Restore CyberPower UPS runtime

The RB1290X4H cartridge contains four 12V 9Ah sealed lead-acid batteries designed to replace depleted cells in compatible CyberPower UPS units. It is intended for administrators and home-office users who need to return their backup power system to full runtime without replacing the entire UPS.

Leak-proof sealed cells require no fluid

Each battery is a maintenance-free sealed lead-acid design that never needs electrolyte top-ups. The pre-assembled cartridge fits directly into the UPS chassis, eliminating loose-cell handling and reducing installation time during routine battery refresh cycles.

Reusable packaging simplifies recycling

The shipment includes a return-ready box for sending expired batteries to an appropriate recycling centre, along with printed instructions and recycling guidance. An eighteen-month warranty covers the cartridge against defects in materials and workmanship.

Questions about this item

How do I install the RB1290X4H cartridge in my OR2200PFCRT2U UPS, and which step do people often miss?

Power down the UPS, remove the front panel, disconnect the old battery wiring harness, slide in the pre-assembled cartridge, reconnect the harness securely, and replace the panel — the step most often missed is firmly reseating the harness connector so the UPS detects the new batteries.

What maintenance or replacement will the four 12V 9Ah sealed lead-acid batteries need later?

The sealed design eliminates fluid checks; plan to recycle the whole cartridge after three to five years or when runtime drops noticeably, using the reusable packaging supplied for return to a recycling centre.

What limit appears first when the OR2200PFCRT2U runs on this cartridge during a long outage?

The 9Ah capacity of each 12V cell determines total runtime; once the stored energy is depleted the UPS will shut down, so the amp-hour rating is the first hard limit under sustained load.
