The controller firmware automatically initiates the Learn cycle every 90 days.
You can, however, delay the start time of the Learn cycle for a further seven
days, after which the firmware automatically initiates the Learn cycle. For
more information, see
Battery Delay Learn Cycle .
NOTE: The Learn cycle cannot be performed while the battery is charging. If either
a user or the controller firmware initiate the Learn cycle while the battery is
charging, then the battery Learn State displays Requested. When the battery is fully
charged, the Learn cycle begins.
Battery Transparent Learn Cycle
The PERC H710 and PERC H810 controllers support Transparent Learn
Cycle (TLC), a periodic operation that calculates the charge that is remaining
in the battery to ensure there is sufficient energy. The operation runs
automatically, and causes no impact to system or controller performance. The
controller automatically performs TLC on the battery to calibrate and gauge
its charge capacity once every 90 days. The operation can be performed
manually, if required.
