What is inside the RBC24?
RBC24 holds four 12 V blocks, assumed to be two parallel pairs, rated 9 Ah, giving a 24 V bus. APC doesn't publish the cell count, so it comes from cross-references. All the blocks should be replaced together. Check the label on your old blocks before ordering a replacement.

Which UPS models use the RBC24?
Of the 43 models we track, RBC24 fits SUA1500RM2U. That list comes from the manufacturer's pages, and they sometimes disagree with reseller listings. Where a model splits by serial number, its UPS page shows which prefix takes this cartridge, so check your label before you order.
| UPS | Rating | Serial condition |
|---|---|---|
| SUA1500RM2U | 1500 VA / 980 W | all serials |
Which bare cells replace the RBC24?
Replace RBC24 with four 12V 9 Ah F2 cells and reuse the factory harness. Battery Mart lists 13.50 x 8.50 x 3.26 in for the tray. The terminal comes from a retailer cross-reference or inference, so check your old cell first. Keep the old harness, because bare cells ship without leads.
Can LiFePO4 replace the RBC24?
We can't recommend LiFePO4 for RBC24. Four independent BMS boards in one pack multiply the balance risk. Showing a link would mean guessing about fit. Buy the lead-acid cell or a factory LiFePO4 UPS instead, and see our method page for how we test fit.
How much does the RBC24 cost against bare cells?
RBC24 lists at $789. Four bare cells cost about $139.76 at a non-Amazon single-unit reference price, a saving of roughly 82%. The reference is a premium CSB block at one store, and it is not an Amazon price. Reusing the harness is what makes this work.
Official RBC24 MSRP: $789. Typical Commodity Bare-Cell Band (Non-Amazon Reference): about $139.76 for 4 x CSB HR1234WF2. Reuse your factory wire harness to save about 82% against the OEM cartridge MSRP.
