External Battery Pack for Smart-UPS

The APC SMX120RMBP2U is a 120 V DC external battery pack designed to extend the runtime of compatible Smart-UPS units. It serves IT managers and facility operators who need longer backup time for critical loads in rack or tower environments. The unit uses maintenance-free sealed lead-acid batteries with suspended electrolyte for spill-proof operation. It is built for indoor use in standard rack enclosures.

Runtime Scales With Connected Load

The pack delivers a 1200 VAh capacity at 120 V DC output, but actual runtime depends entirely on the power draw of the attached UPS and its connected equipment. Heavier loads will deplete the reserve faster, while lighter loads yield proportionally longer support. The battery voltage is fixed at 120 V DC, so it only works with UPS models designed for that DC bus. Ambient temperature and battery age also affect achievable minutes.

Hot-Swap Design With Rack Hardware Included

Hot-swappable battery cartridges allow a trained user to replace cells without powering down the protected equipment. The package includes rack-mounting brackets and an installation guide for 2U rack or tower deployment. The unit weighs 124.25 lbs and measures 26.26 by 17.01 by 3.35 inches, so two people or a lift are usually needed to position it safely. Ensure the target UPS is on the supported compatibility list before installation.

Questions about this item

Which compatible UPS models does this 120 V external battery pack support?

It is designed for SMX2000RMLV2U, SMX2200RMHV2U, SMX2200RMLV2U, SMX3000RMHV2U, SMX3000RMHV2UNC, SMX3000RMLV2U and SMX3000RMLV2UNC units.

What runtime gain does the 1200 VAh capacity deliver in a live system?

The 1200 VAh rating extends battery backup time for the connected Smart-UPS, with actual minutes depending on the load placed on the UPS.

How does the 120 V DC output interface limit use in practice?

The pack supplies 120 V DC only to the listed Smart-UPS models, so it cannot power other voltages or non-compatible equipment.
