Compatible replacement for APC Smart-UPS models

This sealed lead-acid battery cartridge replaces OEM part RBC43 and fits a wide range of APC Smart-UPS rack-mount units including the SMT1000RM1U, SMT2200RM2UC and SMT3000RM2UC series. It delivers a 48 VDC output configured as eight 12 V, 5 A cells and arrives tested, charged and ready for immediate installation.

Sustained load behaviour and recharge profile

The cartridge provides between one and thirty minutes of backup run time depending on the connected load, giving critical equipment a window for safe shutdown during extended outages. After a full discharge the battery recharges in under twenty-four hours, restoring reserve capacity for the next event without requiring manual intervention.

Deciding specification: 48 VDC 8-cell configuration

The single figure that determines fit is the 48 VDC nominal voltage built from eight 12 V cells; UPS units expecting a different voltage or cell count will not accept this cartridge. Buyers whose equipment calls for a 24 VDC or 12 VDC replacement cannot use this part and should verify the voltage requirement before ordering.

Questions about this item

Does the 48 VDC sealed-lead-acid pack generate noticeable heat or fan noise during a full-day runtime?

The cartridge is a passive 48 VDC SLA assembly with no internal fans; any warmth comes from normal charge-discharge cycling inside the UPS enclosure.

Which APC Smart-UPS chassis must already be installed for this RBC43 replacement to connect and operate?

It fits the SMT1000RM1U, SMT2200RM2UC, SMT3000RM2UC and other listed 2U or 1U rackmount models that accept cartridge #43.

Will the 21.0 x 8.5 x 3.2 inch cartridge slide into the same battery bay as an original RBC43 in an older SMT2200R2X106 unit?

Yes, the dimensions and 48 VDC 8 × 12 V 5 A configuration match the OEM cartridge #43 used in that model.
