4 Replacing Battery Backup Units Intel recommends that you replace each BBU once a year or after 500 recharging cycles, whichever comes first. The battery pack has one year warranty. After you install a new BBU, use one of the Intel configuration utilities to reset the battery recharge cycle counter to zero. For instructions, see "Monitoring the BBU with the Intel® RAID BIOS Configuration Utility" on page 11. Disposing of Battery Backup Units Warning: Do not damage the battery pack in any way. Toxic chemicals can be released if it is damaged. The material in the battery pack contains heavy metals that can contaminate the environment. Federal, state, and local regulations prohibit the disposal of rechargeable batteries in public landfills. Be sure to recycle old battery packs properly. Intel would like to remind you that you must comply with all applicable battery disposal and hazardous material handling laws and regulations in the country or other jurisdiction where you are using the BBU.
