However, compared with research on lithium battery detection, there are relatively few researches using EIS to judge the life of lead-acid batteries [16, 17].Currently, no reliable method exists for estimating SOH based on a single impedance or EIS because a single measurement frequency of impedance information does not provide enough data to accurately

Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
The use of IRT for automatic fault diagnosis of lead acid battery offers the advantage of detecting the early failures in a fast, non-contact and non-invasive manner. Therefore, the present work is focused on determination of the qualitative nature of fault in VRLA battery used in UPS from IRT and Fuzzy logic techniques.
At high temperatures, chemical reaction occurs faster in the cells which cause the rise in the internal resistance and joule heating of lead acid battery. With the lapse of time, degradation failure of battery occurs due to the reduction in its capacity and efficiency.
