Abstract
Electrochemical batteries are being used in various applications including UPS back-up systems, grid stability, off grid power supply. The life of battery depends on selected chemistry, charge/discharge cycles, rates (C-rate), depth of discharge (DOD) and operating temperature [1]. In this paper, the life expectancy of valve regulated lead acid (VRLA) battery used for off grid power supply application is studied operating at different temperature environment. The result shows operating VRLA batteries at 25°C with required additional cooling demand has minor impact on battery charge and discharge cycles with significant improvement of the life cycle compared to operating the battery at 32 °C
