Battery Specifications Explained
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

INTERNAL OHMIC MEASUREMENTS AND THEIR …
This natural degradation causes an increase in the resistance of a cell''s internal conduction path. Valve-regulated lead acid (VRLA) batteries have other internal effects that also can cause loss of capacity and an associated increase in resistance. Internal ohmic measurements are intended to measure this change in resistance. A measured ...
