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.

Red lead: understanding red lead in lead−acid batteries
Red lead is sometimes confused with the tetragonal form of leady oxide (α-PbO), which also has a red color, but actually is the raw material for the production of red lead. Red lead forms through an oxidation process when α-PbO is heated to around 450–500 C, but decomposes to yellow litharge (β-PbO, orthorombic) when temperatures …
