What may happen to a lead battery when overcharged?

acid leak
polarization switch
explosion
sulfurization
Any lead­-acid battery system when over­charged will produce hydrogen gas by elec­trol­y­sis of water. If the rate of over­charge is small, the vents of each cell allow the dis­si­pa­tion of the gas. A severe over­charge may produce a flammable con­cen­tra­tion of hy­dro­gen.
