A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The components in Lead-Acid battery includes; stacked cells, immersed in a dilute solution of sulfuric acid (H 2 SO 4), as an electrolyte, as the positive electrode in each cells comprises of lead dioxide (PbO2), and the negative electrode is made up of a sponge lead.
A plug is inserted which is linked to the lead-acid battery and the chemical reaction proceeds in the opposite direction. In cases where the sulphuric acid in the battery (or some other component of the battery) has undergone decomposition, the charging process may become inefficient. Therefore, it is advisable to check the battery periodically.
The reaction principle of lead-acid battery remains unchanged for over 150 years from the invention. As shown in reaction formula for the discharging of battery, at the negative electrode, metallic lead reacts with the sulfate ions in water solution to produce lead sulfate and release electrons (Formula 1).
The usable life of a lead acid battery is typically approximately 5 years or 250–1000 charge-discharge cycles, depending on the depth of discharge . P. Kurzweil, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2023 The lead-acid battery is the most important low-cost car battery.
Sulfation prevention remains the best course of action, by periodically fully charging the lead–acid batteries. A typical lead–acid battery contains a mixture with varying concentrations of water and acid.

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. Desulfation is the process of reversing sulfation …
