PROBLEM TO BE SOLVED: To provide a power supply and a charging method, whereby a lead acid battery can be simply regenerated, and its life can be substantially extended. SOLUTION: In this power supply for recharging, one end of a rectifier is connected to one of secondary terminals of a sliding transformer, and the other end of the rectifier is connected to one of terminals connected to the lead acid battery. In this recharging method, a commercial ac voltage is transformed by using the sliding transformer, the transformed ac is rectified by the rectifier, the rectified current is sent to the lead acid battery wherein a single or a plurality of lead acid batteries are connected in series, and the lead acid battery is charged by a low current value.
