One of the problems that occurs frequently in electrical devices is the battery life, either because it is damaged or because you have the equipment for a long time, in the end you end up discarding it because the replacement is usually more expensive than the equipment itself, but there are several ways to reuse these products. 

Do not discard any electronic device, reuse it!

After you have purchased the best screwdriver ( if you click here, you find several products to choose from ) bdel moment or any other model, but a few months or years pass and the battery is damaged, by that time maybe the product is not under warranty, So you have to look for the spare part in various stores or in e-commerce pages and observe that the spare part, specifically the battery, has a much higher value than buying the new product. Therefore, you think you should acquire a different brand and discard the old one, but this does not have to be that way, since there is a way to reuse it without having to make a new investment.

Many users have had problems with the battery of the screwdriver that they have used constantly, which runs out of its useful life, either because it has been years after the purchase, due to overheating or exhaustive use. Since, the product was purchased for small DIY work, but it was used even in its work in a very frequent way, which ended up shortening the battery’s useful time, (in extreme cases it also affects the engine components). 

 

Check equipment damage

If you have not discarded your cordless electric screwdriver that suddenly stopped working, we invite you to evaluate the problem. That is, if using the equipment stops working there can be many factors, but if you stop charging the battery for 2 hours and when you put it back to the screwdriver it does not turn on, it means that the problem is the battery. 

Now we are going to provide you with two options so that you can use your screwdriver again, one of them is using a charger of the same battery voltage and the other one using the equipment with a cable system, but you have to follow the steps that we will indicate to you Letter to avoid accidents.

Relive the battery using a charger 

For this option you will need to have a digital multimeter on hand, with it you must identify the positive and the negative of the battery. Using alligator clips or chopsticks, first place the one with the black color on one of the battery contacts and the red one on the other end. If negative numbers are shown on the digital multimeter, the contacts are reversed, so you must perform the same procedure, but in an inverted manner. That is, in the contact you placed the color red will go black and vice versa. Now, mark a positive (+) and negative (-) sign on the side of the battery contact with a marker so you avoid performing the same procedure.

Once you have completed the previous step, you will need to verify the battery charge voltage. Display the energy efficiency label on the back of the battery and find a car battery charger that can provide exactly the same power. Then, using crocodile tweezers or chopsticks you will have to give the battery a few touches; Remember that red is positive and black is negative.

Place the clamps and hold them for 10 seconds and remove them immediately to check the heating of the battery. In addition, it should be noted that, this process should be done 3 times, but always checking on the back with your hands that the battery does not overheat at more than the ambient temperature. 

Reuse the screwdriver with a wired system

If the previous step has not worked for you, we have this alternative to prevent you from throwing away your screwdriver. Now, you will have to use the digital multimeter to identify the positive and negative contact of the screwdriver as we mentioned earlier in the process of reviving the battery. Remember that negative values ​​will indicate that they are reversed; mark them also with a black marker.

Then, use the car charger that has the same battery voltage so you can perform the function test. Place the red clamp on the positive contact and the black one on the negative, press the trigger of the drill and verify its functionality. 

Now, you have to look for a power supply so that you connect it to the screwdriver in a fixed way, for greater ease you can acquire an economical one in an e-commerce store or page, but taking into account that the voltage should not be different from that of the drill, either 4, 8, 12, 14, 16 volts, etc. In addition, the red and black cables that you will use for permanent mounting must be 1.5 mm to 2 mm thick, as well as these must not exceed 2 meters to avoid overheating or voltage drops.

Now, install the red in the positive contact and the black in the negative, use black insulating tape to permanently place them in the contacts and press with some plastic object that does not work, you can use the same battery case, but empty, without contacts that may affect the operation of the equipment. That is, you will only need something that puts pressure to prevent movement of the cables. With the same insulating tape make small folds in both cables to form one and avoid getting entangled.

Now we go to the power supply, connect the black wire in the negative (-) and the red one in the positive (+). Now, before you start the screwdriver, use the multimeter to verify that the proper power is being transmitted according to the screwdriver voltage, since an excess could damage the device.
