WebMar 30, 2024 · Sulphuric acid is the aqueous electrolyte used in battery – lead acid batteries. Sulfuric or Sulphuric acid is diluted with chemically clean & pure water (de-mineralized water) to obtain about 37% concentration by weight of acid. The lead acid battery electrolyte concentration or battery acid ph differs from battery manufacturer to manufacturer. Web2.3.2.1 Lead–acid (LA) batteries. Lead–acid batteries contain metallic lead, lead dioxide, lead sulfate and sulfuric acid [1,2,3,6]. The negative electrodes are made of metallic lead containing also minor fractions of e.g., calcium, tin, antimony. The positive electrodes are made of lead oxides in various compositions.
