2. Remove the battery pack and measure the voltage between battery terminals 1(-) and 5(+).
See the following figure :
Terminal
Voltage (V dc)
1
Ground(-)
5
+0V ~ +12.6V
(6 cell)
Note
Charging will take at least 3 hours.
3. If the voltage is still less than +11.1 V DC after recharging, replace the battery.
4. If the voltage is more than +11.1 V DC, measure the resistance between battery terminals 1 and 2.
The resistance must be 2 to 4
㏀ (
typically 3
㏀
).
5. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.
