Which UPS models use the RB1270X4F?
Of the 43 models we track, RB1270X4F fits PR1000LCDRT2U, PR1500LCDRT2U. 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 |
|---|---|---|
| PR1000LCDRT2U | 1000 VA / 900 W | all serials |
| PR1500LCDRT2U | 1500 VA / 1350 W | all serials |
Which bare cells replace the RB1270X4F?
Replace RB1270X4F with four 12V 9 Ah F2 (same case as 7 Ah) cells and reuse the factory harness. CyberPower lists 206 x 66 x 315 mm for the pack. 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 RB1270X4F?
We can't recommend LiFePO4 for RB1270X4F. Four independent BMS boards in one 48 V series string 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 RB1270X4F cost against bare cells?
RB1270X4F lists at $281. Four bare cells cost about $139.76 at a non-Amazon single-unit reference price, a saving of roughly 50%. 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 RB1270X4F MSRP: $281. Typical Commodity Bare-Cell Band (Non-Amazon Reference): about $139.76 for 4 x CSB HR1234WF2. Reuse your factory wire harness to save about 50% against the OEM cartridge MSRP.
