Abstract
A battery charger, for preventing deterioration from the memory effect, that includes a switching circuit with first and second reference voltages. The second reference voltage is lower than the first reference voltage. The switching circuit forcibly discharges a battery where the voltage level corresponding to battery capacity is between the first and second reference voltages, and charges the battery after the battery capacity reaches the second reference voltage.
