I have two Porter Cable electric drills. One uses a 14 volt rechargeable
battery and the other a 12 volt. The 12 volt battery appears to work on
the 14 volt drill quite well. The question is - if I were to use it in
place the 14 would it damage the battery? The 14 is about shot.

Should be fine ... you already tried it. There will be a bit less torque
and power.




And more current. Thus more heat, both for the battery and the drill
motor. Might shorten life of both.
