Battery sulfation is a common problem that can occur in lead-acid batteries, leading to degraded performance and a shortened lifespan. Sulfation happens when sulfuric acid in the battery''s electrolyte breaks down and forms crystals on the battery plates. These crystals, known as lead sulfate, can build up over time and reduce the battery''s capacity to hold a charge.

All rechargeable batteries degrade over time. Lead acid and sealed lead acid batteries are no exception. The question is, what exactly happens that causes lead acid batteries to die? This article assumes you have an understanding of the internal structure and make up of lead acid batteries.
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
Acid stratification has become a more popular reason for battery failure in recent times due to more electrical devices being added to cars and other road transport. It occurs when the acid in the electrolyte starts to concentrate in the lower half of the unit leading to a build up of sulfates on the bottom parts of the plates.
