Water (H 2 O) is consumed and H 2 SO 4 is formed in above chemical reactions. This increases the specific gravity of the electrolyte. Ultimately, the cell regains its previous (before discharging) chemical compositions. The anode is transformed into lead peroxide (PbO 2) and cathode into the spongy lead (Pb).
In the case of a lead-acid battery, the chemical reaction involves the conversion of lead and lead dioxide electrodes into lead sulfate and water. The sulfuric acid electrolyte in the battery provides the medium for the transfer of electrons between the electrodes, resulting in the generation of electrical energy.
When a lead-acid battery is in use, it undergoes a discharge process. During this process, the lead-acid battery releases electrical energy as its chemical energy is converted. The discharge process can be described as follows: The sulfuric acid in the electrolyte combines with the lead dioxide on the positive plate to form lead sulfate and water.
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.
The anode is transformed into lead peroxide (PbO 2) and cathode into the spongy lead (Pb). Water is consumed and sulphuric acid is formed which increases the specific gravity of electrolyte from 1.18 to 1.28. The terminal voltage of each battery cell increases to 2.2 to 2.5V.
It is usually made of lead or copper. When a lead-acid battery is charged, a chemical reaction occurs that converts lead oxide and lead into lead sulfate and water. This reaction occurs at the positive electrode, which is made of lead dioxide. At the same time, hydrogen gas is produced at the negative electrode, which is made of lead.
The battery consists of two lead plates, one coated with lead dioxide and the other with pure lead, immersed in an electrolyte solution of sulfuric acid and water. When the battery is charged, a chemical reaction occurs that converts the lead dioxide into lead sulfate and the pure lead into lead sulfate as well.

Lead-Acid Battery Specific Gravity. When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged. The density of electrolyte related to the density of water is termed its specific gravity.
