10.21 Battery Learn Cycle
Learn cycle is a battery calibration operation that is performed by the controller periodically to determine the
condition of the battery. You can start battery learn cycles manually or automatically. To choose automatic battery
learn cycles, enable automatic learn cycles.
If you enable automatic learn cycles, you can delay the start of the learn cycles for up to 168 hours (7 days). If you
select the Generate an event to remind me when to start a learn cycle manually check box in the Set Automatic
Learn Cycle Properties dialog, the automatic learn cycle gets disabled and an event is generated to remind you when
you need to start a learn cycle.
