The life expectancy of batteries is temperature dependence at which they are stored
and operated. Batteries should be used in a 70 F (21 C) environment. Consider that
for every 15 F (8.3 C) increase in temperature, the life expectancy is halved.
Exposure to temperatures in excess of 90 F (32 C) should be limited to no more than
30 days per year. Under no circumstances should the battery be exposed to
temperatures over 104 F (40 C) which can lead to thermal runaway, a condition that
damages the battery. Thermal runaway can cause batteries to swell and if the battery
body burst, the hazardous contents may be exposed.
MAINTAINING PROPER AMBIENT TEMPERATURE USUALLY REQUIRES
INSTALLING THE PRODUCT IN A TEMPERATURE CONTROLLED SPACE.
EQUIPMENT ROOMS WITHOUT COOLING SYSTEMS DO NOT GENERALLY
MAINTAIN THE PROPER CONDITIONS FOR GOOD BATTERY LIFE.
