Zusammenfassung:	A battery pack is described. The battery pack includes a DC to DC converter and a group of at least two primary cells. The DC-DC converter is operatively coupled to the group of primary cells. The group of primary cells have an initial voltage that is higher than a rated voltage for the battery pack. The DC-DC converter converts the voltage to a regulated nominal voltage that is lower that the rated voltage of the group of primary cells. By regulating the battery voltage down to a constant voltage, the cells can discharge down to a minimum voltage level per cell enabling additional energy transfer from the group of cells.
