The heat disseminates performance of VRLA battery is bad, it is liable to cause heat run away when heat accumulates. When temperature exceeds 25oC, the battery life will decrease half per 10oC temperature raise. t25=tT x 2(T25)/10 Notes tT the actual ambient temperature; tT is designed life at T ambient temperature t25 is designed life at 25oC ambient temperature Above-mentioned formula can be used during 10oC-40oC For example, the designed life of battery at 25oC is 10 years, when battery operates at 35 10oC, the actual life is only 5 years.
