BACKGROUND: A lead-acid cell is a basic component of a lead-acid storage battery (e.g., a car
When mixed ready for use in a lead–acid battery, the SG of the diluted sulphuric acid (battery acid) is 1.250 or 1.25 kg per liter. As the battery is charged or discharged, the proportion of acid in the electrolyte changes, so the SG also changes, according to the state of charge of the battery. Figure 5 SG test of an automobile battery
