Compatible CyberPower UPS Kit

This RefurbUPS kit replaces CyberPower RB1290X4A cartridges in compatible uninterruptible power supplies. It ships as a complete four-battery set ready for immediate installation. Small-business and home-office users can restore backup runtime without sourcing individual cells.

Four 12 V 9 Ah SLA cells

The package contains four sealed lead-acid batteries rated at 12 volts and 9 ampere-hours each. This capacity determines whether the kit matches the original cartridge specification. Verify the voltage and ampere-hour rating on your existing unit before purchase.

Drop-in cartridge replacement

The batteries are pre-wired to fit the original cartridge housing, so no soldering or custom cabling is required. Installation instructions are included to guide the swap. The kit weighs 28 units, so ensure the UPS chassis can accommodate the mass. Buyers needing a different voltage or higher capacity should look elsewhere.

They use the standard F2 quick-disconnect terminals found on CyberPower RB1290X4A cartridges.
