Acid burns to the face and eyes comprise about 50% of injuries related to the use of lead acid batteries. The remaining injuries were mostly due to lifting or dropping batteries as they are quite heavy. Lead acid batteries are usually filled with an electrolyte solution containing sulphuric acid.
Sulfuric acid facilitates the charging mechanism in lead-acid batteries by acting as the electrolyte. When the battery discharges, sulfuric acid reacts with lead dioxide (PbO2) and spongy lead (Pb) to produce lead sulfate (PbSO4) and water. During charging, an external electrical current reverses this reaction.
