Battery Backup Capacity
Battery backup capacity is defined 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 first time. The first 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 flushed.
