1. Indicates how long the battery can hold data in the controller's memory in case of accidental system shutdown.
2. The controller's performance is not affected during the battery's learn cycle.
Input example:
storcli /c0/bbu set bbuMode=2
storcli /cx/bbu set learndelayinterval=<value>
This command sets the learn delay interval for the BBU in hours. The value must be between 0 to 168 hours (7 days).
Input example:
storcli /c0/bbu set learnDelayInterval=30
storcli /cx/bbu set powermode=sleep
This command places the battery in low-power storage mode. The battery automatically exits this state after
5 seconds.
Input example:
storcli /c0/bbu set powermode=sleep
storcli /cx/bbu set writeaccess=sealed
This command seals the gas gauge EEPROM write access.
Input example:
storcli /c0/bbu set writeaccess=sealed
storcli /cx/bbu set writeaccess=sealed
This command seals the gas gauge EEPROM write access.
Input example:
storcli /c0/bbu set writeaccess=sealed

48 hours of retention at 55 °C, 1-year Service Life.
Same as the description for BBU mode 5. The BBU mode 6 enables you to receive events when the battery
capacity reaches suboptimal and critical thresholds.
NOTE BBU modes are supported on any iBBU08/09 bbu/controller combo
and later-generation controllers.
NOTE Use the set writeaccess=sealed command at manufacturing
time.
NOTE Use the set writeaccess=sealed command at manufacturing
time.
