Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
In a lead-acid battery, two types of lead are acted upon electro-chemically by an electrolytic solution of diluted sulfuric acid (H 2 SO 4). The positive plate consists of lead peroxide (PbO 2), and the negative plate is sponge lead (Pb), shown in Figure 4. Figure 4 : Chemical Action During Discharge
Charging is crucial as it aims to maximize lead-acid batteries’ performance and life. Overcharging results in higher battery temperature, higher gassing rates, higher electrolyte maintenance, and corrosion of components, while repeated undercharging leads to a gradual reduction of battery capacity, which is sometimes irreversible.
Charging a lead acid battery at high temperatures can cause serious damage to the battery and even lead to explosions. When a battery is overcharged, it may experience: Reduced Battery Life: Exaggerated use increases internal resistance, reducing the number of cycles performed.
A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
Lead-acid batteries may be charged with the CCCV charge method which is a multi-step charging procedure assuring the battery is fully charged without overcharging and degrading it. This method involves the following three stages: Constant-Current Charge, topping charge, and float charge.

Discharge and Charging of Lead-Acid Battery
As a lead-acid battery charge nears completion, hydrogen (H 2) gas is liberated at the negative plate, and oxygen (O 2) gas is liberated at the positive plate. This action occurs since the charging current is usually greater than the current necessary to reduce the remaining amount of lead sulfate on the plates. The excess current ionizes the ...
