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.
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. Figure 1 : Simple Hydrometer
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.
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. Figure 1 : Simple Hydrometer A simple hydrometer consists of a glass float inside a glass tube, as shown in Figure 1. The hydrometer float is weighted at one end and sealed at both ends.
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.
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.
