source from the controller to the iBBU. As long as the voltage level stays
below the predefined value, the iBBU provides power for memory. If the
voltage level returns to an acceptable level, the iBBU switches the power
source back to the controller, and all incomplete writes to storage
devices are completed with no data loss.
The maximum ambient temperature for battery packs is 0° C to 45° C.
Note: The temperature of the battery pack is typically 15–20
degrees higher than the ambient temperature during fast
charge. For the fast charge circuit to complete a fast charge
cycle, ambient temperature should be less than 40° C. If
the ambient temperature is greater than 40° C, the fast
charge cycle could terminate prematurely.
