Apparatus for charging alkaline zinc-manganese dioxide cells
First Claim
1. A battery charger for charging primary alkaline zinc/manganese dioxide cells and for applying current to said cells, wherein said battery charger comprises:
- (a) means for producing a direct current voltage of from about 1.6 to about 1.7 volts when said charger is at a temperature of 25 degrees centigrade;
(b) means for individually and independently limiting the voltage delivered by said battery charger to each of said cells to a cell voltage of from about 1.6 to about 1.7 volts when each of said cells is measured at a temperature of 25 degrees centigrade;
(c) means for individually and independently limiting said current applied to each of said cells by said battery charger;
(d) means for individually and continuously varying said current applied to each of said cells by said battery charger, wherein, during a portion of the time each of said cells has said current applied to it, the current supplied to any one of said cells differs from the current supplied to any other of said cells; and
(f) means for reducing the current applied to any of said cells when said cells have reached a cell voltage which is substantially equal to said direct current voltage.

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.
