Battery cartridge contents

The RB1270X4H cartridge holds four 12V 7Ah sealed lead-acid batteries in a pre-assembled housing. It is built to match or exceed the original specifications for compatible CyberPower UPS units. The leak-proof design removes any need for fluid maintenance. Reusable packaging is included for returning spent batteries to a recycling centre.

Who this suits and who it does not

This cartridge fits owners of the PR750RTXL2U, PR1000RT2U, PR1000RTXL2U, PR1000RT2UN or BP48VP2U01 models who need to replace aged or failed internal batteries. Buyers with different UPS models or voltage requirements cannot use this kit. Anyone needing a different battery count, capacity or chemistry should look elsewhere.

Questions about this item

What comes inside the RB1270X4H cartridge and what must be sourced separately?

The cartridge contains four pre-wired 12V/7Ah sealed lead-acid batteries, installation instructions and recycling information; no extra cables or tools are required for the swap.

My UPS is a PR1000RTXL2U — is the RB1270X4H the correct replacement kit?

Yes, the RB1270X4H is listed as compatible with the PR1000RTXL2U as well as the PR750RTXL2U, PR1000RT2U, PR1000RT2UN and BP48VP2U01 models.

How does the 48 V total voltage from the four 12 V blocks translate to runtime on a PR1000RT2U?

The four 12 V blocks deliver the 48 V DC bus the UPS expects, restoring the original 7 Ah capacity so runtime returns to the level the unit had when new.
