Specific Gravity of Battery Electrolyte Review One of the key parameters of battery operation is the specific gravity of the electrolyte. Specific gravity is the ratio of the weight of a solution to the weight of an equal volume of water at a specified temperature.
Specific gravity is used as an indicator of the state of charge of a cell or battery. However, specific gravity measurements cannot determine a battery's capacity. During discharge, the specific gravity decreases linearly with the ampere-hours discharged as indicated in the illustration below.
Specific gravity is the ratio of the weight of a solution (sulfuric acid in this case) to the weight of an equal volume of water at a specified temperature. This measurement is usually measured using a Hydrometer. The specific gravity of a fully charged GB Industrial Battery is the industry standard of 1.285.
Specific gravity is the ratio of the weight of a solution to the weight of an equal volume of water at a specified temperature. Specific gravity is used as an indicator of the state of charge of a cell or battery. However, specific gravity measurements cannot determine a battery's capacity.
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 that the specific gravity is less than 1.350. Specific gravity is measured with a hydrometer.
