I have a Makita cordless 18v drill (gift from family) that uses 18v Lithium Ion batter packs. Battery model BL1815. BTW, this is one of those 'quick charge' batteries that only require about
12 minutes.Short story. Battery fell into water during an outdoor plumbing repair. Recovered within 15 seconds. Battery charged OK 2 more times and now, upon trying to charge, is shown as "defective" by the intelligent? charger. It will not charge.
Took battery apart. Unlike older storage packs these batteries come apart by simply removing 4 screws. Inside is a small circuit board with many components, a battery pack and hint of silt from the dunking.
Any chance that this can be fixed somehow? It has only been cycled 5 times total. Son-in-law (who gave me the gift) simply says take it back, or, he will reverse charges on his AmEx credit card. I won't do this. This is simply not a manufacturer's defect.
All advice appreciated. Trying to save $ 65.
