What Is Battery Acid? Sulfuric Acid Facts
The net reaction when a lead-acid battery discharges is: PbO 2 (s) + Pb(s) + 2H 2 SO 4 (aq) → 2PbSO 4 (s) + 2H 2 O(l) Charging and Discharging. When the battery is charging, these reactions reverse, where lead oxide forms lead, lead dioxide, and sulfuric acid. An applied electrical current drives the chemical reactions.
