Hi: Once again, there is no such thing as a battery failure from the so called "sulfation", except (the pathological condition) if large lead sulfate crystals are formed from the battery sitting in an inactive condition for months or from frequently undercharging. One again, those familiar with a bit of chemistry know that there is no such thing as "sulfur" crystals in the battery plates. The lead-acid battery operates by the following basic chemical reactions:
Discharge: Lead dioxide (pos) and spongy lead (neg) react with sulfuric acid to form lead sulfate. The battery could not work without this reaction. Charge: The backward to discharge chemical reaction . Lead Sulfate reacts with water to form sulfuric acid, lead dioxide and spongy lead. Sulfation during discharge is absolutely necessary for the lead acid battery to operate.
