Specific Gravity Battery Testing

Specific Gravity Battery Testing

The specific gravity also increases as the battery is recharged. A hydrometer is used to measure the specific gravity of the electrolyte solution in each cell. It's a tool used to measure the density or weight of a liquid compared to the density of an equal amount of water.
In the case of battery testing, the hydrometer is measuring the specific gravity of the battery's electrolyte. The higher the acid concentration in the electrolyte, the higher the specific gravity. Based on the specific gravity, the user can determine the state of charge of the battery.
Storage Battery Systems offers both manual hydrometers and digital hydrometers for the measurement of batteries' specific gravity.
Every time I check the Specific Gravity, it's in the red, 1.175 or lower. Took the new batteries back to store, all 900 lbs. They said they were good and the SG was .
How to use a hydrometer to measure the specific gravity of the battery's electrolyte.. Wait a while before testing so that the new water has time to mix with the .
