Advanced Battery Management (ABM) extends the life of the battery by shutting off the charger for 28 days
per ABM cycle and therefore reduces grid corrosion in the battery caused by trickle charging over long periods
of time. Disabling ABM means the battery chargers run in constant charge mode and never turn off. The
battery test period is every three ABM cycles.
NOTE It is not recommended to perform a battery discharge test more often than 90 days.

The battery test will run only in Rest Mode and if ABM is enabled. The tests frequency can be modified. During
the test, the UPS transfers to Battery mode and discharges the batteries for 25% battery time remaining.
NOTE Battery mode is not displayed and battery low alarm does not activate during a battery
test.
The battery test may be postponed due to bad conditions, or failed if battery is not ok.

During discharge, the low battery alarm is activated if the remaining runtime goes below 3 minutes or less than
