A common cause of battery failure is acid stratification. The electrolyte on a stratified battery concentrates on the bottom, causing the upper half of the cell to be acid poor. … High acid concentration on the bottom, on the other hand, artificially raises the open circuit voltage.
How do you check for a dead cell in a car battery?
Once a cell goes dead, the battery is bad and must be replaced. The best method to test a car battery for a dead cell is to check the specific gravity of the electrolyte fluid. Specific gravity is the density of the electrolyte fluid compared to water. The specific gravity for the electrolyte is ideally 1.265.
