What is the specific gravity of a fully charged lead-acid cell at 80 degrees?

The specific gravity of a fully charged lead-acid battery cell is a critical measurement that indicates the state of charge and the electrolyte concentration within the battery. At 80 degrees Fahrenheit, the specific gravity of a fully charged lead-acid cell typically ranges between 1.265 and 1.300.

Choosing 1.28 aligns perfectly with this range, making it a suitable representation of the specific gravity at that temperature. This value indicates that the electrolyte is adequately concentrated, providing optimal performance for the battery. Understanding the specific gravity is crucial because it helps in assessing the health and charge status of the lead-acid battery, which is vital for ensuring effective energy production and storage in power systems.

If a student is studying the characteristics of lead-acid batteries, recognizing the standard specific gravity readings at different temperatures can significantly aid in troubleshooting and maintaining battery health.
