# Battery Specific Gravity Chart

As a battery user, it is essential to understand how your battery works and how its health can be measured. 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 batteryâ€™s state of charge and health.

Battery Specific Gravity Chart
Specific Gravity (sg) State Of Charge (%) Remaining Capacity (%)
1.265 100 100
1.225 80 80
1.190 60 60
1.155 40 40
1.120 20 20
1.080 0 0

## What Should the Specific Gravity of a Battery Be?

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.

## What is a Good Battery Hydrometer Reading?

A good battery hydrometer reading is between 1.265 and 1.299. This reading indicates that the battery is fully charged and in good condition. If the reading is below 1.225, the battery is discharged and needs to be charged. If the reading is above 1.299, the battery is overcharged and may be damaged.

## What is the Specific Gravity of a Fully Charged 12v Battery?

The specific gravity of a fully charged 12v battery is between 1.265 and 1.299. 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.

## What is Specific Gravity in 24 Volt Battery?

The specific gravity in a 24 volt battery should be the same as in a 12 volt battery. The specific gravity range of a fully charged 24 volt battery is between 1.265 and 1.299. 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.

## Conclusion

Understanding your batteryâ€™s specific gravity is crucial to maintaining its health and prolonging its lifespan. By using a battery hydrometer and interpreting the readings using a battery specific gravity chart, you can determine the state of charge and health of your battery. Always remember to follow safety precautions when working with batteries and consult with a professional if you have any questions or concerns.
