How to Recondition Lead Acid Batteries

The Chemistry Behind Lead Acid Batteries. When a lead acid battery is charged, the sulfuric acid in the electrolyte reacts with the lead in the positive plates to form lead sulfate and hydrogen ions. At the same time, the lead in the negative plates reacts with the hydrogen ions in the electrolyte to form lead sulfate and electrons.
