TEMPERATURE COMPENSATION
MULTI XS 25000, XS 25000, MULTI XT 14000 and XT 14000 have a sensor cable placed together with the battery cables. The units will automatically adjust the charging voltage if the temperature deviates from +25 C. A high temperature lowers the voltage and freezing conditions is handled by higher voltage.
The temperature is best measured on or very close to the battery. Therefore always place the sensor as close to the battery as possible when charging. The sensor cable could be prolonged or cut to length with the same functionality. A

*) Back current drain is the current that the charger drains from the battery if the AC cord is disconnected.
**) The quality of the charging voltage and charging current are very important. High current ripple heats the battery and ages the positive electrode. High voltage ripple can damage other equipment connected to batteries. The battery chargers from CTEK produces very high quality voltage and current with low ripple.
***) IP 44 cannot be guaranteed if the charger is not positioned horizontally with the long side or top side turned up.
