FAQs about What is the specific gravity formula of lead-acid batteries
What is battery acid / specific gravity?
The term “battery acid” refers to the electrolyte used in batteries. For lead acid batteries this is sulfuric acid (H 2 SO 4). Sulfuric acid is colorless, odorless, and strongly acidic. Why measure the density / specific gravity of battery acid? Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge.
What is specific gravity in a lead-acid battery?
In the context of lead-acid batteries, specific gravity is a measure of the electrolyte's density compared to water. In practical terms, the specific gravity of a battery's electrolyte provides insights into its state of charge. As a battery discharges, the specific gravity decreases, and as it charges, the specific gravity increases.
What is the specific gravity of a battery electrolyte?
The solution is around 35% sulfuric acid and 65% water. Concentrated sulfuric acid has a specific gravity of 1.84 while the specific gravity of distilled water is 1.00. When the sulfuric acid is diluted with water to make the battery electrolyte, the specific gravity of the end product should be between 1.26 and 1.30.
How often should battery acid specific gravity be measured?
Measurement of battery acid specific gravity is important to ensure that the battery is in the right condition to enhance operational efficiency. As a battery maintenance routine, always measure the specific gravity at least once a month.
How do you increase the specific gravity of battery acid?
When the specific gravity in battery acid has been low due to spillage or excess watering, one may decide to raise the gravity to the desired levels. You may achieve this by adding sulfuric acid to distilled water to achieve the desired levels. Note: Never add water to acid as this may cause explosive reaction.
What should the specific gravity of a battery be?
The specific gravity of a battery should be between 1.265 and 1.299 for lead-acid batteries. This range indicates that the battery is fully charged and in good condition. If the specific gravity is below 1.225, the battery is discharged and needs to be charged. If the specific gravity is above 1.299, the battery is overcharged and may be damaged.

A battery acid specific gravity is defined as “the ratio of the density of the battery acid, relative to water with which it would combine if mixed evenly” A standard solution is defined as “a solution that contains some number of grams of solute per liter of solvent.” The battery acid is made up of sulfuric acid that is diluted with water.
What determines the specific gravity of a battery cell?
The specific gravity of a battery is determined by the concentration of sulfuric acid in the electrolyte. Therefore, the specific gravity of a battery cell will be higher if it contains more electrolyte. Different types of batteries have different specific gravities.
What is the specific gravity of a GB industrial battery?
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.
How do you increase the specific gravity of battery acid?

You may achieve this by adding sulfuric acid to distilled water to achieve the desired levels. Note: Never add water to acid as this may cause explosive reaction.
What is the specific gravity of a lead-acid battery?
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.
