Proper charging of an electric screwdriver of a new battery. Electric screwdriver battery device

How to charge and store the battery of an electric screwdriver

Electric screwdriver is one of the most popular in the home and professional activities of power tools. It allows not only to tighten and twist various types of fasteners, but also to drill holes. By the method of power supply, the devices are divided into network and battery. Models with batteries are practically not inferior to their performance tools operating from the 220 V network. In this case, with their help, you can perform working operations in autonomous mode. It is also convenient that the supply cord does not limit the movement. But you should correctly charge and store the battery of an electric screwdriver so that it serves for a long time. Many problems with the battery block can be eliminated independently by using the cause of the malfunction by a multimeter.

The battery is source of energy for wireless models of screwdrivers. Due to the leakage of physico-chemical processes (electrolysis), this element accumulates electricity, and then gives out a constant voltage of the desired value at its corresponding outputs. Voltage and capacity are the main parameters of any drive. The first shows the potential difference between the cathode and the battery anode. The voltage is measured in volts. The capacity determines the amount of current issued in 1 hour of the battery, so this parameter is measured in ampere hours.

In different models, the battery block (battery) looks and is arranged in a similar way. It consists of the following structural elements:

  • hulls with contacts located on it;
  • feeding elements (batteries);
  • Temperature sensor circuits (termistor), which performs the function of protecting the block from overheating (the range is from 50 to 600 degrees).

Not all models are equipped with thermistors. The case usually is a plastic box consisting of two parts. He contains mainly about 10 batteries, and sometimes their number more. In this case, the nutrition elements are connected to each other in the chain. Free terminals of extreme cans are connected to the contacts located on the case designed to power the tool electric motor and connection to the charging equipment. The output voltage of the battery is determined by summing up this parameter of all batteries connected to a single circuit.

  • 2 power (“”, “-“) designed for charging and discharge;
  • one top controllers associated with thermistor;
  • One contact used for charging from special stations that can align the value of the charge in all power elements available in the block.

By the type of power supply, batteries are divided into such types:

  • nickel-metallological (indicated-nimh) with a voltage of 1.2 V;
  • nickel-cadmium (marked nicd) at the output also issue 1.2 V;
  • lithium-ion (designated by Li-Ion symbols), in which the voltage depends on the number of supply elements in the battery and can be in the range of 1.2-3.6 V.

The lithium-ion batteries have a control fee. At the same time, a special controller monitors the operation of nutrition elements.

A separate battery consists of the following structural elements:

  • positive and negative contacts;
  • electrode with a positive charge;
  • external coating of the case;
  • electrolyte;
  • negative electrode.

The most widespread nickel-cadmium energy drives due to an affordable price, compact size and a large capacity. They can be reloaded more than 1 thousand times.

General rules for charging batteries

To correctly charge the battery of an electric screwdriver, a certain external temperature regime must be provided. The optimal air temperature is considered from 10 to 40 degrees. An undesirable moment is the possible overheating of the battery block during the accumulation of the charge. To avoid the possible negative consequences of such a phenomenon, it is necessary to disconnect the battery for cooling from the charger.

It is not recommended after the batteries are gained by the full container, leave them in the charged device disconnected or inserted into an electric screwdriver, which will not be used, it is better to put them in the case from under the tool.

Battery blocks that are not used for a long time are recommended to recharge once within a month.

The recommended battery charge time is from 30 minutes to 7 hours and depends on its type. For a specific model of power tools, it is indicated in the operational instructions. These instructions should be accurately performed so that the product lasts a long time. Most charging devices are equipped with indicators showing at what stage the process is located. In such cases, it is not difficult to determine how much the nutrition elements need to be charged with the LEDs of a certain color. After reaching the full level of the container, you need to immediately stop the process.

Recommendations for charging batteries of different types

Despite the rapid development and weighty advantages of LI-IN technologies, batteries of different types are used to power screwdrivers-from old Ni-CD and Ni-MH to modern Li-Ion and Lifepo4. Each type of power sources have their own characteristics, in t. h. And concerning charging.

Nickel-cadmium batteries

Due to the high toxicity of cadmium, the nutrition elements with such a chemical composition are used less and less. Most manufacturers abandoned them. But if you have a tool with this type of battery, remember that you need to charge it from a minimum border up to 100%. On average, you need 6-8 hours to replenish the charge.

Due to a severe memory effect, the Ni-CD batteries must be completely discharged before each subsequent charge. Otherwise, they perceive the level of residual charge as a discharged state and, with subsequent operation, give the capacity only to this level.

proper, charging, electric, screwdriver, battery

In other words, they will give only the supply of the container that they received at the last recharging. As a result, the volume of the useful capacity of cells and the time of their autonomous work on 1 charge are reduced. It is also necessary to charge nickel-cadmium elements completely. Incomplete charge leads to a decrease in the capacity and premature wear of the batteries.

Ni-MH cells also have a memory effect, although they are more pronounced in them. Therefore, it is recommended to charge them according to the same principle: first, completely discharge, and then charge. For new batteries, you need to perform at least 5 cycles of full discharge and charge. With further operation, alternating partial charges with complete. It is also recommended to store such batteries in a loaded state. Charging time NI-MH elements on average is 8 hours.

Lithium-ion batteries

Li-Ion batteries are most convenient to use and charging. Their effect of their memory is so small that it allows you to do partial charging without harm to the battery at any residual charge level. It is not necessary to completely discharge them before connecting to a charger. It is enough to perform 1 full cycle with primary use and further carry out such training cycles every 3 months.

After staying in the cold, lithium battery should be kept for about an hour at room temperature before charging. At low temperatures, chemical processes slow down, and a temporary decrease in the capacity is observed. With subsequent warming to the plus temperatures, the normal course of chemical reactions is restored, and the batteries are able to fully accept the charge.

Depending on the size of the charger and the container of the lithium battery, it charges from 30 minutes to several hours. The self.discharge of such elements is insignificant. up to 5% per month. It is recommended to store them with a partial charge level (40–70%) and intermediate recharging during long storage. BMS board does not allow the reloading of cells and their deep discharge.

But if you leave a sowing battery without recharging for a long time, its voltage may fall below the minimum border. When stored in a deep discharge state, lithium-ion batteries are swollen, become unsuitable and dangerous for operation. Therefore, the protection board does not allow their connection to the.

Performing the training cycle

On the question of how to correctly charge new batteries for an electric screwdriver, an algorithm of action is the same for models of all types. You need to perform the training cycle:

  • Dissolve the battery with a current of 0.1C or turn on an electric screwdriver without load and work with 3-minute breaks.
  • Connect a discharged battery block to a charger and wait for the end of the process.
  • Disconnect from the network. Wait half an hour.
  • Re.connect the memory and wait for it to turn off.
  • Turn off the visits from the network again and wait 20-30 minutes.
  • Connect the charger again and wait for it to turn off.
  • Wait half an hour to fully stabilize the voltage.
  • For models Ni-CD and Ni-MH-repeat the entire cycle, starting with discharge, 3-6 times. For lithium-ion batteries-1 cycle is enough.

How to charge the Li-Ion battery of a screwdriver

Brought a couple of weeks ago 6 Makitovs devices for repair.

4 screwdriver, 1 jigsaw and 1 grinder.

Voiced me a repair price. It turned out that only one screwdriver had an economic meaning to restore. The rest went to spare parts.

In general, it was time to replace a manual battery tool for itself.

So I bought new screwdrivers with Li-Ion batteries for all the carpets at once.

The guys are accustomed to ni-CD batteries, and Li-Ion requires a completely different approach. Directly to the opposite.

And, of course, it is not only about how to charge the Li-Ion battery of the screwdriver. If it is wrong to discharge and/or store it, it will also be little good for him.

Therefore, I looked at a couple of dozen sites and a couple of hours video.

Threw all the husk and made the most “dry” squeezing without “water”.

How to charge the Li-Ion screw of screwdriver and other important rules for its operation

  • Li-Ion works optimally in the range from.10 to 45 ° C. Charge at a temperature of 10 to 30 ° C.
  • 1 time every 4 months, carry out a full cycle of discharge-rack for calibrating the charge sensor in the battery controllers. That is, discharge to almost 100% and put for charging for 12 hours.
  • Store Li-Ion on the charge of 40-60%. It is impossible to store charged by 100% Li-andi, since in this case it will forever lose 20% of the container in 3 months. With proper storage-with a charge of 40-60%-Li-Ion will irrevocably lose only 1% of the capacity in the same 3 months.
  • If the screwdriver is equipped with two Li-Ion, then charge one up to 40-60% and store it as a backup. Use it as a worker once a month-charge it to 100%, discharge to 40-60% and leave again for storage. The second Li-Ion is the main worker. We have worked. at the end of each day, put it for recharging, even if it is discharged by less than 10%.

Reserve Li-Ion use if the main Li-Ion worker is discharged as a result of intensive work and there is no time to wait for it to charge.

That’s all. Now you know how to charge Li-Ion battery for an electric screwdriver.

I handed this to every joiner, and I also hung ads in the workshop on the board.

And there may still be a question-why did I switch from Ni-CD to Li-Ion batteries?

Here are the advantages of LI-Ion batteries over NI-CD:

  • at least 2 times a large specific container;
  • self.discharge is several times less;
  • lack of memory effect, which makes it possible to recall at any time;
  • It withstands an average of twice as many “charge-discharge” cycles, that is, it will live twice as long.
  • Li-Ion is subject to aging. Well, and ni-cd eternal or something? They also get old.
  • Li-In has low stability when working at low temperatures. All this is in the past. Now Li-Ion is doing such that they work and.10 ° C Stopudovo. And in some sources it is indicated that with.30 ° C can work;
  • Li-Ion require the use of only the original charger. Well, what is there? All screwdrivers are sold just with their original item in the kit.
  • Li-ion has a high cost. Yes, I wouldn’t say anymore. Recently went to the store. Ni-CD batteries below 1 t.R. did not see. And on AliExpress you can buy a whole electric screwdriver with Li-Ion for 3 tons.R.

Well, finally, if you work with an electric screwdriver professionally-do not hesitate especially-it will crumble at the same time with the Li-Ion battery. So buy a separate batter separately you do not have to.

Just with a reasonable non-edged use for a couple of years, an electric screwdriver should be enough.

And, yes, one more important rule. Do not save on the power of an electric screwdriver. It corresponds to the voltage of the battery. Take a 20-volt minimum. Will twist like a beast.

And buy weak. there will be little sense from it, and there will be no joy from penny savings either.

I generally scored screwdrivers with Li-Ion batteries at 25 volts. The joiners are not loud. Especially after Ni-CD for 14 volts.

Look like that’s it. There were questions, do not agree with something-write to Комментарии и мнения владельцев.

How to charge the ni-cd screw of screwdriver

But many questions came about how to do the same with Ni-CD batteries.

I was always touched by this moment when a businessman whose site is visited by one and a half people, so writes.

Today visit an average of 110 people a day.

proper, charging, electric, screwdriver, battery

And, apparently, including few fans of batteries.

So little that there was not a single question.

Either I got everything as clearly as possible and briefly state about LI-Ion batteries.

Either because the ni-cd screws are no longer pinning anyone.

Then you may begin to begin a completely fair question: “So on what a dog, Dmitry, you will post a topic that is not interesting to anyone?””

Firstly. I have 2 working screwdrivers left in my workshop with ni-cd batteries. I would like them to go out of their term, and not die in adulthood.

And there is a strong suspicion that today in the hands of the population of 80% of the screwdrivers with Ni-CD and 20% with Li-Ion batteries.

Secondly. The habit of a sequence.

Since I studied the topic Li-Ion, I once again studied the topic Ni-CD.

There has already been a similar memo on Ni-CD, but the inappropriate cocepage, an indefatigable craving for knowledge plunged me into the jungle of the Internet again. And the memo was significantly updated, simplified, became more understandable and specific.

Thirdly. If the people do not ask questions, then this does not mean that this or that topic does not interest him. This is generally Russian mentality. not to show his incompetence to anyone. We, often easier for us, are easier than everything they will ask and find out about everything in advance.

Although, why only in the look from time to time in the UTYUB a cognitive TV and explorations on the topic. how is there, behind a hedgehog?

Well, so, for those who are interested in the topic, but do not confess to this. this article will be “in the vein”.

Fourthly. If you didn’t know, then here you have a little life hack. The blog is extremely useful in that in posts you can leave serious blocks of information on narrow topics.

But imagine. you are doing a certain business and you have a blog with a lot of posts on your business topics. It is clear that it is extremely desirable that in these articles you competently, reasonably and structuredly reveal these issues.

And then life goes on, all sorts of things, business processes, correspondence with partners, suppliers and clients.

You will inevitably ask you or just touch in the discussion those topics that you have already covered on the blog.

And here it is! You do not need to strain and spend a lot of time to explain to a person what’s what. You just give him a link.

I spied on this life hack even with Lyubishchev. In the book of Granin “This Strange Life”.

Fifth. You really think that you can post a blog once a month?

No, of course, you are right. You can write something to the blog and once a year.

proper, charging, electric, screwdriver, battery

Only if it is a commercial blog, then it will not be cool at all.

Yes, because the attendance of your blog depends, including on the frequency of its update. That is, from the frequency of its replenishment with new unique materials.

Well, now imagine. 5 people per day visit your blog.

OK then. Then imagine that it is visited by 10,000 people a day.

This is a completely different turnover of events. Such a movement with proper monetization will easily bring you from 100 tons.R. per month (if you move a minimum, only by advertising) up to 3 million. (if you move your info- or material products).

So, in order to jump out for 1000 visitors per day, you need to post at least 1 article per week.

“At least” because it depends on the topic of your blog.

So that the site on such a narrow topic, such as health products from cedar, reaches 1000 visits per day, you need to post 1 article per day.

But I won’t pull so much. I write everything myself. I don’t hire literary blacks of copywriters.

There were several attempts. Disappointed. For 2 t.R. They will not write anything good copywriters. And experiments with a guru from 10 tons.R. I don’t make a

Well, maybe affordable. But it’s a pity very much.

At sixth. When you regularly fill your site with content, the search engines begin to look at it more favorable.

And this means that he becomes more visible to people and knows better in the issuance of Yandex and/or Google.

This metrics came from where came to the Fitosauna visitors. Including for cedar barrels and infrared saunas.

If you are far from this, then of course not. If in the subject, then they noticed, of course.

I spend exactly 0 on advertising (!) rubles a month.

Now, on the Internet, with the help of free special services, it is quite easy to evaluate the approximate budget of competitors.

So, other manufacturers of phytobs and infrared saunas fill the Internet with their advertisements worth an average of 100,000 r. per month.

So, the Internet is shedding properly, I processed the previous memo on how to charge Ni-CD batteries. And also discharge them and store them.

I draw your attention that some points can not be found anywhere on the Internet. Personally, I have not met. Because in the memo there is information that I got during communication with the recovery master of ni-CD batteries. His personal experience.

How to charge, discharge and store ni-cd batteries

How to determine: the screwdriver still twists weakly, but the turns fell noticeably. This means that the battery is discharged to about 5-10%.

  • Recommended charging temperature from 10 ° C to 30 ° C.
  • Recommended operation temperature from.20 ° C to 40 ° C.
  • You need to charge only an original charger. That is, to those that came with a screwdriver. It is desirable that the charger has the function of automatic shutdown through the number of hours determined by the manufacturer. When buying a screwdriver, pay attention to this.
  • Before putting it on charging, let the battery cool for 20 minutes.
  • After charging, let the battery cool for 20 minutes. Then insert it into a screwdriver.
  • Store the Ni-CD battery must be discharged (up to 5-10%).
  • After storage of more than 6 months of the Ni-SD battery, you need to “train”-make 5 cycles of charge and discharge.

By the way, a sign that paragraphs 5 and 6 were not respected. “dead” batteries are inflated. So it is clear that they did not care about their duration of “life”.

That’s all. Now you know how to charge, discharge and store a NI-CD battery for a screwdriver.

Features of charging batteries of different types

Differences in the charging of batteries are associated with the properties of materials from which the battery is made. Devices for replenishing the container are pulsed and ordinary. Professional power tools are the first to supply, and the latter are complete with household screwdrivers.

There are three types of batteries in total:

  • Nickel-cadmium. Differ in a pronounced memory effect. After buying, they must be charged and discharge 3 times. Only in this way will the largest battery capacity be achieved. Subsequent charging should only be carried out after the complete charge of the charge.
  • Nickel-metallological. Also have a memory effect. A similar procedure is recommended to perform 4 times. Further recharging is carried out arbitrarily.
  • Lithium-ionic. These batteries are the most unpretentious. They are able to not change their original capacity for a long time. They can be charged as you like.

Is it necessary to charge before long.term storage

If an electric screwdriver has stopped charging, you can never disassemble the tool yourself, otherwise you can lose a guarantee. It is best to take a broken device to the service. Sometimes the operating instructions contain information about measures that need to be undertaken in such a situation.

Proper charging the battery is the key to its working work. If you do not neglect the rules, new batteries will not be needed soon.

How to charge a battery for an electric screwdriver without a charger

If the charger is out of order or lost, then to work with the battery you can use:

The advantage of the charger for the battery of the car is the value of the outgoing voltage. It does not exceed 16.5 volts, so it is suitable for an electric screwdriver by both 16 volts and 18 volts.

If the original factory ZAM is lost, then the universal charging should be used. It regulates the values ​​of the voltage, current strength and resistance. Parameters can be adjusted independently according to the instructions.

Various DC source is also suitable. The main condition is the presence of a higher voltage relative to the battery of an electric screwdriver. Exceeding the nominal value is permissible by 10-20%. Nickel-cadmium and nickel meteric battery will not withstand the charge current of more than 0.5 C, and lithium-ion-not higher than 1 c. The current values ​​will have to be adjusted independently, you will also have to follow the temperature of the charged battery.

Self.charging the battery using an external power source

Restoring the battery capacity of the screwdriver using a power source requires critical temperatures, input voltage and current parameters. If you do not follow them, then the reload will happen. The pressure will increase inside the battery, the decomposition of the electrolyte will begin, which can lead to a gap.

You can use external power sources only if there are no other ways to charge the battery. It is important to observe the polarity of terminals and safety precautions. You can only hold on to isolated rubberized wires that do not pass electric current.

If the battery of an electric screwdriver does not charge

The reasons that the battery of an electric screwdriver is not charged, there are several. The problem is the elementary wear of the battery, as well as a violation of the integrity of the contacts of the charger. Then it should be disassembled and bent in the right direction.

Contacts can be oxidized and polluted. Failure to comply with storage conditions will lead to a violation of the charging cycle, the time of restoration of the charge can both increase and decrease. Contacts of the battery and charger must be periodically wiped with special cleaning pastes.

The reason for the failure of the nickel-cadmium and nickel-metall hydride battery may be the effect of memory. If the battery is repeatedly charged before the expiration of energy reserves, then the number of chargers will gradually decrease in it. In the end, a breakdown occurs. Over time, the battery cycles and discharge cycles end. The most durable is Li-Ion type, nickel-metallogids of power has been working for less long.

Types of batteries

In order for the battery for a long time “like a clock”, you need to first familiarize yourself with the instructions attached to the device. It should be noted that the screwdrivers differ not only in price, power, manufacturer, but also divide into professional and semi.professional. Accordingly, batteries will also have a different price, quality and capacity of the charge. Professional types are equipped with more capacious power sources that will cost a level more expensive, but will also work longer than ordinary. Manufacturers use various batteries in the manufacture of their devices, each of which is endowed with certain parameters and features that should be taken into account during recharging. Squire batteries can be classified into the following types:

Are considered the most powerful batteries. They are quickly charged, as well as in them a complete lack of memory effect. To recharge this type of battery is easier. There is no need to recharge it after complete discharge, it is allowed to nourish as needed. The high cost and intolerance of low temperature repulses the desire to buy from many people, so they are not too in demand. Battering should be charged at a temperature of 10 to 40 ° C. If the battery heats up during the charge, it must be cooled to avoid further breakdowns.

Nickel-cadmium ni-cd

Nickel cadmium battery is endowed with compact dimensions and large capacity. Following the attached instructions, they can be fed more than 1000 times. There is a memory effect if it is charged before the full category occurs, this can lower the energy intensity. Before the first use, you need to charge at least three times and discharge the battery. In the future, it is also recommended to completely discharge and charge the device, this will make it possible to bring the capacity to the required working condition. The same rule is applicable during the storage of the tool.

Nickel-metallhydridic ni-mh

Belong to the latest generation of batteries, for this reason, the memory effect is somewhat weaker than the previous variety, which is an undoubted plus. NMGB shortcomings. the highest current of self.discharge. For the battery for a long time to function, it must be kept charged. In the case of prolonged non.use of an electric screwdriver (about a month), it must be completely reloaded.

As you can see, each battery is endowed with characteristic features, given which, it will be possible to correctly charge an electric screwdriver.

Features of charging of one or another type

The initial charging of an electrical screwdriver is considered a very significant factor, since it depends on it whether the full charge capacity will become an active one or not. Any type of battery has its characteristic features of primary recharging. The process of recharging the nickel-cadmium battery is somewhat complicated. Initially, it needs to be recharged three times in a row, and so that the charge capacity remains filled.

Nickel-metallhydrid view for the first time is recommended to be completely discharge, and also completely charge. The circle of full charge/discharge is repeated 4-5 times, then you can safely charge and discharge the battery, regardless of the fullness of the container.

There are no special rules for lithium-ion, the capacity remains unchanged for a long time.

Advice! Overheating of a power supply over 50 degrees cannot be overheated.

Features of charging screwdrivers with different stresses

Batteries for screwdrivers differ in Voltage. 12, 14.4 and 18 volts. Charging devices that come with the tool correspond to the battery face value. It is not allowed to charge the equipment with the help of a disabled voltage, This can lead to a battery breakdown. When buying a new item, you need to choose a device with the same characteristics as that of a broken device or acquire a universal one, with the ability to set the necessary value.

Checking the status of the battery multimeter

A device such as Stht0-77364 can help you find malfunctions in different electronic components, including screwdrivers batteries. It is most ideal to use it in pairs with other testers for the merit of reliability. This allows you to check the characteristics and calculate the error.

Cordless Screwdriver battery replacement/upgrade

Note: Before proceeding to measurements, you need to make sure that the multimeter itself works. To do this, you just need to connect it to the outlet, coupled with another similar device and check the readings.

Non.traditional battery charging methods

Sometimes it happens that there is no charger at hand, and the battery spent all electricity. Then you can resort to unusual recharging methods. Having sorted out such methods, it must be borne in mind that the devices each other should be as similar as possible.

Car charger

First of all, it is worth considering the output voltage of battery charging. It is impossible to make the parameter exceed 18 volts. It is recommended to use new automatic charging devices that have the function of changing the issued voltage. Having set its parameters, the battery will not threaten anything. An important condition will not be recharged the battery. The current strength for automobile charging should be no more than 10 percent of the total battery capacity.

Homemade device

You can try to build your own device for recharging yourself. This will require a power supply from your native charging or laptop. The most important thing is to observe all the required parameters.

For manufacturing, you will need the following components:

Lithium-ion models of batteries have a functional feature. They are able to recharge from a USB unit. The only nuance must ensure observation in order to prevent a reloading. The current should not be more than one ampere. The easiest way is to purchase a USB separation that will provide all the necessary parameters and elements.

An example is the old battery, which has some kind of small malfunction or was restored for further work in the form of an external power source. It will work about the same as an ordinary out bank. It is important that she has similar properties and technical characteristics. Such a charger is possible to do independently only to a knowledgeable person. He must have minimal knowledge in the field of electronic devices and the creation of electrical circuits. To create, you need 10 ampere fuses, as well as wiring with a section.

What to do if the battery does not charge or holds a charge

If the battery does not charge, there may be several reasons for this.

In the event of the first two points, you can solve the problem if you replace the battery with a new. There are cases that the battery contacts were bent after a long use. To do this, with the help of nippers or other tools, you can return metal antennae to place.

If the problem is not this, it is also recommended to check the condition of the metal plates. They can oxidize or could have a strong sulfation. Enjoy paper will help to get rid of oxidation, and a special solution will temporarily save from sulfation.
