A reliable diagnostics of lead-acid batteries would become mandatory with the induction of an improved power net and the increase of electrically assisted features in future automobiles. Sparse-impedance spectroscopic technique described in this paper estimates the internal resistance of sealed automotive lead-acid batteries in the frequency range 10 Hz–10 kHz, usually produced by the alternators fitted in the automobiles. The state-of-health of the battery could be monitored from its internal resistance.
