Battery sulfation

Battery sulfation refers to the buildup of lead sulfate crystals on the plates of lead-acid batteries. This phenomenon occurs when a battery is left discharged for an extended period or is consistently undercharged, leading to reduced capacity and overall performance. Sulfation can cause the battery to hold less charge, shorten its lifespan, and, in severe cases, render it unusable. Understanding battery sulfation is important for proper battery maintenance, helping to prevent damage and extend the life of automotive, solar, and backup power batteries.
