PowerWarehouse 12 V 5 Ah UPS Battery

This 12 V 5 Ah sealed lead-acid battery replaces the APC RBC43 cartridge number 43. It fits the SUA3000R2X145 unit and is built for maintenance-free operation in rack-mount UPS systems. The battery ships new and ready for immediate installation.

Installation fits the cartridge bay without tools

Slide the replacement cartridge into the UPS chassis until the connectors seat firmly. The most common issue is forgetting to disconnect the UPS from mains power before swapping the cartridge, which can trigger an alarm or trip the internal breaker. Verify polarity markings on the terminals before closing the door.

How can I verify the PowerWarehouse LEADACIDSLA43-07 is working after installing it in my SUA3000R2X145 UPS?

After installation, power on the UPS and check that the front-panel battery indicator shows normal status. Run a self-test from the UPS control panel; a passed test confirms the 12 V 5 Ah cartridge is functioning correctly.

What comes with the LEADACIDSLA43-07 and do I need any extra parts for the RBC43 slot?

The package contains the sealed lead-acid cartridge only. No cables, mounting brackets or additional hardware are included; the unit fits directly into the RBC43 bay of the APC SUA3000R2X145 without extra components.
