Finding Max 18 volt charger?
18 volt battery charger will give out 20 to 22 volts. and drop off while charging. to around 19 volts. its just finding the right amps. as this is the most important part. these can very from 3 to 20 amps. some cheap chargers are 1 or 2 amps and can take up to 8 hrs to charge a battery. as an even a charger that says 18 volts at 8 amps or 6 amps should be fine. really depends on the manufacture setup.
