Compatible replacement for APC 450AT

This PowerWarehouse 2XRBC3SLA30 pack supplies two 12 V sealed lead-acid cartridges built to match the original APC 450AT specifications. The batteries are guaranteed 100 % compatible with the UPS unit and carry a one-year replacement warranty from the manufacturer. They arrive new and ready for immediate installation in the applicable APC system.

Sealed lead-acid chemistry for stable standby power

The 12 V cells use valve-regulated lead-acid technology that delivers consistent float voltage with minimal self-discharge during extended standby periods. Normal operation produces negligible acoustic noise and low heat output, keeping the UPS enclosure cool without active cooling. Power draw is limited to the UPS charging circuit, so no additional supply capacity is required beyond the original design.

Questions about this item

How do I install the two 12 V cartridges into my APC 450AT without reversing the terminals?

Power off and unplug the UPS, open the battery door, note the red-to-red and black-to-black polarity on the old pack, slide each new cartridge in the same orientation, close the door and restart the UPS.

When should I expect to replace these lead-acid cartridges again?

Typical service life is 3 to 5 years; plan replacement when runtime drops noticeably or the UPS reports a battery fault.
