Abstract
A system for, and method of, calculating a capacity of a rechargeable battery having an initial terminal voltage and a battery power supply incorporating the system or the method. In one embodiment, the system includes: (1) a dummy load couplable to the battery to initiate a battery discharge cycle of a given discharge rate and (2) a controller, coupled to the dummy load, that periodically collects, and generates an accumulation of, terminal voltage samples during the battery discharge cycle until the terminal voltage reaches a predefined terminating level, the capacity being a function of a magnitude of the accumulation.
