APC by Schneider Electric SURT192RMXLBP 192V Rack Battery Pack
Overview
The SURT192RMXLBP is a 192V lead-acid rack battery pack purpose-built to extend runtime on APC Smart-UPS RT series uninterruptible power supplies. Occupying 3U of rack space and finished in black, it integrates directly with compatible Smart-UPS RT models to increase the amount of battery capacity available during a power event — giving protected equipment more time to execute an orderly shutdown or ride out a longer outage without a separate external battery enclosure.
For integrators deploying APC by Schneider Electric power protection in communications rooms, security head-end closets, or network equipment racks, this pack adds battery depth without adding a separate UPS chassis. It is designed to be installed alongside the host UPS in a standard 19-inch rack, keeping the footprint consolidated and the wiring internal to the rack.
Key Features
- 192V Lead-Acid Chemistry: The sealed lead-acid battery string operates at 192V nominal — matching the internal battery bus of the Smart-UPS RT extended-runtime platform. This is not a universal battery pack; it is voltage-matched to the RT series, which means no voltage conversion losses and straightforward integration with the host UPS battery management circuit.
- 3U Rack Form Factor: At 3 rack units tall, the SURT192RMXLBP fits standard 19-inch equipment racks and pairs cleanly with rack-mounted Smart-UPS RT units. If your rack layout is tight, account for the 3U before ordering — extended-runtime configurations often pair one or more of these packs with the base UPS, so total rack consumption adds up.
- Extended Runtime Purpose: The core reason to add this pack is runtime extension. The base Smart-UPS RT ships with an internal battery; this external pack supplements that capacity, which translates directly to more minutes of protected runtime at a given load. Actual runtime depends on the connected load and the host UPS model — verify the runtime curves for your specific UPS and load before sizing.
- Black Rack-Ready Finish: The black enclosure matches standard rack aesthetics and is consistent with the Smart-UPS RT chassis color, keeping mixed-equipment racks visually clean and making the battery pack easy to identify in documentation and photos.
- EAR99 Export Classification: Classified EAR99 under U.S. export regulations — no export license is required for most destinations, simplifying procurement for multinational projects or installations at international sites.
- California Prop 65 Compliance Noted: The product carries a California Proposition 65 warning for cancer and reproductive harm — standard for lead-acid battery products. Factor this into site documentation and disposal planning, particularly for installations in California or organizations with environmental compliance requirements.
Integration & Compatibility
The SURT192RMXLBP is designed for the UPS battery expansion ecosystem of the Smart-UPS RT series. The "SURT" prefix in the model number indicates compatibility with the RT extended-runtime platform. Before purchasing, confirm that your specific Smart-UPS RT model explicitly supports this battery pack — APC publishes compatibility tables by UPS model number. Pairing the wrong battery pack with a UPS can result in battery management errors or charging failures, so cross-reference the host UPS documentation. For power protection planning in rack environments, consult the runtime extension tables published by APC for the host UPS to determine how many packs are needed to meet your target runtime at your actual load. If you are building out a network equipment rack or security head-end and need to calculate total UPS and battery capacity, the combination of host UPS watt rating and this pack's added capacity determines your runtime budget. A UPS sizing guide can help you work through load calculations before committing to a configuration.
Frequently Asked Questions
Q: Which UPS models is the SURT192RMXLBP compatible with?
A: The SURT192RMXLBP is designed for the APC Smart-UPS RT extended-runtime series (SURT-prefix models). Confirm compatibility with your specific host UPS model number using APC's published compatibility tables before purchasing — not all Smart-UPS RT models accept every battery pack variant.
Q: What battery chemistry does the SURT192RMXLBP use?
A: It uses a sealed lead-acid battery at 192V nominal. Lead-acid chemistry is standard for this class of UPS battery extension pack and is supported by the Smart-UPS RT battery management system.
Q: How many rack units does the SURT192RMXLBP require?
A: The SURT192RMXLBP occupies 3U (three rack units) in a standard 19-inch rack. Plan your rack layout accordingly, especially if you intend to install multiple packs for additional runtime extension.
Q: Does the SURT192RMXLBP require a separate power connection?
A: The battery pack connects to the host Smart-UPS RT via the dedicated battery expansion interface — it does not require a separate AC power feed. The host UPS manages charging. Refer to the APC user manual for cable routing and connector details specific to your UPS model.
Q: Is the SURT192RMXLBP subject to any export restrictions?
A: No — the SURT192RMXLBP is classified EAR99, meaning no U.S. export license is required for most destinations. Standard shipping and export documentation applies.
When I spec out runtime extension for Smart-UPS RT deployments, the SURT192RMXLBP is the pack to reach for when you need to add battery capacity inside the rack rather than rolling in a separate floor-standing battery cabinet. The 192V bus voltage is specific to the RT extended-runtime architecture — that voltage match is what allows the host UPS to manage charging and discharge across the combined internal and external battery strings without additional hardware.
Technical Highlights:
- 192V Nominal Voltage: Matched to the Smart-UPS RT internal battery bus — no step-up or conversion circuitry required, which keeps efficiency high and simplifies battery management.
- 3U Rack Footprint: Three rack units is the space cost for meaningful runtime extension. In a fully loaded 42U rack, that is a 7% space commitment — reasonable for a head-end closet where runtime during a grid event can mean the difference between a clean shutdown and a hard crash.
- Lead-Acid Chemistry: Sealed lead-acid is proven, field-serviceable, and well-understood by facilities teams. Battery replacement at end-of-life follows standard lead-acid disposal procedures, which most commercial facilities already have in place.
Deployment Considerations:
- Verify your specific Smart-UPS RT model number against APC's battery pack compatibility table before ordering — the SURT prefix family spans multiple wattage tiers, and not every RT model accepts every pack variant.
- California Prop 65 applies to this product due to lead-acid chemistry — factor that into site documentation, local compliance requirements, and end-of-life battery disposal planning.
This pack fits best in security operations centers, telecom closets, and network head-ends where the host Smart-UPS RT is already installed and the goal is adding 15–45 minutes of additional runtime to outlast typical utility disturbances or buy time for a managed shutdown of NVRs, access control servers, and switching infrastructure.
