APC by Schneider Electric SURT192RMXLBP2 Smart-UPS RT 192V Rack Battery Pack
Overview
The SURT192RMXLBP2 is a rack-mounted external battery pack designed for the APC Smart-UPS RT series — specifically the configurations requiring a 192V battery string in a 2-row rackmount form factor. If your runtime requirements exceed what the internal batteries provide, this is the expansion unit that extends your UPS runtime without replacing the main unit or restructuring your rack layout.
The unit occupies 6U of rack space and uses sealed VRLA (Valve-Regulated Lead-Acid) batteries in a black rack-ready enclosure. VRLA chemistry means no water maintenance, no venting concerns in a sealed equipment room, and predictable discharge characteristics that UPS battery management firmware can track accurately. It ships in the Smart-UPS RT series as part of the extended runtime battery ecosystem.
Key Features
- 6U Rack Form Factor: Fits standard 19-inch racks alongside your UPS and other rack UPS battery packs. At 6U, plan your rack space before ordering — this is not a 1U or 2U shelf add-on.
- VRLA Battery Chemistry: Sealed, maintenance-free cells with no liquid electrolyte exposure. Appropriate for enclosed server rooms and telecommunications closets where vented batteries would require additional exhaust infrastructure.
- 2-Row Configuration: The dual-row battery arrangement delivers the 192V string required by compatible Smart-UPS RT UPS models — match the voltage spec of your main UPS before purchasing.
- Rack Mounting Brackets Included: Rack hardware ships in the box, so you are not sourcing mounting hardware separately. Consult the included user manual for torque and rail compatibility guidance.
- All Required Connectors Included: Battery interconnect cabling ships with the unit — verify connector compatibility with your specific Smart-UPS RT model prior to deployment in a data center power environment.
Integration and Compatibility
The SURT192RMXLBP2 is designed for use with APC Smart-UPS RT models that support external 192V battery packs. Verify your UPS model's external battery pack compatibility in the UPS documentation before ordering. Pairing with an incompatible UPS model — even within the Smart-UPS RT line — can result in a non-functional or unsafe configuration. Review your power protection architecture against the UPS unit's supported expansion list.

Frequently Asked Questions
Q: What UPS models is the SURT192RMXLBP2 compatible with?
A: The SURT192RMXLBP2 is designed for APC Smart-UPS RT series UPS units that support external 192V rack battery packs. Verify compatibility with your specific Smart-UPS RT model number using APC's official compatibility documentation before purchasing.
Q: How much rack space does the SURT192RMXLBP2 require?
A: The SURT192RMXLBP2 occupies 6U in a standard 19-inch equipment rack.
Q: Does the SURT192RMXLBP2 require maintenance?
A: No. VRLA (Valve-Regulated Lead-Acid) batteries are sealed and maintenance-free — no water top-offs or periodic venting checks required.
Q: Does the SURT192RMXLBP2 include mounting hardware?
A: Yes. Rack mounting brackets and all required connectors are included in the box.
Q: Can the SURT192RMXLBP2 be used as a standalone UPS?
A: No. This is an external battery expansion pack only. It requires a compatible APC Smart-UPS RT UPS unit to function.
The SURT192RMXLBP2 is a purpose-built external battery pack for the Smart-UPS RT platform — not a universal add-on. The 192V battery string voltage is specific to certain Smart-UPS RT models, and buying this unit without confirming your UPS supports that external battery configuration is the most common install mistake I see. Pull your UPS model number and cross-reference the supported external battery packs list before this goes in a cart.
Technical Highlights:
- VRLA Chemistry: Sealed valve-regulated lead-acid cells require no electrolyte maintenance and are safe for enclosed equipment rooms — no special ventilation infrastructure needed.
- 6U Rack Height: This is a substantial rack footprint. In high-density deployments where rack space is already constrained, factor the 6U into your capacity plan before committing to this expansion path.
- 2-Row Battery Array: The dual-row physical layout delivers the 192V string. This is not interchangeable with single-row or different-voltage APC battery expansion units — the voltage string must match what your UPS expects on its external battery bus.
Deployment Considerations:
- Confirm your Smart-UPS RT model explicitly lists the SURT192RMXLBP2 as a supported external battery pack — voltage compatibility alone does not guarantee firmware and connector compatibility.
- The 26.3H x 43.2W x 73.9D cm physical envelope is larger than many single-row battery packs; verify rack depth clearance, especially in two-post or shallow four-post rack configurations.
Best fit for data center or network operations center deployments running Smart-UPS RT units in extended-runtime configurations — where runtime gaps during extended utility outages are unacceptable and internal batteries alone fall short of the required hold time.
