Certified OEM Replacement Cartridge

The CyberPower RB1290X4 is a pre-assembled battery cartridge containing four sealed lead-acid units rated at 12V 9AH each. It is certified to meet or exceed original manufacturer specifications for the CyberPower OR2200LCDRM2U UPS and is designed for user installation without special tools.

Sustained Load Behaviour

Under continuous discharge the sealed lead-acid chemistry delivers stable voltage until the cells approach depletion, avoiding the sharp drop-off seen in short-burst tests. The maintenance-free, leak-proof construction means the pack can remain installed for the full service interval without electrolyte checks or top-ups.

Upgrade Context

This cartridge replaces the original internal battery set when runtime has fallen below acceptable levels or the UPS reports a battery fault. The jump is worth it when the existing pack no longer holds sufficient charge for the connected load, and the reusable packaging simplifies returning the expired cells for recycling.

Questions about this item

How much heat does the RB1290X4 generate during continuous operation?

Sealed lead-acid batteries produce minimal heat under normal float charging; the cartridge is designed to operate within the UPS enclosure without additional cooling.

What must I already own for the RB1290X4 to work?

A CyberPower OR2200LCDRM2U UPS is required; the cartridge is a certified OEM replacement built specifically for that model.

Will the RB1290X4 fit alongside the original battery trays in my OR2200LCDRM2U?

Yes, the pre-assembled cartridge matches the factory dimensions of 2.72" x 8.27" x 12.92" and slides into the existing battery compartment.
