Battery Life and Data Retention Time
The Intel
®
RAID Web Console utility displays a counter showing the number of times a
BBU has been recharged. When you replace a BBU, you should run the utility program
and reset this counter to zero for the new BBU. Intel recommends that you replace the
battery pack on the BBU once a year or after 500 recharging cycles, whichever comes
first. Intel provides a one year warranty on the Intel
