GreenTech RB12120X2B 24V SLA Battery

This GreenTech RB12120X2B is a sealed lead-acid replacement battery built for CyberPower Smart App Sinewave PR1000LCD and PR1000LCDTAA UPS units. It delivers a 24 V output from two 12 V, 12 Ah cells wired in series. The pack arrives tested, charged and ready to install.

12 Ah capacity per cell gives standard backup

Each 12 Ah cell provides the energy reserve the UPS expects for typical desktop and networking loads. Runtime scales with the connected load; heavier draws will exhaust the reserve faster while lighter loads extend it. The 24 V string matches the original voltage requirement exactly.

Fits PR1000LCD and PR1000LCDTAA battery compartments

The pack measures 7.72 x 3.94 x 5.94 inches and weighs 18 lb, matching the OEM RB12120X2B form factor for direct drop-in installation. No adapter cables or firmware changes are required. It frees the UPS to resume full backup operation immediately after the swap.

Questions about this item

Will the 24V 12AH x2 SLA set fit inside the CyberPower PR1000LCD without modifying the battery tray?

The pack measures 7.72" x 3.94" x 5.94" and is built to the same form factor as the original RB12120X2B, so it slides into the existing tray without modification.

How can I verify the GreenTech battery is delivering the rated 24VDC after installation?

Power on the UPS and check the front-panel LCD; it should report a battery voltage near 24 V and show the battery status as healthy or fully charged.

Does the box include the connector cables needed for the PR1000LCDTAA, or must I reuse the old ones?

The replacement ships as the two 12 V 12 AH modules only; you will reuse the existing harness and connectors from your CyberPower unit.
