Temperature sensor
The battery charger has one connector for a
temperature sensor, which is supplied with the battery
charger.
To improve the lifetime of the battery, applied voltages
and current are temperature dependant; therefore,
connect the sensor in such a way that a good thermal
reading is possible. For example, you can either connect
the sensor to the battery tray, or place it between two
batteries (see figure 3.6). If the temperature sensor is not
being used, the slide switch for the temperature sensor
should be set to off.
