The use of a cordless screwdriver does not depend on the presence of a nearby power supply, which increases the comfort of working with the tool. Screwdrivers are intended for professional and domestic use. Accordingly, the batteries for them differ in quality, price and capacity. Recent times manufacturers produce rechargeable batteries (batteries) with sufficient power for the tool with a relatively small size of the power source.

The battery for a screwdriver is a set of elements (cans) connected in series at the bottom of the tool body. Supply voltage range for various models screwdrivers is 9-18 V. EMF professional tool can reach 36 V. The higher the voltage of the supply element, the more powerful the tool. The more capacity in each battery, the more time it can work without recharging. The battery capacity of household screwdrivers is within 2.7 A / h.

Battery types

Everyone knows how a rechargeable battery works. school course physics. The power supply consists of 3 main elements: anode, cathode and electrolyte. When charging the device with chemical processes in the electrolyte there is an increase in the potential difference between the electrodes.

Most often, nickel-cadmium batteries (Ni-Cd) are used to power screwdrivers. Devices of this type have the following features:

1. They differ in low cost and rather big capacity. Designed for 1000-3000 charges. Battery life varies by model, usage pattern, and charging pattern.
2. Reduces the duration of operation of this type of device having a memory effect. If the cells are charged until they are completely discharged, the capacitive qualities of the battery deteriorate over time. In this case, crystals form on the contacts of the device, which also reduces the capacitance of the device.
3. Another disadvantage of a nickel-cadmium battery for a screwdriver is the toxicity of the materials used for its manufacture. chemical substances. In European countries, the use of this type of battery was abandoned.

If a tool with a Ni-Cd power supply is used infrequently, over time, the original specifications may decrease by 3 times. At regular work with a screwdriver, the battery can last up to 2-3 years. At the same time, it must be operated at an ambient temperature of at least 0 ° C and in the absence of high humidity.

Nickel-metal hydride (Ni-MH) batteries for a screwdriver differ from the previous type of battery in the following technical characteristics:

1. During their manufacture, operation and after disposal, there is no danger to human health.
2. The memory effect they exhibit is much less than that of Ni-Cd batteries.
3. The disadvantages of devices of this type include rapid self-discharge. When left for a long period of storage, they must be charged, and if the battery has not been used for a month, then it should be charged again.
4. The device is sensitive to operation with maximum load. Rapid discharge reduces its capacitive properties over time.

The new generation of power cells include lithium-ion batteries (Li-Ion). You can recharge them at any time, regardless of the degree of discharge.

The devices are environmentally friendly, but work with a screwdriver with Li-Ion batteries when negative temperatures ah not desirable.

Tools with such a power source are not yet very common only because of high price for products.

A replaceable battery for a screwdriver is a rather expensive element, because its price share in the total cost of the tool reaches about 30%. Therefore, it is not at all surprising that many craftsmen are trying to extend battery life. various methods. How to restore the battery of a screwdriver? - we would like to reveal such a topic in today's thematic article.

Design features of the battery for a screwdriver

Regardless of the type of power tool, brand and its specifications the structural structure of the batteries is not much different from each other. After all, when disassembled, the battery is a series circuit consisting of identical batteries.

Moreover, in most cases (for various types batteries) such cells have the same size and output voltage (V), and differ only in capacity, which is expressed in mA / h and is indicated on the cell body. In addition, at self repair A battery for a screwdriver should pay attention to the type of elements used (Ni-Cd, Li-Ion, Ni-MH), since the recovery method for each of them may be slightly different.

It should also be noted that in order to be able to charge the cells and power the power tool, the battery design provides for power contacts (“+” and “-”) connected to the outputs of the serial circuit. Well, to protect the equipment from overheating (with forced) charge and equalize the charge level on all battery banks, two more control contacts are used through which the thermistor and resistance are connected.

Battery Failure Detection Method

Given the series connection of batteries, the primary task of the contractor will be to search for a “weak link”, because if at least one element fails, the battery will function with significant technical deviations. If we take into account that the simultaneous failure of all components of the circuit is not possible, it should be understood how to determine deviations individual elements nutrition.

Method 1. Use a multimeter

Given the identical voltage level of all components of the circuit, you can determine the faulty element using a multimeter (switching it to DCV voltage measurement mode). It should be remembered that the nominal voltages for different types of batteries have different values:

• Ni-Cd and Ni-MH (voltage 1.2V);
• Li-Ion (voltage 3.6V).

The very same method for determining a failed battery is carried out according to the following algorithm:

• The battery is set to full charge;
• The case of the device is disassembled, and alternate voltage measurements are made (using the device) on each of the cans;
• Elements are marked, the voltage on which is lower established norm(for Ni-Cd and Ni-MH batteries, the voltage should vary in the range of 1.2 - 1.4 V; for Li-Ion - in the range of 3.6 - 3.8 V).
• The battery is assembled and installed in a screwdriver, after which it should be discharged until a noticeable decrease in power, for which a number of power operations can be performed using a power tool.
• After discharging, the battery case is disassembled again, and again voltage measurements are taken in all sections of the circuit (special attention should be paid to marked elements)
• In the event of a voltage drop on the element of 0.5 - 0.7 V, such a battery is considered unusable.

Method 2. Use the load

The technology for detecting weak batteries in this case is similar to that described above, with the only difference being that a 12-volt light bulb (for example, 40 W) is used to discharge the battery, which will act as a load. And in order to solve the task, it will not be necessary to assemble / disassemble the battery pack several times.

After completing all the above manipulations, all unreliable elements of the battery circuit are determined, and after that a decision is made to replace or restore them.

Restoring battery cells

It should immediately be noted that it is almost impossible to restore the Li-Ion battery of a screwdriver, and all that can be done in this case is to identify weak elements and replace them.

Sometimes the problem may be hiding in the charger, which is why special attention should also be paid to the correct operation of it.

If we talk about the resuscitation of blocks, then the recovery method can be applied exclusively to Ni-Cd batteries, which are the most common for screwdrivers.

Among the main methods for the recovery of Ni-Cd batteries are the following:

• Sealing (compression);
• Elimination of the memory effect;
• Addition of boiled-off electrolyte.

How to eliminate the "memory effect"

Sometimes, the battery needs to be restored, which is associated with erasing the memory effect. Moreover, recognizing such a “disease” is quite simple: after a full charge, the battery discharges very quickly, and can again function after a short time delay. You can partially eliminate the "memory effect" as follows:

First, the battery is fully charged (if possible) with a small current, after which the battery should be completely discharged, applying a small load and thereby ensuring a slow (soft) discharge, which will allow not only the outer layer to sink, but all the plates as a whole. In this case, it is advisable to use an ordinary lamp with a voltage of 220V and a power of 60W as a load and discharge up to 30% of the rated capacity (up to about 5V).

Before using the battery, the above procedure should be repeated at least 5 times. And although the capacity of such a “reanimated” battery will be somewhat lower than a new battery, nevertheless, as a temporary measure, this technique is quite successful (it can extend the work for at least a year).

Addition of boiled off electrolyte

The most common problem with batteries for a screwdriver is the boiling of the electrolyte (especially with a forced charge), which is why it is on the solution of this issue that we should dwell in more detail.

So, after determining the failed cans, you should cut the connecting plates and dismantle the required elements. After that, using a thin punch (with a diameter of not more than 1 mm), a hole should be made in the body of the can (from the minus side), through which it is necessary to add from 0.5 to 1 cubic centimeter of distilled water inside the element (having previously pumped out the same volume of air). final restoration work will seal the jar (you can use epoxy resin) and connecting the element to an existing circuit.

In the future, in order to equalize the potential of all constituent elements, using 1.5 V bulbs, you should discharge all battery banks, then perform 5-6 full charge / discharge cycles, and only after that use a power tool.

Replacing battery cans

Most effective method battery repair is the replacement of worn-out cans with new cells. Why, before restoring the screwdriver battery, you should purchase the required items, taking into account the technical and overall characteristics of the donors (they must be identical).

The very replacement of failed nodes does not cause any particular difficulties and involves the use of a soldering iron and materials for soldering (tin and alcohol flux on rosin). Moreover, in order to ensure the full operation of the battery in the process of performing work, it is advisable to adhere to the following recommendations:

• As elements for serial connection of cans, it is desirable to use existing plates, or use copper conductors with an appropriate cross section (due to high charging currents);
• To prevent jars from overheating (which can lead to breakage), soldering should be done quickly;
• The battery connection diagram must be consistent, and therefore the minus of each previous battery must be connected to the plus of the next.

The final part of the work should be the equalization of the potentials of all components that make up the battery. Why is it necessary to perform a full discharge cycle - charge the battery, and after cooling, repeat these steps at least twice.

There comes a time when a reliable home assistant - a screwdriver - stops working. Batteries are out of order, and regular recharging no longer helps. Do not rush to buy new batteries, there is another way out of the situation.

Cordless screwdriver - what power sources are used?

The cost of batteries is about 70% of the price of a new tool, so it is logical to try to repair the battery of a screwdriver. Before proceeding with the operation, you should familiarize yourself with the features of the voltage sources, find out what type of battery is used on your tool. Their structure is absolutely the same and does not depend on the country of manufacture and brand. Inside the plastic box are series-connected elements standard size. On each element there is an indication of the type and capacity in ampere-hours (A / h).

Screwdriver battery

Batteries are equipped with elements of the following types:

• lithium-ion (Li-Ion) - with an element voltage of 3.6 V;
• nickel-cadmium (Ni-Cd) - 1.25 V per element;
• nickel-metal hydride (Ni-Mh) - 1.2 V.

Evaluating lithium-ion power supplies in terms of quality and service life sets them apart from the competition. They practically do not lend themselves to self-discharge, high capacity, they can be recharged many times, several times more than other types of batteries. The cell voltage is three times higher than that of other types, which allows you to complete batteries with fewer cans, reducing weight and dimensions. They do not have a memory effect, which makes them an ideal device of this kind.

But there is no ideal in nature, and lithium-ion power sources also have some drawbacks. They cannot be used for sub-zero temperatures, which manufacturers honestly say. But practical use revealed another drawback: when the operational life of such a battery ends (three years), lithium decomposes, no means of making a reverse reaction bring results. The price of such batteries is three times higher than other power sources for a screwdriver.

Nickel-cadmium batteries are the most common due to their low cost. They are not afraid of negative temperatures, like lithium-ion voltage sources. If a screwdriver is rarely used, such elements are ideal, because they can be stored discharged for a long time, while maintaining their characteristics. Such batteries have a lot of disadvantages: they are of small capacity, toxic, so their production is concentrated in underdeveloped countries. The tendency to self-discharge, short life expectancy with intensive use - also belong to the disadvantages of these batteries.

Nickel-cadmium batteries dry out at the end of their useful life. Those who know about this feature refill them, but this operation is not easy to perform, so few decide on such an action, preferring to replace individual battery banks. If the cause of failure is the memory effect, which is considered a big disadvantage of nickel-cadmium batteries, it is possible to restore their performance by flashing.

Nickel-metal hydride batteries are environmentally friendly, high quality, produced by the world's leading companies. Compared to Ni-Cd, they have clear advantages:

• slow self-discharge;
• the memory effect is small;
• resistant to multiple discharge-charge cycles;
• relatively large capacity.

But during long-term storage without work, some of the characteristics are lost, they do not like low temperatures Plus, they cost a lot. And the main disadvantage is that they cannot be repaired.

We determine the malfunction - is it repairable?

If you have elements installed on the screwdriver in the battery that, in principle, can be repaired (except for nickel-metal hydride), we proceed to disassemble the case. It has two parts connected with screws or glue. In the first case, no difficulties are foreseen - we unscrew the screws and separate the parts. If the connection is glued, we insert a knife between the parts at the junction, then we screw a self-tapping screw into this place. Carefully, so as not to damage the elements, we pass the knife along the joint, separating the parts of the case.

We check the elements on a fully charged battery.

Having disassembled the case, we will see banks connected in series, which means that a malfunction of even one bank can lead to bad job battery. The main task during the repair is to find a weak point in the circuit. We remove the cells from the body and lay them out on the table so that there is convenient access to all contacts. With a multimeter, we measure the voltage of each element, write down the indicators on paper or directly on the case. The voltage indicator on a nickel-cadmium battery should be 1.2-1.4 V, on a lithium-ion battery - 3.6-3.8 V.

Types of malfunctions and methods for their elimination

Having measured the voltage, we assemble the cans into the case, turn on the screwdriver and work until it loses power. Again, we disassemble and re-take the voltage indicators, again we fix. Cells with the lowest voltage, once fully charged, will again show a significant drop in voltage. A difference of 0.5–0.7 V is considered significant. Such elements will soon become completely unusable, they are candidates for resuscitation or complete amputation.

If you have a 12-volt tool, you can use more than one tool to troubleshoot the problem. simple method, excluding double disassembly-assembly. First, we also measure the voltage of each fully charged element, fix the indicators. We connect the load to the banks laid out on the table - a 12 V light bulb, which will discharge the battery. Next, we are again interested in voltage. Where there is the strongest drop - a weak area.

Changing elements is the most reliable way

You will either need cans from an old battery, in which serviceable elements remain, or you will have to buy new ones, they are inexpensive. When buying, pay attention to the dimensions and capacity - they must match the existing elements. We throw out the bad cans, solder new ones in their place. It is desirable to connect using native plates or copper ones that are suitable in size. Compliance with the cross section is important - when charging, a large current passes through the contacts. If the area is insufficient, they heat up, the protection works.

We pay special attention to the connection sequence - the minus of one can is connected to the plus of the other.

On the assembled battery, we equalize the potentials, since they are different. We put on charging for the whole night, let the battery rest for a day, then measure the voltage. Ideally, all elements should have the same indicator. We turn to the discharge of the battery until it is completely depleted. We repeat the procedure twice more. It should be said that such training is necessary not only for repairs, it should be carried out every three months in order to extend the life of the battery.

Restoring capacity - flashing batteries

A method acceptable for nickel-cadmium batteries when the cells are not dry. You can verify this using the method below, if it does not help, then the electrolyte has boiled away. The essence of the method is in charging using high current and voltage. You will need a charger with the ability to regulate, charging for car batteries is suitable. We will charge each element separately, for which we remove the battery from the case and disconnect the banks from one another.

We set up charging for a voltage three times the nominal - 3.6 V. We connect to charger and turn on for 3-5 seconds. If the voltage test with a multimeter showed 1.4 V or a little lower, everything is in order. We collect the battery and use it. The method relieves batteries from the memory effect. It is not suitable for completely dead cans.

Battery resuscitation - proven in practice

As already noted, the main reason for the failure of nickel-cadmium batteries is the drying of the cans. The procedure for topping them up is not very pleasant, but not so complicated that it cannot be performed. We do everything, as always - we disassemble the case, take out the elements. We remove the paper with which the banks are wrapped. From some it is removed easily, whole, on some it has to be cut. We examine the body of the cells - some without any signs of corrosion, others can be seriously damaged, but the main thing is that the shell is intact.

With a thin drill at the top of the element, where there is a recess in a circle, we make a hole. You will need distilled water. We draw it into a syringe, insert the needle into the hole and pump water very slowly. It is not known how much it will enter, it is impossible to determine visually. If liquid flows from the can from the very beginning of water input, throw it away, it cannot be resuscitated, it is necessary to replace it with a new element. Some kind of reaction occurs there, which indicates the unsuitability of this element for repair. But this happens very rarely. Further procedures are usual - assembly, several charge-discharge cycles.

Lithium-ion batteries can also be recycled, but this operation is unhealthy due to the toxicity of the contents. The reason for their failure is most often a violation of the contact between the internal filling and the exit to the case. To check the suitability for repair, insert an awl into the hole at the top of the element so that it touches the inside. We connect a multimeter and look at the readings. If there is current, the reason is a broken contact, you can continue the repair.

With wire cutters we cut off a part of the metal on the cover protruding from the top of the element. We bend it upwards, and opposite the body metal we press it so that it touches the inside of the element. Now comes the turn of the most critical part of the operation - soldering. We use solder that has a flux inside, it is faster and more convenient to solder with it, especially in such a situation. We solder quickly so as not to overheat the element. If you don’t know how to do this, don’t take it - in this situation you won’t learn, but ruin everything. Then we close the gap in the case with sealant - and for charging.

It's real if you use one of the above methods!

Those of us who use a tool like cordless screwdriver, must remember that at some point the battery that ensures its operation may become unusable. And in this case we are not talking about discharge, but about the loss of its qualitative characteristics, as a result of which you will have to think about replacing, and this will require large expenses from the owner.

Once in such a situation, the consumer may consider purchasing a new screwdriver, which will be more simple solution problems than equipping old tools with new batteries. However, in such a difficult situation, a solution can be found. In the event that the screwdriver uses certain type power supply, you can try to restore the battery.

In terms of performance, repairing batteries for a screwdriver looks like a fairly simple task, so even if nothing works out for you, this will not lead to any serious consequences or costs for you. Next, the most important points regarding do-it-yourself screwdriver battery repair will be covered in detail.

Do-it-yourself screwdriver battery repair: which batteries need to be repaired

as a power source in models of screwdrivers produced today one of the following types of batteries can be used:

• nickel-cadmium batteries;
• nickel-metal hydride batteries;
• lithium-ion batteries.

Moreover, each of these power sources has its own characteristics.

Li-ion

If we evaluate these batteries by such characteristics as workmanship and service life, then lithium-ion batteries are out of competition. Due to their lack of memory effect, they can be considered practically ideal option such a power source, however, it is necessary to mention that they have such a minus as the impossibility of their operation at low temperatures.

It is with such a statement that manufacturers of such batteries come forward, although in reality they have other Negative consequences. For example, when such a battery loses its service life, then lithium decomposes in them, and this reaction cannot be influenced in any way.

Nickel-cadmium

These batteries differ from the previous ones in the sense that at the moment when their expiration date ends, they dry up. Therefore, those owners who know how to deal with such batteries in a similar condition, they are just reloaded. However, this is not so easy to do, and therefore there are very few people who decide to take such a step.

After all, there is a less costly solution to the problem, which consists in placing new cans for the battery of a screwdriver into the battery. In some situations, when the cause of the problem is the memory effect, which is usually considered one of the significant disadvantages of nickel-cadmium electrical capacities, you can solve the problem of restoring their performance by flashing.

Nickel metal hydride

As for nickel-metal hydride batteries, nothing can be done about them when they use up their service life. In such situations, home master there is only one way out - to look for a replacement for this battery.

If, in the event of a screwdriver battery failure, we consider the option of replacing the power source, then such a solution would be appropriate, regardless of the type of battery that the screwdriver is equipped with. At the moment, the network can find a lot of stores offering each user to buy quite affordable prices any type of battery, including lithium-ion, nickel-cadmium power supplies. True, in this case, the buyer will have to be prepared for the fact that he will have to install this power source himself.

First you have to disassemble the battery for constituent elements, put in place of the failed working stuffing, after which the assembly process is carried out in reverse order. It is this procedure that will be given further attention, but first it will be useful to consider the operation to restore nickel-cadmium batteries.

How to restore the battery capacity of a screwdriver: flashing nickel-cadmium batteries

It makes sense to use this method only when the most unpleasant thing has not happened to the power source - its drying out. If all the signs of this phenomenon are present, then it remains only to throw it away. Understand, What is the state of the electrolyte in these batteries?, you can conduct such an experiment with them: if after charging they also do not show signs of life, then we can conclude that the elements are dry.

If you managed to restore the battery to working capacity, then this will be a great success for you. If we talk in more detail about the technology for solving this issue, then restoring the battery of a screwdriver is to act on its elements with the help of current and voltage of a significant rating.

Sometimes, after repeated charging carried out in relation to certain elements, the desired result cannot be achieved. In this case, they will only be thrown away. We will have to replace the elements that have become unusable with working batteries. I would like to repeat once again that the described method is effective in combating the memory effect that nickel-cadmium batteries have. If the battery has exhausted its resource, then this method will be ineffective.

Replacing the battery in a screwdriver: we determine and change the used capacities

The most common difficulties that arise during the repair of a screwdriver battery are as follows: it is important to open the batteries in such a way as not to damage them.

As a rule, manufacturers provide for this possibility, and therefore trying to seal their batteries tightly in order to avoid situations in which craftsmen try to repair the screwdriver battery on their own. Thus, they force the owners to abandon such an idea and force them to visit the store to buy a new battery.

In principle, this is not surprising, because companies pursue their own goals. However, even in this case, a solution can be found. But immediately you need to be prepared for the fact that the repair will take some time. However, if you are willing to spend your personal hours on such work, it means that by following all the recommendations, you will achieve your goal and be satisfied with the operations performed.

In the process of doing this work, you should be aware of certain nuances - without them it will be difficult for you to correctly assemble the elements into a single battery. During the factory assembly, the plates with which the elements are connected are not soldered. For these purposes, spot welding is used. Since you don’t have such an opportunity, you will have to spend time soldering, using a regular soldering iron for this.

During this operation, keep in mind that the state of the elements overheating can have a negative effect which should not be allowed. Also important point is that each element has a similar capacitance, as well as an output voltage.

You should also dwell on the overclocking of a new battery. It is necessary to resort to this procedure when you have already been able to reflash the old elements. A similar procedure is recommended for nickel-cadmium batteries, which should be carried out every 6 months. The main thing that this procedure allows you to achieve is to ensure maximum battery charging and subsequent full discharge. This work must be carried out in two steps, and even better in three.

The state of most nickel-cadmium batteries is adversely affected by their repeated charging, carried out without first discharging. If we neglect this recommendation, then this can lead to memory effect. Its essence can be described as follows: the place from which they began to carry out their exercises, they begin to be considered as a starting point.

Conclusion

If in the process of using a screwdriver you find that its battery has exhausted its entire working life, then you should not prepare to buy a new device. If you find yourself in a similar situation, you can try to restore its performance. There are many ways to estimate the odds successful repair, after which it is already possible to proceed with the implementation of the plan. In some situations, this approach allows you to save a lot of money and continue to perform the necessary operations on the same day.
