Return to Service Checks (Tests)
Follow these steps to check the battery operation prior to returning to or putting in service:
1.
Apply power to the aircraft via master swith, observe proper voltage, typically 13.2
to 14.2 V.
2.
Verify the battery fault LED is off.
3.
Press the LED “push-to-test lens” and observe the LED illuninates.
Aircraft Voltage Monitoring Equipment (if applicable)
The table below shows the recommended user alerts based on voltages when in flight. This
pertains to existing aircraft equipment, and is not applicable if existing low or high voltage
alerts do not exist or are not adjustable.
The low charge level is very different from a lead acid battery, for a lithium battery is
completely drained at approximately 11.5V, and the normal resting voltage is 13.3V.
Note: this table pertains to existing voltage level warning equipment and is NOT associated
with the Fault monitoring LED.
