Compatible 1500VA UPS Battery Pack

This two-pack of 12V lead-acid cartridges is built as a direct replacement for the APC Smart-UPS 1500VA. It restores runtime for servers, network gear and workstations that rely on that UPS model. The batteries arrive new and ready to install without modification.

100% compatibility headroom

The pair matches the original 744 cartridge specification, so capacity and voltage align with the factory design. Runtime scales with the connected load; heavier draws will deplete the cells faster than light loads. Units needing a different voltage or form factor cannot use this pack.

Questions about this item

Will the 12 V 1500 VA cartridge fit my existing APC Smart UPS 1500 VA without rewiring?

Yes — the 2XRBC7SLA744 cartridge is built to match the original RBC7 form factor and voltage, so it slides into the same bay and connects to the existing terminals.

How can I confirm the new batteries are delivering full runtime after installation?

Run a self-test from the UPS front panel or management software; a passed test and a runtime reading close to the unit’s original 100 % specification show the pack is working correctly.
