Finally, if placing the sensor on the battery in not practical, place
it where the ambient temperature the battery is exposed to
(surrounded by) can be sensed. Installed properly, your charger
is set to provide your battery with what it needs to out-live and
out-perform any similar battery 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 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 5°C (5°F), the life of the battery will be only 5 years a
50% decrease.
