Car Battery Reconditioning (A How-To for LFA Batteries)

The lead acid battery generates electrical energy through a chemical reaction between its electrolyte fluid (consisting of sulfuric acid and water) and lead plates. Each time a battery discharges, lead sulfate crystals form on the battery plates. When the lead acid battery is recharged, the lead sulfate disperses. However, not all of it goes away.

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.
