How to fixing your Cordless BOSCH Power Tools Battery

1.Identify the positive and negative posts on the Cordless Power Tools Battery with a volt meter, and use a piece of tape to label the posts accordingly.

2.Open the Cordless BOSCH Power Tools Battery case by removing the screws on the outside of the battery case with a Phillips head screwdriver. Organize the screws and any springs or additional items that fall out of the case in a small container.

3.Remove the Cordless BOSCH Power Tools Battery cells from inside the case by pulling up on them with your hand. Use gloves when touching the battery cells to avoid harming your skin.

4.Wrap the metal band that lies beneath the Cordless Power Tools Battery cells you removed with electrical tape. Avoid touching this metallic piece with your bare hands because it can get quite hot.

5.Remove the silver piece of insulation from the case and any plastic wrap that is covering the top and bottom posts on the battery.

6.Test the Cordless BOSCH Power Tools Battery cells with a battery tester, and mark those cells that are not working with a piece of tape so you can repair them later.

7.Choose one of the battery cells that you marked with tape in the previous step to be repaired. Locate the positive and negative ends of the cell, which can be identified by their flat or raised surfaces, respectively.

8.Touch the black clamp on the 12-volt power source to the negative end of the cell while touching the red clamp to the positive end. Hold the two clamps in contact with the ends of the battery for no more than two seconds, and remove them.

9.Test the cell again with the BOSCH Power Tools Battery tester to verify that the cell has been repaired and will take a charge. If the cell still does not take a charge, repeat step 8 for a maximum of 10 times until the battery holds a charge. If the cell will not hold a charge after 10 attempts, it will have to be replaced entirely
