The working principle of a lead-acid battery is based on the chemical reaction between lead and sulfuric acid. During the discharge process, the lead and lead oxide plates in the battery react with the sulfuric acid electrolyte to produce lead sulfate and water. The chemical reaction can be represented as follows:
Definition: The lead acid battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost.
The chemistry of lead-acid batteries involves oxidation and reduction reactions. During discharge, lead dioxide and sponge lead react with sulfuric acid to produce lead sulfate (PbSO4) and water. When recharged, the process is reversed, regenerating lead dioxide, sponge lead, and sulfuric acid.
Terminals: Connect the battery to the external circuit. Figure 1: Lead Acid Battery. The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state.
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. As a by-product of this reaction, hydrogen is evolved.
To ensure optimum performance, regularly clean any lead oxide buildup on the terminals. The construction of lead acid batteries involves several key components. Each battery contains two lead plates, one made of lead dioxide and the other of sponge lead, submerged in sulfuric acid electrolyte.

Before directly jumping to know the concepts related to lead acid battery, let us start with its history. So, a French scientist named Nicolas Gautherot in the year 1801 observed that in the electrolysis testing, there exists a minimal amount of current even when there is a disconnection of the main battery.
The operational rhythm of a lead-acid battery resonates with the cyclic symphony of charging and discharging. During charging, an external electrical current impels the reversal of chemical reactions, coaxing lead dioxide to revert to lead sulfate at the positive electrode and lead to transform into lead sulfate at the negative electrode.
