1. A method of controlling a charging of a lead-acid battery by adjusting a charging voltage in accordance with periodic voltage sweeps which comprises detecting the voltage of the battery being charged, lowering the voltage being applied to the battery until a minimum acceptable level of current is detected, initiating a voltage sweep over a predetermined range at an augmented voltage rate with time, detecting whether a maximum current for a charger power supply has been reached, setting the charging voltage at that point if the maximum current has been reached and stopping the voltage sweep at that point, continuing the voltage sweep when the charger current has not been maximized, determining voltage and current values at intervals during the voltage sweep, selecting the charging voltage based upon the current-voltage values determined, terminating the voltage sweep, delaying for a predetermined period of time and thereafter initiating a further voltage sweep.
