TEMPERATURE AND ITS EFFECT ON BATTERIES
Temperature has a direct effect on the life of a battery. The design
life of the battery is based on an average annual temperature of
25°C (77°F). As the temperature increases above 25°C (77°F), the
life of the battery decreases. The chart below shows the effects of
temperature.

For example: If a battery’s design life is 10 years at 25°C (77°F), but
the average battery temperature is 35°C (95°F), the projected life of
the battery is calculated to be only 5 years, [10 years - (10 years X
0.50) = 5 years].
