And when the electric power changes into chemical energy then it is known as discharging of the battery. During the charging process, the current passes inside the battery because of chemical changes. The lead-acid battery mainly uses two types of charging methods namely the constant voltage charging and constant current charging.
A more precise method is to apply a fully saturated charge and then compare the specific gravity readings (SG) on the individual cells of a flooded lead acid battery with a hydrometer. An equalization is to be performed if the SG difference between the cells is 0.030.
