Battery acid is dilute sulphuric acid (H₂SO₄). In every lead-acid battery, concentrated sulphuric acid is diluted with demineralised water to typically 27–39% by weight — a specific gravity between 1.200 and 1.300 depending on the battery type. It is a strong acid: at these strengths the pH sits below 1. And it is not merely … Read more

VRLA battery full form: Valve Regulated Lead Acid battery. A VRLA battery is a lead-acid battery in which the electrolyte is immobilised and the container is sealed with one-way pressure-relief valves. Gases produced on charge are retained and recombined inside the cell, so the battery never needs water addition over its service life. The two … Read more
