Lead-acid Battery Handbook
Principles of lead-acid battery. Lead-acid batteries use a lead dioxide (PbO 2) positive electrode, a lead (Pb) negative electrode, and dilute sulfuric acid (H 2SO 4) electrolyte (with a specific gravity of about 1.30 and a concentration of about 40%). When the battery discharges, the positive and negative electrodes turn into lead sulfate (PbSO
