Lead-acid Battery Manufacture: Sulfuric Acid

Sulfuric acid concentration control in lead-acid battery manufacturing

Lead-acid and gel batteries are commonly used for automobiles and electric vehicles that need long durability.

In lead-acid battery manufacturing, sulfuric acid (H₂SO₄) is used to activate the lead elements of the lead battery to get the power effect. For this process, the acid with correct concentration level is required. The acid is prepared by mixing the fresh acid with water and pumping it into the lead activation plant.

The Vaisala Polaris™ process refractometer measures in-line the sulfuric acid concentration necessary to ensure the successful power activation effect of the lead-acid battery.
