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 cycles, 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.
