two seconds
The system is powered down, and the cache contains data that has not
yet been written to the drives. Restore system power as soon as
possible to prevent data loss.
If 3.3 V auxiliary power is available, as indicated by LED 2, then data
preservation time is extended. If no auxiliary power is available, only
battery power preserves the data. A fully-charged battery can
normally preserve data for at least two days.
The battery lifetime also depends on the cache module size. For more
information, see the controller QuickSpecs on the HP Product Bulletin
website (http://www.hp.com/go/productbulletin).

The battery pack is below the minimum charge level and is being
charged. Features that require a battery (such as write cache, capacity
expansion, stripe size migration, and RAID migration) are temporarily
unavailable until charging is complete. The recharge process takes
between 15 minutes and 2 hours, depending on the initial capacity of
the battery.

The life expectancy of a battery pack is typically more than three
years.
