Abstract
A system and method for charging a battery is provided. The method includes applying an excitation current pulse to the battery to determine the battery type and whether the battery is capable of holding a charge. To charge the battery, a series of current pulses are applied in groups with the average current being reduced for each succeeding group to take advantage of changing battery charge acceptance. When the voltage of the battery matches a predetermined value, application of the current pulse groups is ended. A single current pulse is then applied to complete the battery charge.
