The lead-acid battery used in today''s automobile is made of plates, lead, and lead oxide in an electrolyte solution. This solution consists of 65% water and 35% sulfuric acid. This solution''s specific gravity or weight increases as the battery charges and decreases as the battery discharges.
Lead Acid. Lead acid uses sulfuric acid. When charging, the acid becomes denser as lead oxide (PbO 2) forms on the positive plate, and then turns to almost water when fully discharged. The specific gravity of the sulfuric acid is measured with a hydrometer. (See also BU-903: How to Measure State-of-charge). Lead acid batteries …
