Step 5: Connecting the Battery Temperature Sensor (BTS)
Installing a battery temperature sensor (BTS) extends the life of a battery by
preventing overcharging in warm temperatures and undercharging in cold
temperatures. With a BTS monitoring the battery temperature, the voltage
delivered to the battery is adjusted according to the battery’s actual
temperature.
The BTS has a self-adhesive backing and attaches to the side of the battery.
A 25-foot (7.6 m) cable is supplied with the BTS.
Mounting Options
You can mount the BTS in one of two ways:
• Mounting the sensor to the negative battery post allows the internal
battery temperature to be sensed and provides the most accurate
results.
• Attaching the sensor to the side of the battery using the self-adhesive
backing also provides good results in most situations.
