What causes sulfation in lead-acid batteries?

Sulfation is a major cause of decreased battery capacity in lead-acid batteries. When lead sulfate crystals build up on the battery plates, they create a barrier that prevents the battery from holding a charge. This buildup reduces the active surface area of the electrodes, which in turn reduces the amount of energy the battery can store. As a result, the battery''s …

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. Desulfation is the process of reversing sulfation …
