automatically if the battery voltage falls too low. This normally occurs
about once a week to top off the charge level; the process does not change
the BBU readiness state.
If the battery is ever discharged through a backup cycle or if the system
power is off for more than two weeks, the battery status changes to
"Charging" the next time the system is powered on. This indicates the
BBU is not able to backup the 3ware RAID controller. When the BBU is
in the charging state, write caching is disabled automatically on all units
attached to the controller.

battery health test or capacity test indicate that the battery is below the
warning threshold (48 hours).
• Failed Battery
Battery" status is displayed if the battery failed the health test or the
battery capacity is below the error threshold (24 hours). The battery must
be replaced.
Battery Voltage.
measures and evaluates the battery voltage continuously. If the voltage falls
outside the normal range, warning or error level AENs are generated. In the
case of a voltage error the BBU status will change to "Fault" and the battery
will be disconnected electronically.
Battery Temperature
BBU measures and evaluates the battery pack temperature continuously. If the
temperature falls outside the normal range, warning or error level AENs are
generated based on the measured temperature. In the case of a temperature
error, the BBU status will change to "Fault" and the battery will be
disconnected electronically.
