. Its balance is impeccable, rivaling the STIHL in comfort even though it’s a fraction of a pound heavier. And for quiet operation, this one takes the gold medal. The only real question regarding comfort and control was, why so many buttons? Its four thumb-operated buttons control on/off, high/low power, clockwise rotation, and counterclockwise rotation.
- Dual-direction trimmer head leaves clippings where desired
- Excellent balance for comfortable extended use and less fatigue
- Among the quietest of the trimmers we tested
- The 4 buttons and a trigger seem like too many controls
- Even the high power is not adequate for heavy-duty trimming

Worx WG170 20V Power Share Revolution String Trimmer
While plenty of string trimmers also function as edgers, we found this model to have the best dual-function design. At the push of a button, the trimming head on the Worx WG170 Revolution trimmer converts to an edger that rolls easily along the edge of a sidewalk or driveway. The head tilts up to 90 degrees, so it is easy to reach weeds on slopes while standing comfortably.
The trimmer comes with two batteries plus a charger and three extra spools of trimmer line. The string trimmer also boasts a handy spacer guard that keeps it from bumping into plants, and the shaft adjusts to suit taller or shorter users. It cuts a 12-inch swath and operates on a 20V lithium-ion battery. We tested the tool with the 2Ah battery, but it also comes with a 4Ah battery at some retailers.
In our yard, this trimmer cut through and created a crisp edge on both weedless and weedy lawn areas. We really liked the easy adjustable feature on the trimmer head: A twist lock holds it in just the right position, up to 90 degrees, for a customized working angle for users of different heights. Also, the batteries are interchangeable with those of many other Worx 20V cordless tools.
- Adjustable upper handle to accommodate users of different sizes
- Trimmer head converts to an edger for use along sidewalks or driveways
- Comes with 2 batteries to make up for shorter runtime
- Requires a relatively long charging time
- Trimmer feels underpowered for tackling coarse, heavy weeds
- Only 20 minutes of runtime per charge

Greenworks Pro 80V 16-Inch Cordless String Trimmer
The Greenworks Pro 80V trimmer is a quality tool that adapts to a variety of other functions with attachments such as a brush cutter. (However, attachments are sold separately.) The 2Ah battery provides up to 45 minutes of runtime and recharges in just 30 minutes. The brushless electric motor is efficient and quiet, providing plenty of torque to cut through heavy weeds without the noise and smell of a gas-powered unit.
In our test areas, the Greenworks Pro trimmer was powerful enough to cut through the toughest weeds and vines with ease. The heavy battery weighs the machine down toward the rear, but the included adjustable shoulder strap makes operation more comfortable. The battery is compatible with other Greenworks 80V tools. Just don’t get too excited about the variable-speed trigger: Although it’s intended to allow a gradual increase from “off” to “high” speed, we found the range of movement between the two to be minuscule; in effect, the trimmer is either “off” or “on.”
- Battery type: 80V 2Ah lithium ion
- Runtime: 45 minutes
- Weight: 10.6 pounds without battery
- Trimmer has a quiet, efficient brushless motor
- The recharging time is only 30 minutes; runtime is 45 minutes
- Gas-like power and performance without the noise and smell
- Slight lag time between triggering and full power
- The trimmer’s adjustable speed feature is difficult to use
- Weight is balanced toward the rear, but shoulder strap helps

What to Consider When Choosing a Battery Trimmer
When shopping for string trimmers, also known as weed eaters, keep in mind yard size, how often the tool will be used, and the height and strength of the primary user. The following key considerations will help in selection.
Trim width, also called swath width, indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must have, which often means the tool will be heavier because it will require a larger, more powerful battery.
Running a string trimmer requires a hefty dose of power. Though most of today’s trimmers run on rechargeable lithium-ion (Li-ion) batteries, a few accept nickel cadmium (NiCad) batteries. Li-ion batteries are more powerful, but NiCad batteries are less expensive (an average of 70 to 125 less). Li-ion batteries also are smaller, hold a charge longer, and provide full power throughout the discharge cycle.
NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will “remember” the earlier charge level and won’t hold a longer charge in the future. If choosing a trimmer that has a NiCad battery, let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-ion battery will be the best choice.
Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to an average of 60 volts of power. powerful batteries at the high end often are intended for commercial use and can cost 200 or more per battery.
Some string trimmers in this category sell without a battery (or battery charger), which the user must purchase separately. This could be a cost-saving benefit for those who are adding to a same-brand, battery-compatible cordless tool collection, since the same battery will power multiple tools. However, it can be more convenient to purchase a kit with multiple batteries to have one on the charger while the other is in use.
The “feed” of a string trimmer indicates how the trimmer head releases additional trimmer line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer (the area where the spool attaches) on the ground to release a few inches of fresh line.
Some newer models feature an auto-feed sensor that gauges the length of the strings and releases more when needed. Still others have a push button to release more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.
Curved vs. Straight Shaft
Some string trimmers feature a straight shaft that runs from the handle to the cutting head, while other models feature a distinct curve in the lower shaft about two-thirds of the way down. Some users find curved-shaft trimmers to be easier to operate since the spool end already rests at a handy angle for weed whacking.
Straight-shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on the task at hand. In general, straight-shaft trimmers work better for users at least 6 feet tall, while shorter users will appreciate curved-shaft trimmers.
Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels (about as loud as a motorcycle passing by from 25 feet away). By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to casual conversation.
Those who are still unsure about how to use a battery string trimmer may find the following answers to common questions about these tools helpful.
Q. Can a string trimmer cut weeds?
A string trimmer is used to cut and control weed growth around the home and garden. However, light-duty trimmers may have issues with very dense weed growth.
Q. Can you use a string trimmer to cut grass?
A string trimmer can be used to cut grass, though you need to be careful not to cut the grass too short while trying to keep the trimmer balanced. It isn’t the easiest way to cut the grass, but it is possible.
Q. Can you edge with a string trimmer?
Yes, a string trimmer can be used for edging the garden, driveway, walkway, or sidewalk. If you have a large yard, it may be better to invest in a separate edging tool.
Q. How many volts should be in a trimmer?
String trimmer batteries average from 18 volts up to 80 volts. Typically, the higher the voltage, the longer the battery life.
Q. How do you edge a lawn with a string trimmer?
Hold the string trimmer perpendicular to the lawn to keep the cut even. Position the head about 4 inches off the soil so the string has space to rotate. The string should rotate and cut through the grass and dirt. As you move along the desired borders, keep the head balanced and even. Clean up the cut grass and dirt to finish the job.

It can then be stood up against a wall or hung up, and even comes with a handy hook. The 30l grass bag also flattens down to take up very little room and can be hung on the mower. The Aspire is light, with a carry handle so that lifting it up steps or into other areas is easy and it has an adjustable handle to suit different height users.
