Abstract: PURPOSE:To keep the charging time constant even when the capacity of a lead storage battery differs by stopping charging when battery voltage reaches fixed voltage, reopening charging when battery voltage reaches specified voltage, adjusting charging currents and properly selecting charging voltage in response to the capacity of the lead storage battery. CONSTITUTION:An output from a comparator 21 is at a low level at the beginning of the start of charging, a storage battery 5 is supplied with charging currents I from a power circuit 1, and voltage at a high level is output from the comparator 21 and the supply of charging currents I from the power circuit 1 is stopped when the battery voltage V of the storage battery 5 reaches fixed voltage V1 for the time t1. When battery voltage V gradually lowers and reaches voltage V2, the output from the comparator 21 is changed from the high level to the low level, and the storage battery 5 is fed with charging currents I from the power circuit 1 again. The storage battery 5 is fully charged for the time t2 while such stoppage operation and supply operation are repeated. Voltage V2 at a time when the output from the comparator 21 is altered from the high level to the low level is selected on the basis of the magnitude of the capacity of the storage battery 5, and the time of the completion of charging can be equalized.
