✦ Synopsis

The ohmic resistance of maintenance-free lead-acid batteries has been identified as an ideal parameter for the prediction of the state-of-charge using the a.c. impedance technique. The ohmic resistance has been found to mirror the change in specific gravity of the battery electrolyte when charged or discharged.
