Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide.
A lead acid battery contains plates of lead and lead dioxide submerged in an electrolyte solution made of sulfuric acid and water. When the battery discharges, the sulfuric acid reacts with the lead plates, creating lead sulfate and releasing electrons. These electrons flow through the circuit, providing the power your car needs.

A lead-acid battery is a rechargeable battery that relies on a combination of lead and sulfuric acid for its operation. This involves immersing lead components in sulfuric acid to facilitate a controlled chemical reaction. This chemical reaction is responsible for generating electricity within the battery, and it can be reversed to recharge the battery.

A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. The positive electrode consists of lead oxide. Both electrodes are immersed in a electrolytic solution of sulfuric acid and water.
With today’s higher expectations towards lead–acid batteries, red lead could increase the battery quality and become an alternative to installing additional curing and formation equipment. Conveyed either mechanically or pneumatically, the material handling of red lead is similar to that for leady oxide and is both simple and clean.
