The electrolyte solution in a lead-acid battery expands when warm and contracts when cold. This affects the density and specific gravity of the electrolyte. Hydrometers measure the specific gravity of the electrolyte to determine the state of charge. And changes in temperature can alter our results.
If the specific gravity of your lead-acid battery is low, it means that the battery is not fully charged. To correct this, you should recharge the battery using an appropriate charger. If the low specific gravity is due to a lack of electrolyte, you can add distilled water to the battery to bring the electrolyte level up to the recommended level.
Abattery hydrometer is the best way to check the specific gravity of a lead acid battery. This device measures the density of the sulfuric acid in the electrolyte and allows you to see how charged the battery is. Generally, the density of the acid will range from 1.28 in a fully charged battery to 1.15 in a discharged battery.
Specific gravity is a crucial aspect of battery health, as it indicates the state of charge and the overall condition of the battery. Specific gravity readings are taken to determine the concentration of sulfuric acid in the battery’s electrolyte.
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.
There are several factors that can lead to a decrease in the specific gravity of a battery. One common cause is sulfation, which occurs when lead sulfate crystals build up on the battery plates. This can reduce the surface area of the plates, making it harder for the battery to hold a charge.
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.

Generally, the acid level should be between 25% and 30% for lead-acid batteries. This ensures proper electrolyte balance and helps prevent sulfation, which can hinder battery performance. It is important to regularly check and replenish the acid levels if necessary, using distilled water. By paying attention to the acid levels, you can extend the lifespan of your …
Now, let''s interpret our reading. Note the number on the scale where the electrolyte meets the float. This number represents the specific gravity of the electrolyte in the battery. A higher specific gravity indicates a higher charge state. A fully charged battery should have a specific gravity between 1.265 and 1.299.
In flooded lead–acid batteries, roughly 85% of all failures are related to grid corrosion, while in valve-regulated lead–acid batteries, grid corrosion is the cause of failure in about 60% of cases. This is a problem that develops over time and it typically affects batteries that are close to end of life. In other words, if the preventable causes of failure are eliminated, then …
