Product identity

The CyberPower RB1280X2B is a two-pack replacement battery cartridge containing two sealed lead-acid units rated at 12V and 8Ah each. It is built specifically to restore runtime in the CP1500PFCLCD uninterruptible power supply.

Who it suits

This cartridge suits owners of the compatible UPS whose internal batteries have weakened or failed and who want a user-installable, maintenance-free solution. It does not suit buyers needing a different voltage, capacity, or form factor for other UPS models or standby power applications.

Build integration

The pre-assembled cartridge slides into the UPS battery compartment without tools and its leak-proof casing protects surrounding electronics. Reusable packaging is included so the depleted batteries can be returned to a recycling centre. Operating limits are 0 to 40 degrees Celsius and 0 to 90 percent humidity non-condensing.

Questions about this item

Must I already own a CyberPower CP1500PFCLCD UPS for this cartridge to fit?

Yes, the RB1280X2B is built specifically for the CP1500PFCLCD model and will not install in other units.

Can I keep the original depleted batteries inside the UPS while adding this cartridge?

No, the cartridge replaces the internal batteries entirely; the old cells must be removed before the new cartridge is inserted.

How do I confirm the cartridge is working after installation?

Power on the UPS and check that the LCD shows a full charge status and runs a self-test without reporting a battery fault.
