Experimental study of Optimum Working Temperature Range of Deep Cycled Lead Acid Solar Battery

Abstract

The optimum working temperature range of deep cycled lead acid solar battery was studied. A 4- different model of deep cycled
Lead acid battery of 12V, 100amp-hr was used along 250 Watts mono crystalline silicon solar panel. A digital multimeter, charge
controller, 250 Watts incandescent bulb (load), inverter and a digital thermometer were employed in the study. The experimental
set-up was done in the environ of University of Port-Harcourt (Latitude 40 55’58’’N and Longitude 60 59’55’’East), Rivers State,
Nigeria (tropical climate region). The measured voltage and temperature during charging and discharging processes consequently determine the charging and discharging efficiency of the battery. Through this, the optimum working temperature range of the considered Lead Acid battery falls within 29OC and 37OC.
