Abstract

PURPOSE: To recover the capacity of an NiCd battery to a predetermined maximum capacity by discharging a used battery deeply again before it is recharged.
CONSTITUTION: Main section of a battery charger comprises a charge control circuit 1, a discharge control circuit 2, a charge/discharge switching control circuit 3, a switch 4, and an NiCd battery 7. When a used NiCd battery is charged, the charge/discharge switching control circuit 3 controls the switch 4 to connect the battery 7 with the discharge control circuit 2 thus charging the discharge control circuit 2 upto a predetermined voltage. Then the control circuit 3 controls the switch 4 to connect the battery 7 with the charge control circuit 1 thus charging the NiCd battery 7 and recoverying the capacity thereof upto the maximum level. By such arrangement, the NiCd battery can be used with optimal charge/discharge cycle and the battery performance can be fully exhibited.
