Battery Temperature Sensor
This unit is supplied with one battery temperature sensor. This sensor communicates the
temperature of the battery to the charger and is required to access the charger’s voltage
temperature compensation, batttery over temperature alarm and equalize cycle functions.
BATTERY TEMPERATURE SENSOR CONNECTION
This unit is equipped with 2 RJ45 Telephone Jack connector to connect to up to two Analytic
Systems battery temperature sensor(s).
There are multiple ways to install the sensor at the battery. Regardless of which method you
use, the sensor must be rmly secured to the battery. The sensor should not lose physical
contact with the battery at any point in the charging cycle.
To install the sensor at the battery, you may:
• Slide the sensor between the side of the battery and wall of the battery platform so it
sits ush.
• Place the battery so it is sitting on top of the sensor to hold it in place.
• Apply a small amount of silicone RTV sealant to the sensor and stick it to the top of the
battery.
VOLTAGE TEMPERATURE COMPENSATION
Heat is a normal by-product of the charging cycle. However, excessive heat can cause
overcharging, damaging the battery. With a battery temperature sensor installed, your battery
charger will automatically reduce the charging voltage to compensate for rising temperature.
The ambient battery temperature is set to 77°F (25°C). For each degree above 77°F (25°C),
the charger will reduce the charging voltage by a small amount. See Specications for
the temperature compensation coefcient specic to your unit. You can adjust the voltage
temperature compensation and the temperature compensation range using Analytic System’s
free-to-download software PowerWizard.
