In discharging a nickel- cadmium battery 1 with serially interconnected cells 9, all of the cells are bridged over almost simultaneously by respective discharge resistors (40), (Fig. 2), each having a resistance value preventing the exceeding of the maximum discharge current. Contact elements (31), (32) are mounted in bores in a carrier plate 22 so as to be aligned with a corresponding pole (6), (7) of a cell when the plate is positioned over the battery. A respective discharge resistor (40) is connected between each pair of elements (31), (32) associated with a corresponding cell 9. Contacts (34), (35) of the elements are spring biased towards the cell poles, and incandescent lamps 47 or LEDs connected between corresponding pairs of elements (31), (32) can be used to indicate that the contacts (34), (35) are engaged with the cell poles. <IMAGE> |
