Replacement battery kit for CyberPower UPS

The RB1290X4F supplies four 12 V 9 Ah sealed lead-acid cells in a pre-assembled cartridge. It is designed to restore runtime to compatible CyberPower UPS units whose original batteries have weakened or failed. The leak-proof construction eliminates the need for fluid maintenance. Installation follows the included instructions and requires no special tools.

Runtime limited by UPS load and battery age

Each 12 V 9 Ah cell delivers a fixed energy capacity that the UPS converts into backup time based on the connected load. Heavier loads reduce available minutes; lighter loads extend them. The sealed lead-acid chemistry gradually loses capacity over time and with repeated deep discharges, so runtime will decline as the batteries age. The cartridge is rated to meet or exceed the original manufacturer specifications.

Verify exact UPS model before ordering

This cartridge fits only the CyberPower models listed in the compatibility list, including PR1500LCDRTXL2U, PR2200LCDRT2U and PR3000LCDRTXL2U variants. Units with different model numbers, even from the same series, may use a different battery arrangement or connector. Confirm the model label on your UPS matches one of the supported part numbers. The package includes recycling information for returning the expired batteries.

Questions about this item

Should I choose the four-pack or look for a different capacity for my PR2200LCDRT2U?

The RB1290X4F provides exactly four 12V 9Ah batteries, which is the quantity and rating specified for the PR2200LCDRT2U and the other compatible models listed.

What runtime can I expect once the cartridge is installed in a PR3000LCDRTXL2U?

Runtime depends on the load connected to the UPS; the cartridge restores the original 12V 9Ah capacity so the unit will deliver the same backup time it did when new.

Does the cartridge use a standard connector that fits the PR1500LCDRTXL2U without modification?

Yes, the pre-assembled cartridge is designed to plug directly into the PR1500LCDRTXL2U and all other listed models with no wiring changes required.
