This sealed lead-acid cartridge replaces the APC SU48BP RBC11 unit. It arrives ready to install without fluid handling or priming. The maintenance-free design suits rack-mounted UPS systems that require a direct drop-in module.

Suitable for APC SU48BP owners

Buyers with a different UPS model or a cartridge number other than 11 should verify compatibility before purchasing. This unit does not fit cabinets that call for a different voltage or form factor.

Questions about this item

Which UPS models accept the LEADACIDSLA11-32 cartridge?

It is built as a direct replacement for the APC SU48BP and the RBC11 cartridge, so those UPS units will accept it.

Can I mix this new cartridge with older batteries already in my SU48BP?

Mixing a fresh lead-acid cartridge with aged cells is not recommended; replace the full set at once for balanced runtime.
