One measure of power is watts, and watts is amps x volts. So amperage
is only current. It's not a measure of power until the voltage is
factored in.

at 13.5 per cell. So if it is a 10 cell 1.2v pack 12v is dead.and drill

I agree with George. The charging voltage when the engine is running
is I think 13.4, but the fully charged battery I've always figured at
12.6v. That's, 2.1 volts for each cell.

battry charged and it will work fine. The original battery operated
drill had a separate pack, A fuse wont be necessary except for shorted
wiring. You could probably run it at 16 v or more. and not hurt
anything.
