PowerWarehouse 12V Lead Acid Cartridge #3

The PowerWarehouse 2XRBC3SLA31 is a two-pack of 12V lead acid battery cartridges built as direct replacements for the APC BK450 UPS. It is intended for administrators or home users who need to restore runtime on that specific unit without sourcing original equipment modules.

Capacity and headroom for APC BK450

Each cartridge delivers 12 volts and is guaranteed 100 percent compatible with the BK450, so the UPS regains its factory-rated backup time for typical desktop loads. The pair will not suit larger UPS models that require higher cell counts or different form factors, and they provide no benefit for lithium-ion or modular battery systems.

Questions about this item

Will the 12V lead acid cartridge #3 fit the APC BK450 UPS I already own?

The 2XRBC3SLA31 cartridge #3 is built for the APC BK450, so the two-pack slots straight into that unit.

How can I confirm the new batteries are working after I install them?

After fitting both cartridges, run a self-test from the UPS front panel; a pass with normal runtime shows the 12V cells are delivering full capacity.
