Over-discharging a lead-acid cell, like over-charging, can severely shorten the service life of the cell. The circuit moni-tors the discharging of the battery and disconnects all load from the battery when its voltage reaches a specified cutoff point.
Abstract. The traditional methods of charging lead-acid batteries depend on stabilizing the current or voltage through simple electronic circuits, which causes the shorten the life of the batteries due to damage to the electrodes or the hot and dry batteries.
