Summary:PROBLEM TO BE SOLVED: To suppress insufficient charge and sulfation of a lead-acid battery while being left for a long period of time. SOLUTION: The apparatus of suppressing deterioration of a lead-acid battery comprises a discharge means for discharging a lead-acid battery, an electricity storage device for storing electrical charge in discharging, a charging means for charging the lead-acid battery with the electrical charge stored in the electricity storage device, and a control means for controlling so that charging and discharging are repeatedly performed. Repeating charge and discharge remarkably suppresses sulfation of the lead-acid battery active material and the capacitive deterioration, as compared with the case where charging alone or discharging alone is performed.
