Abstract
A battery charger for charging alkaline zinc/manganese dioxide cells is disclosed. The battery charger contains means for producing a direct current voltage at 25 degrees centigrade of from about 1.6 to about 1.7 volt as well as means for individually and independently limiting the voltage delivered by the battery charger to each of the cells. The charger also contains means for individually and independently limiting the current applied to each of said cells by said battery charger as well as means for individually and continuously varying the current applied to each of said cells. Once any of the cells in the charge has reached its desired voltage, the charger reduces the current supplied to said cell substantially to zero current.
