What Should You Do If Specific Gravity Of Battery Is Low?

When it comes to automotive lead-acid batteries, one way of checking the amount of charge left is by measuring the specific gravity. It is defined as the ratio of the battery''s electrolyte weight against the weight of water with exact volume. The higher the acid concentration within the cell, the higher the specific gravity it

How to Repair a Faulty or Weak Cell in a 12-volt Battery

A fully charged battery has a specific gravity of 1.265 and no cell should differ by more than 0.05. Add acid to any cell below the minimum specific gravity, following the manufacturer''s instructions. Recharge the battery and test it again. If a cell is still faulty, it probably has been damaged by sulfation.
