Direct replacement for SMX1500RM2U UPS

The APC APCRBC115 is a new sealed lead-acid battery cartridge designed to restore original runtime to compatible Smart-UPS units. It fits the SMX1500RM2U 1500VA model and related SKUs without modification. The spill-proof, maintenance-free construction allows safe handling during installation. This cartridge returns the UPS to factory backup specifications.

Suits administrators refreshing a single rackmount

IT teams responsible for one or two APC Smart-UPS SMX1500RM2U units will find this cartridge a direct fit. Environments that require extended runtime beyond the factory cell count should look at external battery packs instead. Buyers needing lithium chemistry or hot-swappable modules for a different UPS family will not be served by this part. The 26.05 lbs weight means one person can lift it, but plan for proper disposal of the old pack.

Delivers minutes of runtime under sustained load

At full load the cartridge provides 0.08 hour of backup, while half load yields 0.23 hour. These figures reflect continuous discharge until shutdown, not a brief surge capacity. Voltage remains stable through the discharge curve because the sealed lead-acid cells are matched to the UPS charger profile. Expect the same thermal behaviour as the original factory battery during prolonged outages.
