How Does Lead-Acid Batteries Work?
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
Understanding Acid Stratification in Lead Acid Batteries
Causes of Acid Stratification. 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 ...
