My BL1850B battery has been at the bottom of the harbor for a few hours. I used a magnet to retrieve the DDF484 drill from underwater. I let the battery drain and opened it up. All the water is now out, but the lights are also alternating in pairs. I opened the battery. The voltage across the cells is 19 volts. The cells seem to be fine. Is it possible to reset the circuit board? (By the way, the DDF484 works again after disassembly and cleaning.)
