• A minimum SOC of 50% allows for approximately 10 weeks between shipment from Cisco’s CM
and a customer checking the SOC.
• SOC decreases approximately 1% per week (due to self-discharge).
• BBU SOC status can be checked using the command line interface (CLI).
• BBUs with less than 50% SOC should be recharged by the system integrator or customer to >50%
SOC.
BBU Storage and Handling Guidelines
The BBU storage and handling guidelines define the BBU shelf life status and how it can be managed at this
stage of the BBU lifecycle:
• The shelf life of a BBU installed in a router with discharge disabled and BBU disabled, or for a spare
BBU, is typically 6 to 12 months.
• Prior to connection to an AC source, the BBU shelf life is a minimum of 21 days.
• When long term storage at a customer site is anticipated, Cisco requires that the BBUs be recharged prior
to expiration of shelf life.
• When AC power is disconnected and the Cisco IR8140H router is removed from service:
• The router switches to DC power supplied by the BBU(s) and remains powered for approximately
8 hours.
• After 8 hours the BBU(s) reaches low voltage disconnect, and the remaining shelf life is a minimum
of 21 days.
• The BBU should be placed in "BBU disable mode" when the router is removed from service in
order to extend BBU shelf life up to 365 + 21 days
• The remaining shelf life depends on the State of Charge prior to removal of AC power and the BBU
being placed in a "BBU disable mode".
• Disabling a BBU at 0% SOC means a minimum remaining shelf life of 21 days, and disabling a
BBU 100% SOC means a maximum remaining shelf life of 386 days.
Recharging a BBU
To recharge a BBU:
Step 1
Connect the router to an AC power source.
Step 2 Enable the BBU.
Step 3 Allow at least 8 hours of charge time per BBU, i.e. for routers with 3 BBUs each, allow 24 hours charge time per router.
Step 4
When the charge time is finished, disable the BBU if the BBU will not be used as backup power for this router.
