WARNING 
Altering the default temperature parameters could cause serious property or personal damage. Contact your battery manufacturer to clarify the correct temperature parameters for your specific batteries.
NOTE: Temperature parameters refer to the temperature measured at the temperature sensor, not the temperature of the charger. In this manual all temperatures will be referenced in degrees in Celsius (°C). The user selectable range for battery temperature parameters is
Minimum Charge Temperature: The default is 0ºC
The lowest temperature of the sensor in which the charger will continue charging. If the temperature sensor falls below the minimum charge temperature, the charger will enter standby mode, and cease to charge.
CAUTION 
Charging batteries below 0°C can be potentially dangerous. Internal battery liquid can freeze and charging a frozen battery could cause serious property or personal damage. Contact your battery manufacturer for minimum safe charging temperature for your batteries before altering.
Maximum Charge Temperature: The default is 50ºC
The highest temperature of the sensor in which the charger will continue charging. If the temperature sensor increases above the maximum charge temperature, the charger will enter standby mode, and cease to charge.
CAUTION 
Charging batteries above 50°C can be potentially dangerous. Contact your battery manufacturer for the maximum safe charging temperature for your batteries before altering.
Battery Temperature Compensation (Tempco)
Battery temperature compensation is output voltage regulation based on battery temperature variances. Since batteries can see extreme temperature differences it is important to regulate output voltage with temperature. A battery in a freezing environment should not be charged the same as a battery in a hot environment. The P12 Battery Charger
is set at a baseline of 25°C. Every degree variance from this baseline will result in a voltage variance on all outputs. For every degree above 25°C the charger will reduce all output voltages by the value defined in Battery Tempco. For every degree below 25°C the charger will increase all output voltages by the value defined in Battery Tempco. For example, with the default Battery Tempco set to
CAUTION 
Altering the battery temperature compensation value incorrectly can cause adverse effects on your battery, by potentially reducing its life. Contact your battery manufacturer to find out the specific temperature compensation parameters for your batteries.
