Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
The Charging begins when the Charger is connected at the positive and negative terminal. the lead-acid battery converts the lead sulfate (PbSO 4) at the negative electrode to lead (Pb) and At the positive terminal, the reaction converts the lead sulfate (PbSO 4) to lead oxide. The chemical reactions revers from discharging process
The Discharge of the lead-acid battery causes the formation of lead sulfate (PbSO 4) crystals at both the positive electrode (cathode) and the negative electrode (anode), and release electrons due to the change in valence charge of the lead. This formation of lead sulfate uses sulfate from sulfuric acid which is an electrolyte in the battery.
