Abstract
This method of charging includes a method of terminating charge when three events have occurred: a voltage across at least one of the cells reaches a predetermined maximum voltage, the average charging current falls below a predetermined minimum current, and the presence of a power source has been detected. The method also includes a safety termination that prohibits charge upon the expiration of a timer when the cells have stored little or no energy.
