How long to charge airsoft battery?
To figure out how long to charge a battery for:
(battery capacity (battery's mAh rating)/charger output (mA)) x 1.4(for NiCad batteries, 1.5 for NiMh batteries) = time (in hours).
For example:
I have an 1100 mAh battery and a charger which outputs at 300mA (it should be written somewhere on the charger -Output= X mA - or something like that). It's a NiMh battery so you multiply by 1.5.
(1100/300) x 1.5 = 5.3 hours
Therefore 5.3 hours = 5 hours and 30 mins.
