Principles of lead-acid battery. Lead-acid batteries use a lead dioxide (PbO 2) positive electrode, a lead (Pb) negative electrode, and dilute sulfuric acid (H 2SO 4) electrolyte (with a specific gravity of about 1.30 and a concentration of about 40%). When the battery discharges, the positive and negative electrodes turn into lead sulfate (PbSO

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.
Based on SOH, a battery is considered to be failed when the current capacity is less than 80% of the rated capacity. Therefore, the anomalies in lead acid battery can be detected by monitoring its parametric degradation.
The SOC for lead acid battery is determined from the parameters such as specific gravity (Aylor et al. 1992 ), open-circuit voltage (Mariani et al. 2013 ), cell temperature (Hunter and Anbuky 2003 ), cell voltage (Hariprakash et al. 2004) and Coulometric measurements (Ng et al. 2009 ).
VRLA battery has better thermal and electrical properties in comparison to other lead acid batteries (Hariprakash et al. 2008 ). VRLA battery is the most life limiting component of battery applications like UPS and therefore, their condition needs to be monitored at different operating conditions.
