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.
