Abstract
A battery charger for charging primary alkaline zinc/manganese dioxide cells. The battery charger with circuitry for producing a direct current voltage at a temperature of 25 degrees centigrade of from about 1.6 to about 1.7 volts and individually and independently limiting the voltage delivered by the battery charger to each of the cells. The charger also contains circuitry for individually and independently limiting the current applied to each of said cells by said battery charger and 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.
