Replacement Cartridge for UPS Systems

The CyberPower RB1270B is a 12V 7AH sealed lead-acid battery cartridge designed to replace the original RB1270 pack. It arrives pre-assembled and certified to meet or exceed the original manufacturer specifications. This unit restores backup runtime for compatible CyberPower UPS models without requiring soldering or wiring. It is not for users who need a higher-capacity pack or a different voltage platform.

Leak-Proof Sealed Lead-Acid Operation

The cartridge uses leak-proof sealed lead-acid cells that operate without venting during normal charge and discharge cycles. No liquid electrolyte can escape, so the pack runs silently and requires no periodic maintenance. Power draw is limited to the UPS charging circuit, and thermal output stays low enough for enclosed battery compartments. Buyers who want lithium chemistry or hot-swappable modules cannot use this cartridge.

Drop-In Fit for CP585LCD and CP600LCD

The RB1270B slides directly into the battery bay of the CP585LCD and CP600LCD units, using the existing connector and mounting points. Installation frees the UPS from a depleted pack and returns it to full backup capability in minutes. No tools or firmware updates are required. Builders who need a cartridge for other UPS models or a user-replaceable tray design must select a different part.

Questions about this item

How do I install the RB1270B cartridge into my CP600LCD UPS?

Power down the UPS and unplug it, open the battery door, disconnect the old cartridge leads, insert the pre-assembled RB1270B unit, reconnect the leads observing polarity, close the door, then power the UPS back on.

When will the sealed lead-acid cells in the RB1270B need replacement?

Expect three to five years of service; replace the cartridge when runtime drops noticeably or the UPS reports a battery fault.

What runtime limit appears first during a prolonged outage with the 7AH pack?

The 7AH capacity determines total energy; runtime ends when the stored charge is depleted, which occurs sooner under heavier loads.
