Replacement battery for select CyberPower UPS

This 24 VDC sealed lead-acid pack replaces the RB1280X2A in CyberPower Intelligent LCD UPS models CP1350AVRLCD, CP1500AVRLCD and CP1500AVRT. It contains two 12 V, 9 Ah cells and arrives tested, charged and ready to install. Dimensions are 7.87 x 2.56 x 5.91 inches and the unit weighs 11 lb.

Who this suits and who should look elsewhere

The pack fits owners of the listed CyberPower UPS units who need a direct drop-in replacement. It is not for users whose UPS requires a different voltage, capacity or form factor, nor for anyone seeking a lithium-based alternative.

Critical specification: 24 VDC 9 Ah sealed lead-acid

The 24 VDC, 9 Ah sealed lead-acid chemistry determines whether the battery matches the UPS charging circuit and runtime expectations. Verify the original part number and serial-number prefix before ordering.
