<p>A battery charger (12) accepts battery packs (14, 116,18) of several configurations and size (number of cells). The common feature of the battery packs (14,16,18) is (at least) one cell (124, 124c) housed on end and substantially coaxial with a specific terminal block (22, 22a). Terminal pins (158, 160: 248, 250) are shielded from external contact and engage the terminal blades (90) of a charger terminal assembly (88) on the floor (46) of a receptacle (20). Charger terminal assembly (88) is at one end of the receptacle (20) which is elongated so that it can accommodate a battery pack "nose" portion (130, 242, 180) with either one or two cells (124, 124c) housed on end and side-by-side. Upright side walls (36, 37) of the receptacle (20) support the battery pack (14, 16, 18). In the battery pack portion (136, 170, 182) outside the receptacle (20), cells (124, 124c) may be arranged in any configuration to suit tool or other requirements. <IMAGE></p> |
