Important: Don’t restart or shut down your computer during conditioning. Doing

so interrupts the charging cycle and delays the use of the write caches. Repeated

interruptions can prevent the battery from accepting or delivering a full charge.

Battery Charging

During normal operation, the battery is kept fully charged. However, the battery

discharges during a power failure, when the computer is unplugged, and during

shipment of a new computer with a RAID card installed. If the battery loses enough

charge that it can’t provide roughly 72 hours of cache backup, the write caches

are disabled and RAID Utility displays a battery warning status until the battery is

recharged.
