The problem of battery failure due to failure of one cell in a rechargeable battery, and the related problem of inefficient use of a battery over its dynamic range due to differences between the performance of cells in a battery, are addressed by providing one or more capacitors selectively coupled to the various cells of the battery. The selective and repetitive coupling of capacitors to the cells permits balancing of charge among the cells. This minimizes the risk that any one cell would suffer catastrophic failure due to being fully charged or discharged prior to the other cells in the battery. This also permits making use of the battery over nearly all of its dynamic range. In this way, battery life is maximized.
