Battery-Free Drill Driver – Don’t Throw It Away, Reuse It With This Method

One of the problems that frequently occurs in electrical devices is the life of the battery, 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 dispose of any electronic device, reuse it!
After you have purchased the best screwdriver ( if you click here, you will find several products to choose from ) of the moment or any other model, but a few months or years pass and the battery is damaged, and by that time the product may not be under warranty, So you have to look for the replacement in various stores or on e-commerce pages and you see that the replacement, specifically the battery, has a much higher value than buying the new product. Therefore, you think that you should buy a different brand and discard the old one, but this does not have to be the case, 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 is running out of its useful life, either because it has been years after purchase, overheating or extensive use. Since, the product was bought for small DIY tasks, but it was used even in his work in a very frequent way, which ended up shortening the useful time of the battery, (in extreme cases it also affects the engine components).

Check equipment damage

If you have not yet disposed of your cordless electric screwdriver that suddenly stopped working, we invite you to evaluate the problem. That is, if when using the equipment it stops working there can be many factors, but if you leave the battery charging for 2 hours and when you put it back in 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 using the equipment with a cable system, but you have to follow the steps that we will indicate to the verbatim to avoid accidents.

Revive the battery using a charger

For this option you will need to have a digital multimeter on hand, with it you will have to identify the positive and negative of the battery. Using the alligator clips or toothpicks, first locate 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 carry out the same procedure, but reversed. That is, in the contact that you placed the color red will go black and vice versa. Now, mark with a marker a positive (+) and negative (-) sign next to the battery contact so that you avoid doing the same procedure.

Once the previous step has been completed, you will need to check the battery charging voltage. Look at the back of the battery for the energy efficiency label and find a car battery charger that can provide exactly the same power. Then, using crocodile clips or toothpicks, you will have to tap the drums; remember that red is positive and black is negative.

Attach the tweezers 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 must be done 3 times, but always checking on the back with your hands that the battery does not overheat to more than room temperature.

Reuse the screwdriver with a wired system

If the previous step has not worked for you, we have this other alternative to prevent you from discarding 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 inverted; Also mark them with a black marker.

Then use the car charger that has the same voltage as the battery so that you can perform the test run. 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 can connect it to the screwdriver in a fixed way, for greater ease you can buy an inexpensive one in a store or e-commerce page, but taking into account that the voltage should not be different from that of the drill, be it 4, 8, 12, 14, 16 volts, etc. In addition to this, the red and black cables that you will use for permanent mounting should be 1.5 mm to 2 mm thick, as well as these should 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 on the contacts and press with some plastic object that does not work, you can use the same battery housing, but empty, No contacts that could affect the operation of the equipment. That is, you will only need something that makes pressure to avoid movement of the cables. With the same electrical tape, make small folds in both cables to form one and avoid tangling.

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