Battery Learn Cycle
Learn Cycle is a battery calibration operation 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. To choose manual
battery learn cycles, disable automatic learn cycles.
If you enable automatic learn cyles, you can delay the start of the learn
cycles for up to 168 hours (7 days). If you disable automatic learn cycles,
you can start the learn cycles manually, and you can choose to receive
a reminder to start a manual learn cycle.

1.
Click the
Physical
tab to open the physical view.
2.
Select the BBU icon in the left panel.
3.
