“So, your power drill battery dies. What now? Fork over 85 bucks for a new one? I don’t think so. After searching high and low on the internet for a good price for a replacment battery I found the retail for my Black & Decker 14.4V to range from 35-85 dollars. Riiiight. Time to make your own!”Link.

  1. Weird, I did almost the exact same thing last weekend for my Black and Decker drill :0. Refreshed both my dead nicad packs.

    I started with pre-made drill packs from harbor freight (item 90712). Disassembled them and had to rewire 3 or 4 cells to fit the same form-factor. I just cut the battery straps in the middle and re-soldered them in their new locations. Re-used the B&D case and connector.

    The replacements are 1000mAh nicad cells, and are lighter than the original so I assume they are smaller capacity (forgot to check the bottom of the B&D firestorm pack). But for $12.50 for 2 packs (on sale), I couldn’t go wrong!
