naturally occurs during normal charging, but when a lead acid battery is overcharged, the electrolyte solution can overheat, causing hydrogen and oxygen gasses to form, increasing pressure inside the battery. Unsealed flooded lead acid batteries use venting technology to relieve the pressure and recirculate gas to the battery.
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.
