Abstract : The external (surrounding) temperature variation majorly influences the battery lifetime and performance. The temperature variations lead to failure of individual cells as well as performance of the battery. Lead–acid 12 V/ 7.2 Ah battery is used for the analysis. For heating purpose, two heating coils are fitted inside the wooden chamber. Three thermocouples are connected with DAQ card to measure the temperature. For every 10 full cycle periods, the temperature is increased by 10 °C up to 60 °C. At this stage, the battery starts to explode due to high chemical reactions, fast discharging, and charging cycles. The anode and cathode plates were removed from the battery and analyzed with the help of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). From the DSC results, the change of the heat capacity of the anode and cathode plates is observed. Likewise, TGA result shows the degradation of both anode and cathode plates.
