A system for sequentially charging a plurality of batteries initially interrogates each battery to determine the battery type and the level of charge. The charging system prioritizes the batteries to be charged from most to least fully charged and charges the batteries in that order. The charging is provided by pulsed current during sequential portions of periodic intervals to charge the batteries in a short period of time and utilize the battery charger to full or nearly full capacity.
