Introduction

Lead acid batteries have been a cornerstone of energy storage solutions since their invention in 1859 by Gaston Planté. They are widely used in automobiles, emergency lighting, and various types of backup power systems. Understanding the components and chemistry of these batteries is crucial for optimizing their performance and lifespan.

Acid Used in Lead Acid Batteries

Lead acid batteries utilize sulfuric acid (H₂SO₄) as their electrolyte. Sulfuric acid acts as a medium to facilitate the flow of electric current between the lead dioxide (PbO₂) positive plate and the lead (Pb) negative plate. The concentration and purity of sulfuric acid are critical to the efficiency and lifespan of the battery.

Chemistry Behind Lead Acid Batteries

The chemical reaction in a lead acid battery during discharge can be represented by the following equations:

• PbO₂ + 4H⁺ + SO₄^2- + 2e^- → PbSO₄ + 2H₂O (at the positive plate)
• Pb + SO₄^2- → PbSO₄ + 2e^- (at the negative plate)

During charging, the above reactions are reversed. The specific gravity of the sulfuric acid varies typically between 1.200 and 1.300 in a fully charged battery, indicating its state of charge.
