Charging a 12v in an 18 volt charger will not hurt the 12v battery if it is a modern peak charger as most good chargers are. Peak is detected by Voltage drop of cells. RC chargers can , depending on model charge 4- 16 cells, voltage is the same it is amps that control rate of charge. Now if you charge a 18v pack in a 12 v charger it will never charge fully. Another way of finding peak charge is when the pack just Starts to get warm. A warm pack means electrical energy is being converted to heat, a bad thing to do to cells. Unfortunatly heat can be generated by the charger itself so voltage drop method is more accurate. They will not blow up or catch fire overcharged , they just loose alot of their life, they cook.

Well, if you get a dewalt cordless drill, and then build an adaptor for it, to run on house power. Havn't you just reinvented the electric plug in drill?

Nevermind all this wussy stuff. I put a #2 phillips tip on my 10 CFM air ratchet, wtih 400 foot pounds of torque, and 200 blows per minute.
(OK, well, I didn't do any of this, but it's fun to think about).

Play it backwards at that speed.
Tune in, turn on and drop out.
Stone (No D on the end of that) Well, on second thought.
