lost charger 18 volt cordless drill?

can I use a 12 volt battery charger to charge an 18 volt drill battery?

You need a charger that does the same voltage and chemistry of battery. You also have to find out where the thermistor hooks up.

No, sorry. Drill chargers are designed for a specific voltage. The 12v charger would probably not work at all, or to not overcharge (destroy) your battery if it did work.
