Compatible UPS Battery

The GreenTechLLC RB1290X2A is a sealed lead-acid replacement battery built for the CyberPower OR1000PFCLCD UPS. It delivers a combined 24 V output from two 12 V cells rated at 9 Ah each. The unit is tested and charged before shipping so it can be installed immediately. It suits administrators who need a direct drop-in replacement for the original RB1290X2A pack.

Build and Connections

The black enclosure measures 5.1 by 3.7 by 5.9 inches and weighs 12 lb, matching the footprint of the OEM battery. Standard F2 terminals provide the same plug-in interface used by the OR1000PFCLCD, so no wiring changes are required. The rigid ABS case resists vibration in rack or tower orientations. No additional mounting hardware is included because the UPS chassis secures the pack.

Pre-Installation Checks

Verify that your UPS is the CyberPower OR1000PFCLCD or lists RB1290X2A as the replacement part number. Confirm the existing battery bay can accept the stated dimensions before ordering. Ensure the UPS is powered off and disconnected from mains before swapping the pack. This battery is not compatible with other CyberPower models or third-party UPS units.
