(6 cell)
1,2
Voltage (V dc)
Terminal
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.
