Abstract
A device that includes a plurality of substantially identical batteries coupled via switching circuits to a power bus is provided. Control circuits can be coupled to the batteries and the switching circuits to provide electrical energy to the bus from each of the batteries during a sequence of predetermined time intervals, wherein one of the batteries provides electrical energy to the bus during a greater percentage of each time intervals than the others of the plurality. The remaining battery life of the others of the plurality can be estimated in response to sensing that the one of the batteries is substantially discharged.
