Below are battery rebuild cores for you to rebuild your own power tool battery packs. With this purchase you will need to disassemble your case and solder your existing connector/sensors to our pre-assembled battery pack. We provide you with all the cells and tabs welded together.

Due to the current conditions of our lawsuit happy society we are unable to provide any instruction on how to assemble/disassemble your own battery other than what is listed below. If you cannot rebuild it yourself without further instruction please purchase a rebuild service. Unfortunately it only takes a few to ruin it for everyone :(

Click on the voltage/chemistry below that you would like. Once you add the desired items/quantities to your cart.
Specify the (Make & Model) number of your battery in the text box in your shopping cart. Specifying the brand and voltage is not enough.

DO NOT SPECIFY YOUR TOOL/CHARGER MODEL NUMBERS!
