How to disassemble an electric screwdriver battery?

So, the first step is to take the battery and place it on a hard surface. Personally, the kitchen table came up to me, besides, in parallel with disassembling the battery, you can “grind off” something tasty.

Batteries on screwdrivers are collapsible, but they are not collapsible. It is clear that it is more profitable for the manufacturer to make non-collapsible ones, since the failure of the battery automatically implies the purchase of a new battery, only there is one small “НННООО”!

The thing is that the price of a new rechargeable battery for “Shurik” reaches one third of the cost of the electric screwdriver itself! Therefore, as a true patriot of our country and a level 80 handshake, I didn’t even have a thought about buying a new battery or some fucking Chinese analogue (sorry for my French).

An immediate decision was made. I will disassemble the battery of an electric screwdriver with my own hands.

How to correctly and quickly disassemble the battery of the Makita electric screwdriver

I hasten to share with you two interesting news that have not so sickly changed my way of life that has developed over the years:

On December 16, 2015 my son was born. Yaroslav :))) Now I have a daughter and two sons. 2. Shortly before the birth of his son, a terrible thing happened. the battery on the Makita electric screwdriver “died”, which had been plowed with faith and truth for almost five years 🙁

Of course, the first event is much more important for me, but I will introduce you to it in the next article of my blog 🙂

But the news that the battery of the electric screwdriver came to an end not sickly so undermined my already shaken health, since the “deceased” was immediately buried and a certain amount of alcohol was consumed for the repose of his 14-volt soul. Yes, if Megavolt will be with him.

Of course, for all the years of his construction and repair career, your humble servant has “shoved” a huge number of screwdrivers, but Makita has become a real godsend for me. Its ergomics, its reliability. I was captivated by it at first sight!

In general, I could not come to terms with the loss and decided at all costs to repair the battery of the electric screwdriver.

After reading a huge amount of literature, graduating with honors from the courses “Novice Warlock”. the department of applied necromancy, that is to say, the revival of the dead. I got down to work, but from the first steps I realized that in order to restore the battery of an electric screwdriver, it was necessary to disassemble it.

How to disassemble the battery of an electric screwdriver yourself?

We take the battery and begin to carefully cut it with an ordinary, but very sharp knife at the junction in the battery

Then, in order to tear off the layer of glue located lower, I scrolled along the entire length with a self-tapping screw. This must be done carefully, because the body may crack and then you will have to get a haircut as a monk 🙂

When you feel that the battery begins to “crunch”, you need to start tapping the joint with a flat screwdriver

So, my dear hands, I myself disassembled the battery of the Makita electric screwdriver. Of course, my method is not a panacea, but I know for sure that it works 🙂

Types of fasteners, preparation for work

The battery module can be fastened with:

  • glue;
  • latches;
  • screws.

It is not uncommon for a combination fastener to be used with the simultaneous use of different types of fasteners, such as screws and glue.

Before disassembling the battery from the Makita electric screwdriver, you should measure the voltage issued by the battery pack. This figure will help determine the number of faulty cans. After assembly, the measurement is carried out again, checking the correctness of the work done.

How to disassemble a battery from a Makita electric screwdriver

The battery for the Makita electric screwdriver is disassembled in order to replace one / several cans (batteries), or to transfer it to another type of nutrient elements. Work must be carried out with the utmost care, movements must be precise, careful so that the case, banks, electronic boards and wires are not damaged, and the module, after assembly, functioned properly and safely.

How to disassemble the battery of a Makita electric screwdriver 12 V, bonded with glue

The glue seam should be disconnected especially carefully so that cracks and splits do not appear on the plastic, and when assembled, the case completely covers all the electronic parts and ensures safety. To do this, it is rational to use a mallet with a rubber striker, or another hammer made of soft material.

Around the entire perimeter of the seam, blows are applied, applying medium force, ensuring that the gun slightly bounces off the body. The procedure is not short-term, it takes from 10 minutes. and more should be done without haste. In its course, the halves of the body are periodically slightly pulled away from each other, helping them to separate. The adhesive layer collapses with a characteristic sound, when specific clicks become more frequent, you can help the separation with a thin knife blade, or a similar tool, trying to open the seam with it.

Another way to gently unfasten the glued module is with a thin knife, flat screwdriver. It lasts a little longer, work must be done with caution, since the risk of injury and plastic cracking is very high. With a blade, carefully loosen the seam around the entire perimeter, then insert a screwdriver tip into it and slowly separate the halves of the module.

Before disassembling the battery of a 12 volt Makita electric screwdriver, you can warm up the glue layer using a construction hair dryer, which will speed up and facilitate the work. Having placed the battery module at a safe distance, a hot stream is directed to the connection, warming it up around the perimeter. When the glue softens, the case will be easy to open.

Important: gloves used during work will help avoid burns.

Connection with screws, latches

Loosening a screw fastener also requires care. Pick up a screwdriver with a suitable tip shape, rod length. They remember from which holes each screw was unscrewed, and during assembly they are screwed strictly into place. This must be done due to the fact that the hardware can be of different lengths. A short screw screwed into a deep hole will not be able to secure the connection, and a long screw placed in a short opening can pierce the wall of the case, power elements and even an electronic board. If, as a result, the electrolyte seeps out, the microcircuits, nearby banks will be damaged, and in case of unfavorable development of events, an explosion is possible.

The module, fastened with latches, is easy to open: you just need to find them and open them with moderate force. Most often, one latch is used, or two side.

How to disassemble the battery of a 12 volt Makita electric screwdriver

A little about how to convert a battery from cadmium to lithium and who needs it

Let’s talk about how to convert the battery yourself from one type of battery to another. There are many videos on this topic on the Internet, where a lot is said about what are the advantages of having lithium in the electric screwdriver. However, if you do not use the tool intensively and constantly, there is absolutely no point in a lithium battery. Lithium-ion batteries tend to “age” more quickly than cadmium, and simply do not have time to develop their resource under conditions if the tool is used from time to time.

Alteration of the battery of an electric screwdriver using lithium batteries may be necessary for professional craftsmen who use the tool on a daily basis and need powerful power sources. Of course, with a strong desire, you can re-solder the battery to lithium, but whether this is advisable is up to you. Read more about which batteries are best for an electric screwdriver →

Thus, you can not only disassemble the battery of any electric screwdriver, but also solder one of two bundles, which will last as long as possible, and you will not have to buy a new battery in the near future.

The work of a converted battery, provided that the cells are correctly soldered, will be no worse. The main thing is to treat the process with patience and maximum care, so that at the first experience, you will finish the job with minimal losses and solder everything correctly. If you manage to collect everything, this will become an additional incentive to continue your experiments in the field of electronics. Assemble the battery yourself once. and you can save money on buying new batteries for an electric screwdriver in the future.

How to disassemble and recycle your Makita electric screwdriver battery

Everyone understands that the battery of an electric screwdriver comes the moment it loses its former performance and needs to be replaced. Usually, only a couple of parts in a common bundle “sit down”, but this has a bad effect on the entire battery. Therefore, it is necessary either to replace several parts with new ones, or in spite of this, to change the battery pack completely. Since the complete set of any electric screwdriver. “Hitachi”, “Makita” and other models. includes two batteries, if there is a desire of course to try to assemble a whole homemade battery from 2. Owners of power tools who use them all the time, when they begin to wonder how to recycle the battery of an electric screwdriver to lithium. As for the beginners, who are concerned with this goal for the first time, they first have a question about how to disassemble the battery from the Makita electric screwdriver or others, so as not to destroy the fragile plastic box.

We measure the voltage

Before measuring the voltage of the parts, prepare an ordinary pencil with which you will begin to write down the value of U issued by each battery in the bundle. Since almost always “running” screwdrivers are equipped with nickel-cadmium batteries packed in dense layers of cardboard, it is essential to ensure that the batteries are accessible from both sides.

Now it remains to turn on the voltmeter (as it is also called the multimeter) and start measuring. When measuring, we make each battery an exposure for a period of 5 seconds and see if the voltage drops (usually it is normally about 1.2 volts for each battery separately). We fix the characteristics with a pencil. It is impossible to keep the probes on batteries for a long time, since the resistance increases, and there are variations that simply burn out.

As practice shows, one has only to fail one element of the entire bundle, this has a bad effect on the workplace of all batteries. If the voltage indicator on any “bank” is 1 volt or less, it has already exhausted its own resource. To be able to completely make sure here, you should check the self-discharge level of each battery in the bundle.

Repeated measurements are taken after 15 minutes. When measuring, be sure to check the primary characteristics of U with repeated ones. If it turns out that there are batteries, the voltage of which after the initial measurements dropped sharply during the second measurement, it means that their self-discharge is the highest, just these elements have already become completely unusable.

If the unwanted elements are “calculated”, we disconnect them from others using a scalpel, and in their place we put suitable batteries from a spare battery. So we redo the whole block, collecting one real from 2.

Disconnecting cans from the board

Using a drill with a disk nozzle, the cans are sawn off from the board. The connections of each contact with the controller are sequentially removed, and the elements are disconnected from the common frame.

It is necessary to do this quite carefully so as not to damage the board itself, but hard enough to completely disconnect.

How to disassemble a Makita electric screwdriver

In order to disassemble the Makita electric screwdriver, you must first disconnect the battery. Then, in the tool body, all the screws that hold the two halves together are unscrewed. After that, the body is removed, and all external components are opened in front of the master: motor, gearbox and switch. It is also worth noting that in such models, special plates are often installed that are responsible for switching modes. If the disassembly is not very careful, a small plate can simply not be noticed. After disassembly, you can immediately proceed with the repair of the corresponding part.

How to repair an electric screwdriver battery

Battery powered screwdrivers are also very susceptible to battery wear. This happens over time even with proper use. If you do not follow the rules of operation, the battery will no longer hold a charge very quickly. And in this situation there are two ways out: buy a new battery or try to repair the battery of the Makita electric screwdriver with your own hands.

The second option will require spending a certain amount of time and effort, and you also need special elements.

The battery of an electric screwdriver is a set of a number of special nutritional cans, which are soldered to the charging controller and make up an integral structure.

The corresponding nutrients can be found in power banks or laptops. There are also some such banks there. In laptops, 6 cans are usually used, and in power banks. 4. But the number may be different and depends on the capacity of the battery.

If the master has extra elements of such lithium batteries, then they can be used to repair the battery of an electric screwdriver.

How to repair a Makita electric screwdriver

One of the most common problems with a Makita electric screwdriver is first speed problems. At the same time, everything functions perfectly at second speed. This problem is associated with a malfunction of the tool reducer, which does not allow effective use of the first speed. Let’s consider how to get rid of this problem and repair the electric screwdriver.

Screwing in bolts instead of teeth

After all the gears are removed from the gearbox, the inside of the device will open to the eye. Given the specifics of the problem, most likely the master will see that all the plastic teeth on the inside have been ground off. This happens during long-term use of the device, or in case of gross violation of the rules of use. Plastic teeth are soft enough that they simply grind under the influence of temperature and constant mechanical stress. This leads to the fact that the main gear has nothing to catch on and it starts to scroll.

To repair and restore functionality, it is necessary to restore the teeth. In this case, there is no need to restore all the teeth, but it is enough to install two iron.

To accomplish what you want, you need a drill, small bolts and a drill. It is advisable to use a diamond-coated drill, since it will allow you to effectively grind off the excess part of the bolt in a relatively short time.

  • At the location of the plastic tooth, a hole is drilled in the side wall of the gearbox. Use a drill bit slightly smaller than the diameter of the bolt. So it will be possible to screw it in with effort and ensure a secure fit.
  • Two holes must be drilled diagonally to ensure a secure hold of the gearbox and stable tool performance. Thus, the load will be distributed over two teeth.
  • During drilling, it is advisable to direct the drill slightly downward so that later the bolt does not stick out upward. Otherwise, it will take much longer to process it with a drill.
  • Now you need to forcefully screw the bolts into the holes obtained.

After carrying out all these manipulations, the tooth blanks will be ready. Now you need to properly process them and give them the appropriate shape. This is done with a drill.
