Key Takeaways. Battery specific gravity is the ratio of the density of the battery electrolyte, relative to water with which it would combine if mixed evenly. The specific gravity of a battery should be between 1.265 and 1.299 for lead-acid batteries, indicating that the battery is fully charged and in good condition.
Make sure the battery is fully charged before adding more water to the cells. 4. Overwatering. Not only can your battery have too little water to function properly, but it can also have too much. Overwatering can cause the electrolytes to become diluted, which results in diminished battery performance levels.
However, it has been demonstrated that battery acid when the battery is fully charged has the maximum density at 800F or 26.670C as the temperatures drop below 800F, the battery will contract increasing the specific gravity of the acid.
