APC by Schneider Electric SRYLRMXBP Modular Ultra External Battery Pack
Overview
The APC by Schneider Electric SRYLRMXBP is a rackmount external battery pack designed specifically for the Smart-UPS Modular Ultra platform. Pre-fitted with four Lithium-Ion battery modules delivering 4.94 Ah of capacity, it adds runtime extension to your Smart-UPS Modular Ultra installation without requiring a separate battery enclosure. The 1U-compatible rack form factor (440 mm wide × 130 mm high × 740 mm deep) integrates into standard 19-inch cabinets alongside the parent UPS, keeping your power infrastructure consolidated and accessible. For data centers, network closets, and critical-load deployments that need predictable extended runtime from a proven modular UPS family, the SRYLRMXBP is the purpose-built solution.
Key Features
- Lithium-Ion Chemistry (4.94 Ah, 4 Modules): Li-Ion cells carry a significantly longer service life and hold charge more efficiently than VRLA alternatives — meaningful when you are managing a high-density rack environment where scheduled battery replacements are disruptive and costly. Four discrete modules also mean you can track each module's health independently rather than guessing across a monolithic battery block.
- Wide Operating Temperature — 0 to 50 °C: Standard VRLA UPS batteries derate or fail early above 25 °C. The SRYLRMXBP's 0–50 °C operating window keeps it viable in warm equipment rooms and industrial environments where ambient temperatures regularly exceed data-center norms — without forced derating of capacity.
- Storage Temperature Range — -20 to 60 °C: If you warehouse spare packs or ship to sites with extreme ambient conditions (cold climates, unheated storage), the -20 °C floor means the cells arrive ready for service without a conditioning cycle. The 60 °C ceiling similarly accommodates warm-side warehouse or shipping container staging.
- Rackmount Form Factor (440 × 130 × 740 mm): 130 mm height translates to approximately 3U, a compact footprint for the runtime it delivers. The 440 mm width fits standard EIA-310 19-inch rack rails without adapter kits. At 740 mm depth, verify your cabinet's usable depth — shallow-depth wall-mount racks may require a depth extension bracket.
- Operating Altitude — 0 to 3,000 m: Deployments at elevation (mountain data centers, high-altitude industrial sites) often run into UPS derating flags. The 3,000 m ceiling covers the vast majority of real-world installations without altitude-based derating, reducing commissioning headaches at remote or elevated sites.
- Non-Operating Altitude — 0 to 15,000 m: Safe for air freight to any commercial destination without special packaging waivers — the cells tolerate full commercial cargo-hold altitude during transit, simplifying international logistics for global deployments.
- REACh and RoHS Certification: Both certifications confirm the battery pack meets EU chemical substance restrictions — required for import into the European Economic Area and increasingly expected by enterprise procurement teams as a baseline environmental compliance requirement, regardless of deployment geography.
Integration and Compatibility
The SRYLRMXBP is engineered as an external battery expansion unit for the Smart-UPS Modular Ultra product line. Confirm compatibility with your specific Smart-UPS Modular Ultra model before ordering — APC's modular UPS platforms use discrete battery interfaces, and not all external battery packs are cross-compatible across the full Smart-UPS lineup. Connection is handled through the dedicated battery port on the parent UPS chassis; no additional power distribution unit or bypass switch is required for the battery extension function itself. Management of the battery pack — including charge status, health, and runtime estimates — is surfaced through the parent UPS's management interface, keeping monitoring consolidated in a single pane.
Frequently Asked Questions
Q: What battery technology does the SRYLRMXBP use, and how does it compare to lead-acid alternatives?
A: The SRYLRMXBP uses Lithium-Ion (Li-Ion) cells. Li-Ion chemistry offers a longer cycle life and operates efficiently across a wider temperature range (0–50 °C operating) compared to standard VRLA lead-acid batteries, which typically derate above 25 °C and have shorter replacement intervals.
Q: What is the total battery capacity of the SRYLRMXBP?
A: The SRYLRMXBP ships with four battery modules providing a combined capacity of 4.94 Ah. This figure reflects the total deliverable capacity across all four included Li-Ion modules.
Q: What are the physical dimensions, and will it fit a standard 19-inch rack?
A: The unit measures 440 mm wide × 130 mm high × 740 mm deep. The 440 mm width is designed for standard 19-inch EIA-310 rack rails. Verify your cabinet's usable depth of at least 740 mm before installation — shallow-depth wall-mount enclosures may not accommodate this unit without a depth extension.
Q: Is the SRYLRMXBP suitable for high-altitude installations?
A: Yes. The SRYLRMXBP is rated for operating altitudes up to 3,000 m, which covers the large majority of commercial and industrial deployment sites. For non-operating transport, it is rated to 15,000 m, making it safe for standard commercial air freight without special packaging waivers.
Q: What compliance certifications does the SRYLRMXBP carry?
A: The SRYLRMXBP is certified REACh and RoHS compliant, confirming it meets EU regulations on restricted chemical substances. This is a baseline requirement for deployments within the European Economic Area and is increasingly expected by enterprise procurement standards globally.
Q: Can the SRYLRMXBP be used as a standalone UPS or with any UPS brand?
A: No. The SRYLRMXBP is an external battery expansion pack designed specifically for the APC Smart-UPS Modular Ultra platform. It is not a standalone UPS and is not compatible with other UPS brands or unrelated APC product lines. Always confirm compatibility with your specific Smart-UPS Modular Ultra model before ordering.
The SRYLRMXBP is the runtime-extension answer for Smart-UPS Modular Ultra installations where the base runtime is insufficient for the load profile — particularly in consolidation racks running high-density compute or surveillance NVR stacks that need to ride out 15–30 minute outages cleanly. The Li-Ion chemistry here is not a checkbox; the 0–50 °C operating ceiling means this pack holds its rated 4.94 Ah in equipment rooms that would cause a VRLA pack to derate significantly before the load even hits it.
Technical Highlights:
- Li-Ion at 4.94 Ah across 4 modules: Modular construction lets you replace individual cells as they age rather than swapping a monolithic block — reduces battery maintenance downtime in live rack environments.
- 0–50 °C operating range: Covers warm-aisle equipment rooms and industrial edge closets where ambient can exceed 35–40 °C — conditions that cut VRLA service life in half but fall within this unit's design envelope.
- REACh + RoHS certified: Both certifications are required for EU import; for enterprise buyers running global procurement standards, this avoids a compliance re-review cycle that can delay deployment by weeks.
Deployment Considerations:
- At 740 mm deep, measure your rack's usable interior depth before ordering — many 4-post open-frame racks are fine, but compact 2-post or wall-mount enclosures frequently fall short of this depth requirement.
- The SRYLRMXBP is not a universal battery pack — it is platform-specific to Smart-UPS Modular Ultra. Deploying it with a non-compatible UPS chassis will result in a non-functional installation; confirm your parent UPS model number against APC's compatibility matrix before purchasing.
This pack is the right call for a data center or network operations center running Smart-UPS Modular Ultra as primary power protection, where rack space is constrained but runtime requirements exceed what the base UPS unit alone can deliver — particularly in environments above 30 °C ambient where Li-Ion's thermal tolerance directly translates to reliable runtime during an actual outage.
