The specific gravity of a lead-acid battery should be between 1.265 and 1.299 when fully charged, and anything below that indicates a low state of charge or other issues. The specific gravity of a battery''s electrolyte is affected by several factors, including temperature and the concentration of sulfuric acid.
How to Measure Specific Gravity of Battery
Pure sulfuric acid has a specific gravity of 1.835, since it weighs 1.835 times as much as pure water per unit volume. Since the electrolyte of a lead-acid battery consists of a mixture of water and sulfuric acid, the specific gravity of the electrolyte will fall between 1.000 and 1.835. Normally, the electrolyte for a battery is mixed such ...
How to Measure Specific Gravity of Battery
Lead-acid batteries use an electrolyte which contains sulfuric acid. Pure sulfuric acid has a specific gravity of 1.835, since it weighs 1.835 times as much as pure water per unit volume. Since the electrolyte of a lead-acid battery consists of a mixture of water and sulfuric acid, the specific gravity of the electrolyte will fall between 1.000 and 1.835.
Lead-acid battery, Battery care, Charging, Hydrometer.
A battery hydrometer is used to read the relative density (specific gravity) of the sulfuric acid in the electrolyte and check the charge of the battery. The density varies from about 1.28 in a fully charged battery to 1.15 in a discharged battery.
