by Editorial Staff. Specific gravity is defined as the ratio comparing the weight of any liquid to the weight of an equal volume of water. The specific gravity of pure water is 1.000. Lead-acid batteries use an electrolyte which contains sulfuric acid.
• Specific Energy (Wh/kg) – The nominal battery energy per unit mass, sometimes referred to as the gravimetric energy density. Specific energy is a characteristic of the battery chemistry and packaging. Along with the energy consumption of the vehicle, it determines the battery weight required to achieve a given electric range.
One way to determine the health of your battery is to use a battery hydrometer and check its specific gravity. A battery specific gravity chart can help you interpret the readings and determine the battery’s state of charge and health.
22 Οκτ 2021 · 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.
The specific gravity for a given battery is determined by the application it will be used in, taking into account operating temperature and battery life. Typical specific gravities for certain applications are shown in Table 1.
Specific Gravity (SG) When acid is mixed with water, the specific gravity of the resulting electrolyte will be between that of water, which is 1 kg per liter or an SG of 1.000, and that of sulphuric acid which, at 100 per cent pure, has an SG of 1.84 or 1.84 kg per liter.
