What is inside the RBC7?
RBC7 holds two 12 V blocks wired in series rated 17 Ah, giving a 24 V bus. APC titles it "Smart-UPS Line Interactive, 24V 17Ah". We inferred the count from its voltage and size. Both blocks carry the same current and should be replaced together. Check the label on your old blocks before ordering a replacement.

Which UPS models use the RBC7?
Of the 35 models we track, RBC7 fits SMT1500C. 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 |
|---|---|---|
| SMT1500C | 1440 VA / 1000 W | all serials |
Which bare cells replace the RBC7?
Replace RBC7 with two 12V 18 Ah nut and bolt cells and reuse the factory harness. Sized from the CSB GP12170NB 17 Ah nut-and-bolt block. A reseller confirms the terminal type, so no guesswork is needed. Keep the old harness, because bare cells ship without leads.
Can LiFePO4 replace the RBC7?
We can't recommend LiFePO4 for RBC7. This pack uses nut-and-bolt terminals, and the LiFePO4 pack we checked has F1 tabs. 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 RBC7 cost against bare cells?
RBC7 lists at $392. Two bare cells cost about $120.94 at a non-Amazon single-unit reference price, a saving of roughly 69%. The reference is a CSB block at one store, and it is not an Amazon price. Reusing the harness is what makes this work.
Official RBC7 MSRP: $392. Typical Commodity Bare-Cell Band (Non-Amazon Reference): about $120.94 for 2 x CSB GP12170NB. Reuse your factory wire harness to save about 69% against the OEM cartridge MSRP.
