Battery Pack - Life and Data Retention Time
The Intel
®
RAID Smart Battery software utilities use a counter to show the number of times the
battery has been recharged. When replacing the Intel
®
RAID Smart Battery AXXRSBBU7, the
Intel
®
RAID BIOS Console 2 utility can be used to reset the counter to zero for the new battery.
Intel recommends that you replace the Intel
®
RAID Smart Battery AXXRSBBU7 once a year or
after 500 recharging cycles, whichever comes first. The Smart Battery has a one-year warranty.
The Smart Battery can retain data for about 72 hours (three days). This is approximate and can
vary due to several factors, including charge level of the battery pack, the battery load, the
ambient temperature, the age of the battery, and the number of discharge cycles associated
with the battery.
