✦ Synopsis

The potential of using electrochemical impedance spectroscopy (EIS) as a routine testing technique for the characterization of sealed lead/acid batteries was investigated with several generations of Gates 'J' type cells sampled from batteries with known histories. It was found that EIS measurements are sensitive to many fundamental cell characteristics such as cell design and standing time or shelf period but more importantly they were also very sensitive to temperature variations. For this reason and for the considerable effort required to standardize such a technique it is believed that EIS measurements are not a practical technique for a battery shop environment. In a controlled laboratory environment the same sensitivity to a multitude of parameters becomes very valuable for studying the internal mechanisms of these sealed systems.
