Finally, if placing the sensor on the battery in not practical, place it where the ambient temperature the
batteries are exposed to (surrounded by) can be sensed. When properly installed on the battery, your
charger is set to provide your batteries with what they need to out-live and out-perform any similar bat-
tery used in the same application-conditions, by a factor of two (2).
Temperature has a direct effect on the life of a battery. The design life of a 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 bat
-
tery 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 life of
the battery will be only 5 years a 50% decrease.
