Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a storage battery discharge controller that can efficiently use power of a storage battery, and to efficiently use power of a group of storage batteries, even if power failure occurs during testing. SOLUTION: The storage battery discharge controller is provided with a storage battery selecting means; a charging/discharging means for accumulating power discharged at constant current in one battery selected by the storage battery selecting means, charging the accumulated power so as to return to the one storage battery, and supplying the accumulated power to a load connected to the group of storage batteries; a current bypass means for bypassing the currents flowing into the one storage battery from the other storage batteries, other than the one storage battery in the group of storage batteries so that the voltage of the one storage battery can be kept at substantially zero volt, when the voltage of the one storage battery is lowered to be a discharge limit voltage as the limit of discharge for the one storage battery; and an operation control means for controlling the operations of the charging/discharging means and the current bypass means.
