Understanding Cell and Battery Construction
Although a lead–acid battery could be thought of as having pure lead plates, the lead metal actually contains about 10% antimony to increase the strength of the lead plate. Separator Electrodes that are kept close together will occasionally touch, causing short circuits and resulting in high fault currents.
