The term “battery acid” refers to the electrolyte used in batteries. For lead acid batteries this is sulfuric acid (H 2 SO 4). Sulfuric acid is colorless, odorless, and strongly acidic. Why measure the density / specific gravity of battery acid? Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge.
In lead-acid batteries, this is a mixture of distilled water (pure H₂O) and sulfuric acid (H₂SO₄). Sulfuric acid can be dangerous because it is odorless, colorless and strongly acidic so take precautions when working around batteries, especially if the electrolyte is leaking. What is Specific Gravity?
Flooded lead acid batteries contain a liquid acid solution that is critical to the battery's performance. The acid concentration is determined with a tool called a hydrometer; the hydrometer measures density, or specific gravity. Specific gravity (SG) is very important because it's the most direct indicator of battery state of charge.
Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge. Due to chemical reactions during discharge, the density of the sulfuric acid electrolyte (or its specific gravity) decreases.
