Abstract
A battery charging system designed to charge a battery, especially a nickel-cadmium (Ni-Cd) battery from a lead acid power supply without overcharging, and to charge uniformly a plurality of batteries in parallel. A non-linear resistance is utilized and is matched to the voltage difference of the power supply battery and the batteries being charged.
