A "Discharge Test Failure" notification indicates the battery is unable to
power to load for the set duration.
The connected load devices should continue to run normally while the
discharge test is running.
NOTICE
This test must only be done when AC power is present during the
test and for an adequate time after the test to allow for a full
recharging of the battery. Otherwise, the battery may not have
sufficient remaining capacity to power the load during an AC
power outage.
Set Discharge Time:
Set the maximum time for the test in minutes (10–
240 minutes) that the test will run. The default setting is 60 minutes.
Set Discharge Voltage Limit:
Minimum battery voltage which will
terminate the test. The default setting varies based on the Power
Modules installed.

Discharge Test Interval:
Set the time in days (0–180 days) between
automatic discharge tests. Set this time to 0 to disable automatic
discharge tests. The default setting is 0 (Disabled).
Day of Week:
Set the day of the week that the automatically recurring
discharge test should take place or select "Any" to allow a discharge test
to take place on any day of the week. Day of Week takes precedence
over Discharge Time Interval. The default setting is Any.
Start Time
: Set the time of day for an automatically recurring discharge
test to start. The time of time must be entered using 24-hour time format.
The default setting is 00:00.
NOTE: NTP Time Synchronization must be enabled on the Communications
Basic Setup page to enable automatic Discharge Tests.
A discharge test can only be initiated when the battery is fully
charged. If the system is unable to start a Discharge Test at the
selected Start Time, it will attempt again at the same time next day,
or next week if a specific Day of Week is selected.
