18 volts on a 14 volt drill

Plowboy · 03-02-08, 12:38 PM

What problems might I encounter by running a 14.6 volt drill on 18 volt batteries.

Very little actually. I have a 9.6 volt drill that I run on 12v - works fine. I think high loads a long trigger time u may find over heating.

Assuming you can get the battery connected properly to the drill, df hit on the main problem. The battery would be pushing higher-than-rated voltage through the motor during any high demand times. I think it would be easy to kill the motor if'n you didn't pay extra special attention. That's just me bench racing, though. I've never done it. I have however, seen how quickly headlights fry during unregulated alternator output. (hint: in about the time it took to read that sentence)
