CyberPower RB1260X2A teardown

What is inside the RB1260X2A?

RB1260X2A holds two 12 V blocks wired in series rated 6 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 RB1260X2A?

Of the 35 models we track, RB1260X2A fits none of the 35 models we track. 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.

Which bare cells replace the RB1260X2A?

Replace RB1260X2A with two 12V 5 Ah F2 cube cells and reuse the factory harness. CyberPower lists 180 x 70 x 107 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 RB1260X2A?

We can't recommend LiFePO4 for RB1260X2A. The tray is only 90 mm long, and the LiFePO4 pack we checked is about 150 mm. 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 RB1260X2A cost against bare cells?

RB1260X2A lists at $116.95. Two bare cells cost about $61.04 at a non-Amazon single-unit reference price, a saving of roughly 48%. 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 RB1260X2A MSRP: $116.95. Typical Commodity Bare-Cell Band (Non-Amazon Reference): about $61.04 for 2 x CSB HR1221WF2. Reuse your factory wire harness to save about 48% against the OEM cartridge MSRP.
