Test battery option
If you select option 7 (Test battery) on the System Power Control Network (SPCN)
display, the following display appears confirming that you requested the battery
interface test. You have the chance to cancel the test by pressing the F12 (Cancel)
key.
Selecting this option causes the system to perform a battery interface test and
schedule a battery capacity test in 24 hours. Because the system automatically tests
the batteries every 3 months (if enabled), you should use this option only after
replacing a battery power unit. This option is valid for only those units that
contain a battery power unit and is not valid for a frame.
Note: Excessive testing of the battery will shorten its useful life.
When the test completes, the following display appears. A message that describes
the results displays on line 24.
