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.
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.
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. A fully charged battery will have a higher specific gravity than a discharged battery. As the battery discharges, the specific gravity of the electrolyte decreases.
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.
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.
1. Hydrometer: A hydrometer is a tool specifically designed to measure the specific gravity of liquids. It consists of a glass tube with a weighted float and a scale. To measure battery acid specific gravity, extract some acid from the battery using a hydrometer and immerse the float into the acid.
