This new maintenance-free lead-acid battery replaces the RBC11 cartridge for APC SU48RMXLBP units. It restores backup runtime for rack-mounted UPS systems in server rooms and network closets. The cartridge design allows quick hot-swap installation without tools. ||

Not for non-APC UPS or different cartridge models

Buyers who need a battery for another UPS brand or a different APC cartridge number should look elsewhere. This unit does not fit models that require a different form factor or voltage configuration. It is also unsuitable for applications demanding lithium-ion chemistry or user-serviceable cells.

Questions about this item

Will this LEADACIDSLA11-01 cartridge fit alongside my existing APC SU48RMXLBP battery modules?

Yes, it replaces the RBC11 cartridge #11 used in the APC (2)SU48RMXLBP, so it installs directly into the same UPS chassis.

How can I verify the new battery is operating correctly after installation?

Run the UPS self-test from the front panel or management software; a passed test and normal runtime during a brief power pull confirm the replacement is working.
