As you know, lead acid battery electrolyte is a mixture of water and sulfuric acid. Sulfuric acid is heavier than water. So, when the battery is not in use, the acid tends to settle down at the bottom of the cell. Stratification also occurs if the battery charge is regularly around 80-85%, not fully charged. This can happen if you use your car for driving short distances.
