Abstract
A method of reconditioning a battery having a plurality of cells in a plurality of packs comprises electrically connecting the plurality of packs in series. A selected pack for reconditioning is electrically isolated from the remaining packs. A current produced by the battery is bypassed around the pack to be reconditioned by a bypass circuit. The selected pack is discharged. While being discharged, the current produced by the remaining battery is passed to an electrical load. Upon discharging, the selected pack is recharged.
