Customer ServiceThe 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.
Within the lead-acid cells, the fine lead sponge is the active substance in the negative plates, while highly porous lead dioxide acts as the active substance in the positive plates. The plates are immersed in a sulfuric acid electrolyte solution that facilitates the discharge process.
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.
