Acid stratification happens naturally in lead-acid batteries. The fluid in a battery is called electrolyte. The electrolyte is a mixture of sulphuric acid and water. Acid is heavier than water and is fundamental to a lead-acid battery's electrochemical charge and discharge process.
Acid is heavier than water and is fundamental to a lead-acid battery's electrochemical charge and discharge process. Acid stratification happens when the heavier acid in the battery’s electrolyte separates from the water and assembles at the bottom of the battery’s cell, creating an area of very high specific gravity electrolyte.
Since electrical current moves more easily through water (top part of the cell) than it does through acid (bottom part of the cell), stratified acid concentrates charging current and charging heat at the upper part of the plate, accelerating corrosion which dramatically lowers the battery’s cranking power (“CCA”).
