NOTE:
A new or replaced BBU takes about 12 hours to charge to its full
capacity.
NOTE:
The life expectancy of a BBU is more than one year. However,
batteries’ life span can fluctuate depending on how many times
batteries are charged. An installation date record is kept in the
EEPROM embedded in the battery module. After reaching the
one-year life expectancy, system firmware will automatically notify
an administrator. Follow the procedures in
Section 5.4
to replace
a BBU that is not able to hold charge.
