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.

Although batteries can vary depending on their chemistry, they have a few basic components: Cathode: The cathode is the positive electrode (or electrical conductor) where reduction occurs, which means that the cathode gains electrons during discharge.
Batteries are comprised of several components that allow batteries to store and transfer electricity. To charge and discharge batteries, charged particles (ions and electrons) must flow in particular directions and through particular components. Although batteries can vary depending on their chemistry, they have
Thus the nominal voltage is determined by the cell chemistry at any given point of time. The actual voltage produce will always be lower than the theoretical voltage due to polarisation and the resistance losses (IR drop) of the battery and is dependent upon the load current and the internal impedance of the cell.
Capacity: The entire energy in a battery is measured here, and it is usually expressed in ampere-hours (Ah). It provides information on how much charge the battery can deliver at a particular discharge rate. Energy Density and Power Density: The quantity of energy stored per unit of mass or volume is measured by the energy density (Wh/kg or Wh/L).
These criteria are essential for a number of reasons: Selection and Sizing: Engineers can select the best battery for a certain application by knowing the parameters and calculating the size and number of batteries required to match the specifications.
State Of Charge (SOC) The state of charge of a battery can often be determined from the condition of the electrolyte. In a lead–acid battery, for example, the specific gravity of the electrolyte indicates the state of charge of the battery. Other batteries may indicate the SOC by the terminal voltage. Depth of Discharge (DoD)
