Battery & Battery Charger Query Test (#5)
This test queries the SYSAM in the PPN or the EPN Maintenance circuit pack in
an EPN for the status of the battery pack and battery charger, and reports the
result. In a DC-Powered system, this test should never fail. During this test, the
status LED on the battery charger is lit and extinguished if the status of the
battery charger is reported as normal. This event is a result of checking that the
battery charger is connected.
