It is quite clear that these quantities are not the same from one another. Despite this, they are often used interchangeably and it is key to clearly distinguish between them. Density is a measure of mass per unit volume. While on the other hand, specific gravity is a measure of the relative density of a fluid with respect to.

Maintenance-free batteries, also known as sealed batteries or valve-regulated lead-acid (VRLA) batteries, have a different acid concentration compared to conventional batteries. These batteries are designed to be maintenance-free, eliminating the need to add water or check the acid concentration regularly. The acid concentration in maintenance-free batteries
The specific gravity of battery acid is primarily influenced by the concentration of sulfuric acid. A fully charged battery will have a higher specific gravity due to the higher concentration of acid, while a discharged battery will have a lower specific gravity due to the lower acid concentration.
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.

2. Specific Gravity: Specific gravity is a measure of the density of a liquid compared to the density of water. In lead acid batteries, the specific gravity of sulfuric acid provides an indication of the battery''s state of charge. A fully charged battery will have a higher specific gravity than a discharged battery. 3. Electrolyte Level: It
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 concentration levels of sulfuric acid in the electrolyte changes as the battery undergoes the cycles of charge and discharge. As the battery discharges, the sulfur ions in the sulfuric acid solution react with lead to form lead sulfides and water. As the water levels in the electrolyte increases, the specific gravity of the acid drops.
Sulfuric acid has a specific gravity of about 1.835. Water has a specific gravity of 1.000 and a charged lead–acid battery has a specific gravity of about 1.280. One would expect the sulfuric acid to flow downward after it is generated at the plates and collect at the bottom of the battery. This effect is well known , .
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.
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. When the specific gravity varies too much from these figures, it means the electrolyte does not present a conducive environment for chemical reactions to take place.
Measuring specific gravity of battery water (sulphuric acid) and the correction for temperature: The gravity of the acid used in battery is read by the hydrometer and the temperature is read by a mercury-in-glass type thermometer. Avoid parallax error by keeping the lead acid battery electrolyte level in the hydrometer in the same level of the eye.
