When Should You Add Water to a Battery?

The optimal time to add water to a lead-acid battery is during its charging cycle. When a lead-acid battery is charged, the electrolyte solution (a mixture of water and sulfuric acid) breaks down into hydrogen and oxygen gas, which escape through the vent caps. This process is called gassing, and it causes the electrolyte level to drop.

What Is Battery Acid? Sulfuric Acid Facts

Battery acid is a common name for sulfuric acid (US) or sulphuric acid (UK). Sulfuric acid is a mineral acid with the chemical formula H 2 SO 4. In lead-acid batteries, the concentration of sulfuric acid in water ranges from 29% to 32% or between 4.2 mol/L and 5.0 mol/L. Battery acid is highly corrosive and able to cause severe burns.
