ABSTRACT:
A consumer insertable battery pack assembly (70) comprises a plurality of substantially parallelipiped shaped rechargeable cells (61, 62, and 63) having a positive terminal (68) and a negative terminal (66). The positive terminal of one cell is coupled to the negative terminal of an adjacent cell. Insulation (17) is used on at least one of the terminals of the cells to offset the terminal location to prevent the charging of consumer insertable primary cells. The cells are within a housing (74) having contacts (76 and 86) for charging being arranged and constructed to mate with the offset terminals (68 and 66 respectively) of the cells. In this manner, the cells are unable to mate with the terminals of consumer inserted primary cells having centrally located terminals.
