AI Customer ServiceIf 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.
If you want to increase the specific gravity of a lead-acid battery, you have to increase the acid concentration within its electrolyte. You can do this by adding battery acid into the battery or, if possible, reduce the volume of water within the power cell. That will lessen the acidity of the electrolyte, which reduces the specific gravity of it.
The specific gravity decreases during the discharging of a battery to a value near that of pure water and it increases during a recharge. The battery is considered fully charged when specific gravity reaches it's highest possible value. Specific gravity does, of course, vary with temperature and the quantity of electrolyte in a cell.
In case the battery’s specific gravity gets too high, which can also be dangerous for the battery, you will need to decrease it by adding water into it. It will neutralize the acid in it, decreasing the electrolyte acidity, which also reduces the specific gravity of the battery. Just to be clear and to leave a conclusive answer.
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. Another factor that can lead to low specific gravity is a decrease in acid concentration.
In lead-acid batteries, this is a mixture of distilled water (pure H₂O) and sulfuric acid (H₂SO₄). Sulfuric acid can be dangerous because it is odorless, colorless and strongly acidic so take precautions when working around batteries, especially if the electrolyte is leaking.
