BATTERY TEMPERATURE COMPENSATED VOLATGE SET POINT
The temperature of a battery has an impact on the recharging process—in higher ambient tem-
peratures, the regulation set points (Absorb & Float) need to be reduced to prevent overcharging
of the batteries. In lower ambient temperature conditions, the voltage regulation set points need
to be increased to ensure complete recharging of the batteries.
The default charger settings of the MX60 are based on typical lead acid battery systems. Always
ensure that the Absorb & Float voltage regulation set points are set to the recommended battery manu-
facturer' s recharging regulation voltages.
Non-Battery Temperature Compensated System
If a battery remote temperature sensor is not available the Absorb and Float voltage regulation set
points can be adjusted for the expected weather conditions. The following table shows the appro-
priate adjustments for both Absorb and Float voltage regulation set points for weather conditions
above or below 77˚ F / 25˚ C
EXPECTED TEMPERATURE
Average = 95˚ F / 35˚ C
Average = 86˚ F / 30˚ C
--------------------------------------------------------------------------------------------------------------------------------
Average = 68˚ F / 20˚ C
Average = 59˚ F / 15˚ C
Battery Temperature Compensated System
A battery remote temperature sensor (RTS) will automatically compensate the Absorb & Float
voltage relative to the Absorb and Float set points in the Charger menu. Please reference page 38
of this manual for adjusting the upper and lower battery compensated limits.
