2106980 9315544 PCTABS00024 A battery charger (10) for charging primary alkaline zinc/manganese dioxide cells is disclosed. The battery charger contains a transformer (18) and diodes (20 and 22) for producing a direct voltage at 25 degrees centigrade of from 1.6 volts to 1.7 volts as well as comparator (34 and 36) and a reference voltage network (46-68) for individually and independently limiting the voltage delivered by the battery charger to each of the cells. The charger also contains circuitry (96 and 98) for individually and independently limiting and varying the current applied to each of said cells. Once one of the cells in the charger has reached its desired voltage, the charger reduces the current supplied to the cell substantially to zero current.
