APC by Schneider Electric SURT192XLBP Extended Runtime Battery Pack
Overview
The SURT192XLBP is a 3U rack-mount extended runtime battery pack designed for use with APC Smart-UPS RT (SURT) series uninterruptible power supplies. If your facility runs mission-critical loads — surveillance recorders, network infrastructure, access control servers — and standard runtime isn't enough to outlast an extended outage or safely execute a controlled shutdown, this battery pack is how you bridge that gap without swapping out the UPS itself. It uses a sealed lead-acid battery chemistry in a black, rack-integrated 3U chassis (17 inches deep), sized to stack directly below or above compatible SURT-series units in a standard 19-inch rack enclosure. The SURT192XLBP pairs with the host UPS to extend runtime proportionally — the more packs you add (where the UPS supports it), the longer your protected equipment stays online during a power event.
This is not a standalone UPS — it is a dedicated external battery module that requires a compatible APC Smart-UPS RT host unit. Verify your specific SURT model supports external battery packs before ordering; not all SURT configurations accept XL battery expansion.
Key Features
- 3U Rack Form Factor: At 3 rack units tall and 17 inches deep, the SURT192XLBP integrates into standard 19-inch equipment racks without requiring a separate enclosure or floor-standing footprint. This matters in dense IDF closets or co-located rack rows where floor space is a premium — you keep the runtime extension in-rack, cable-managed, and physically secured alongside the UPS host.
- Sealed Lead-Acid Chemistry: Lead-acid battery technology is proven, predictable, and widely serviceable. Unlike lithium chemistries, lead-acid cells don't require specialized disposal chains in most jurisdictions and have well-understood charge/discharge curves that UPS management software can model accurately for runtime estimates. Expect periodic battery replacement (typically every 3–5 years depending on operating conditions and cycle count) as part of planned maintenance.
- Black Rack Finish: The black chassis matches standard APC Smart-UPS RT aesthetics in mixed rack environments — a minor but practical detail when rack presentation matters in customer-facing data closets or NOC environments.
- EAR99 Export Classification: The SURT192XLBP carries an EAR99 designation, meaning it does not require an export license for most destinations under U.S. Export Administration Regulations. For integrators managing multi-site deployments that include international locations, this simplifies procurement and shipping logistics.
- Extended Runtime on Demand: Rather than oversizing your base UPS to hit a runtime target, you add this pack to an existing SURT host — a more cost-efficient approach when your load profile is already well-matched to the UPS capacity but you need more minutes during an outage. For surveillance environments, additional runtime can mean the difference between a camera system that captures the full duration of an incident versus one that goes dark mid-event.
- California Prop 65 Notice: The product carries a Prop 65 warning for cancer and reproductive harm, which is standard for lead-acid battery products sold or shipped into California. Factor this into site documentation and disposal planning for CA-based deployments.
Integration & Compatibility
The SURT192XLBP is engineered for the APC by Schneider Electric Smart-UPS RT product family — specifically the SURT-series models that support external XL battery expansion. Before specifying this pack, cross-reference your host UPS model number against APC's published compatibility list to confirm it accepts the SURT192XLBP. The 192V battery string voltage must match what the host UPS expects from an external pack; mismatched voltage configurations are not supported and will not function.
For integrators building out rack-mount UPS solutions for security and surveillance infrastructure, the SURT192XLBP fits naturally into deployments where an NVR, PoE switch, and access control server share a common UPS — and where a single power event long enough to exhaust base runtime is an unacceptable risk. Pair the host SURT UPS with a compatible rack enclosure to house both the UPS and this battery extension in a secure, organized installation. Consult a power protection planning guide to size runtime requirements against your load before ordering. For broader power protection options across the catalog, review the full APC battery pack lineup.
Frequently Asked Questions
Q: Is the SURT192XLBP a standalone UPS or does it require a host unit?
A: It is not a standalone UPS. The SURT192XLBP is an external battery pack that must be connected to a compatible APC Smart-UPS RT (SURT-series) host unit to function. It provides no power conversion or load protection on its own.
Q: What battery chemistry does the SURT192XLBP use?
A: Sealed lead-acid. This is the same chemistry used in the host APC Smart-UPS RT units. It is maintenance-free under normal conditions but will require periodic replacement, typically every 3–5 years depending on operating environment and cycle history.
Q: How many rack units does the SURT192XLBP occupy?
A: Three rack units (3U). It is designed to mount in a standard 19-inch rack enclosure alongside the host SURT UPS.
Q: Can I stack multiple SURT192XLBP packs to extend runtime further?
A: Whether multiple external battery packs can be daisy-chained depends on the specific host SURT UPS model. Check the host unit's documentation for the maximum number of supported external battery packs.
Q: Does the SURT192XLBP ship to California?
A: Yes, but it carries a California Proposition 65 warning for cancer and reproductive harm, which is standard for lead-acid battery products. Ensure your facility's battery disposal procedures comply with local regulations.
Q: What is the export classification of the SURT192XLBP?
A: EAR99 — no export license is required for most international destinations under U.S. Export Administration Regulations.
The SURT192XLBP is a 3U sealed lead-acid battery extension module for the APC Smart-UPS RT family — the spec that matters most here is not glamorous, but it is critical: this pack occupies exactly 3U in your rack and runs at 192V, which means your host SURT model must explicitly support external battery expansion at that voltage string. I have seen integrators spec the wrong XL pack for their SURT host and end up with a non-functional installation, so verify the host compatibility before the purchase order goes out.
Technical Highlights:
- 3U Rack Integration: Fits a standard 19-inch rack, stacks adjacent to the host SURT unit — no separate cabinet, no floor footprint, no additional rack hardware beyond what comes with the pack.
- Sealed Lead-Acid Chemistry: Predictable degradation curves mean your UPS management software (PowerChute or equivalent) can give accurate runtime estimates throughout the battery lifecycle — not just when the cells are new.
- EAR99 Classification: No export license required for the vast majority of destinations, which matters for multi-site security deployments that span international locations and need streamlined procurement.
Deployment Considerations:
- Confirm your host SURT UPS model explicitly supports the SURT192XLBP before ordering — not every Smart-UPS RT variant accepts XL battery expansion, and the 192V string voltage is specific to the SURT platform.
- Lead-acid cells degrade faster in high-ambient-temperature environments (above 25°C/77°F accelerates aging meaningfully); if your rack runs hot, factor shortened replacement cycles into the total cost of ownership.
For a surveillance or access control head-end rack where the NVR, core switch, and door controller all share a single SURT host UPS and standard runtime falls short during extended utility outages — this is the direct solution, provided the host model supports XL expansion.
