In the context of lead-acid batteries, specific gravity is a measure of the electrolyte’s density compared to water.

As a battery discharges, the specific gravity decreases, and as it charges, the specific gravity increases.
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.
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.
The specific gravity of the electrolyte of a fully charged lead-acid cell is about 1.28; This can be measured by means of a hydrometer In practice, the state of charge of a lead-acid cell (or battery) is determined from the specific gravity of the electrolyte.

The specific gravity of the electrolyte is directly proportional to the amount of acid in the electrolyte. The more acid in the electrolyte, the higher the specific gravity. Conversely, the less acid in the electrolyte, the lower the specific gravity. The specific gravity of a battery is also affected by the battery’s state of charge.
