What is inside the RB1270X4?
RB1270X4 holds four 12 V blocks, assumed to be two parallel pairs, rated 7 Ah, giving a 24 V bus. CyberPower publishes the cell count. 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 RB1270X4?
Of the 35 models we track, RB1270X4 fits OR1500LCDRM2U. 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 |
|---|---|---|
| OR1500LCDRM2U | 1500 VA / 900 W | all serials |
Which bare cells replace the RB1270X4?
Replace RB1270X4 with four 12V 9 Ah F2 (same case as 7 Ah) cells and reuse the factory harness. CyberPower lists 8.27 x 2.72 x 12.92 in for the pack. 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 RB1270X4?
We can't recommend LiFePO4 for RB1270X4. The bus wiring is unverified, and 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 RB1270X4 cost against bare cells?
RB1270X4 lists at $264. Four bare cells cost about $139.76 at a non-Amazon single-unit reference price, a saving of roughly 47%. 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 RB1270X4 MSRP: $264. Typical Commodity Bare-Cell Band (Non-Amazon Reference): about $139.76 for 4 x CSB HR1234WF2. Reuse your factory wire harness to save about 47% against the OEM cartridge MSRP.
