This temperature sensor offers linear charging voltage increase as the battery ambient temperature decreases below approximately 80 degrees F. If the battery is in the passenger or engine compartments, it is sufficiently warmed to make this sensor of little value. If the battery is in a compartment with no environmental control, on an aircraft that flies in very cold environments (extreme latitudes or high altitudes), then this sensor is recommended.

There is no temperature voltage correction above 80 degrees F.
