Battery Backup Capacity

Battery backup capacity is dened as the maximum duration

of a power failure for which data in the cache memory can be

maintained by the battery. The BBM’s backup capacity varied

with the memory chips that installed on the SAS RAID controller.

Capacity Memory Type Battery Backup Duration (Hours)

512MB DDR2 Low Power (14.6mA) 72Hr - 76Hr

Operation

1. Battery conditioning is automatic. There are no manual pro-

cedures for battery conditioning or preconditioning to be per-

formed by the user.

2. In order to make sure of all the capacity is available for your

battery cells, allow the battery cell to be fully charged when

installed for the rst time. The rst time charge of a battery cell

takes about 24 hours to complete.

Changing the Battery Backup Module

At some point, the LI-ION battery will no longer accept a charge

properly. LI-ION battery life expectancy is anywhere from ap-

proximately 1 to 5 years.

1. Shutdown the operating system properly. Make sure that

cache memory has been ushed.
