A microprocessor controlled battery charger utilizes a high frequency switching circuit and a means to read the voltage of the battery plus a timer in the circuit wherein the microprocessor is connected both to the timer and to the voltage reading means and establishes a decreasing step charging rate of the battery so as to charge the battery at a first charging rate, then at a second lower charging rate until the rate of change of voltage with time is less than a small amount of volts per hour and then the current is reduced to a third charging rate for a finishing charge of the battery. In the preferred embodiment the first charging rate is maintained until a predetermined battery voltage is achieved and the third charging rate is maintained for a given period of time.
