Recently I was using a Ryobi cordless drill to work on some drainage equipment. Unfortunately it caused a spill and a little water got on me and the drill. I did not think it was a lot of water (and I thought the battery had stayed dry), but after that the drill's battery stopped working. When I place it on the charger, the charger says that the battery is fully charged, but the battery's power indicator button doesn't cause it to light up and I can't get it to run a flashlight.
Is the battery kaput? Or is there something I can do to salvage it?
