When to Replace the Backup Battery
When the backup battery nears the end of its three year life, the SFA OS will generate an alert that
the replacement date is eminent in the event log as well as the output of
SHOW UPS ALL
(Figure 1).
A child fault will also appear in
SHOW SUB FAULT.

The status of the battery’s charge can also be determined visually by removing the controller and
turning it upside down to access the battery’s test button and LEDs (Figure 2).
