Compatible Replacement for APC SU450

This twin-pack supplies two 12 V lead-acid cartridges built to fit the APC SU450 uninterruptible power supply. Each unit matches the original specifications so the UPS can resume normal runtime after a battery swap. The set is intended for administrators maintaining desktop or small-server backup power.

Simple Front-Access Swap

Installation requires opening the UPS front panel, disconnecting the old blocks and connecting the new ones in the same orientation. The only common issue is forgetting to tighten the terminal bolts, which can cause high resistance and early shutdown under load.

Questions about this item

How can I confirm the PowerWarehouse 2XRBC5SLA53 cartridge is working after installing it in my APC SU450 UPS?

The UPS will run a self-test and show normal battery status with no replace-battery indicator lit, confirming the 12 V cartridge is operating correctly.

What comes in the 2-pack and do I need any extra cables or hardware to fit the APC SU450?

The box contains two 12 V lead-acid battery cartridges labelled #53; they connect directly to the SU450's internal terminals so no additional cables or hardware are required.
