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 sucient 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.
