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 that there is sufficient energy. The operation runs automatically, and causes
no impact to the 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.
Initiating The Battery Delay Learn Cycle
Does my controller support this feature? See Supported Features.
The controller firmware automatically initiates the battery learn cycle every 90 days. Although you cannot stop the firmware
from running the learn cycle, you can delay the start time of the learn cycle for up to seven days.
