What is Battery Sulfation & How to Reverse It
As part of the reactions to generate electricity, the sulfuric acid splits into sulfate and hydrogen atoms. Sulfate is attracted to lead, and it bonds to either the anode or cathode to form lead sulfate. When the battery is recharged, the process reverses, meaning the sulfate splits from the lead and returns to the electrolyte solution.
