Abstract
The battery charger includes a slope detector which responds to the battery voltage of the battery being charged, to generate a peak indicating signal, when the voltage decreases following the peak charging voltage of the battery. A peak hold device responds to the peak indicating signal to cause the charger to switch abruptly from a high charge mode to a low trickle charge mode.
