Discharging a lead-acid battery is a spontaneous redox reaction. When a single lead-acid galvanic cell is discharging, it produces about 2 volts. 6 lead-acid galvanic cells in series produce 12 volts.

When a battery dies, it is because one or more of the chemical reactants is more or less used up. In a car battery (sometimes called a lead-acid battery) the cathode is lead dioxide (PbO2), the anode is a sponge of lead (Pb), and the solution is sulfuric acid (H2SO4)
