APC by Schneider Electric SYBT5FR Symmetra LX Flame Retardant Battery Module
Overview
The SYBT5FR is APC's flame retardant battery module designed for the Symmetra LX uninterruptible power supply family. Where standard battery modules are acceptable in general data center environments, the SYBT5FR addresses stricter fire-code and insurance requirements with flame retardant construction — a meaningful distinction in facilities where battery compartment fire risk is a compliance or underwriting concern. The module carries both CSA and UL 1778 certifications, confirming it has passed North American safety standards for UPS battery systems before it ever reaches your equipment room.
At 32.3 kg, this is a dense, rack-integrated component. Plan for two-person installation and verify your rack's weight capacity before committing to a battery bay configuration in the Symmetra LX chassis.
Key Features
- Flame Retardant Construction: The defining characteristic of the SYBT5FR over standard Symmetra LX battery modules. Facilities subject to stricter fire codes, insurance mandates, or internal safety policies that require flame retardant battery enclosures can deploy this module where a standard module would not satisfy the requirement. If your data center or IDF room has specific material-class requirements for battery housings, this is the module to specify.
- CSA and UL 1778 Certification: Both CSA and UL 1778 listings mean this module has been independently tested to North American UPS battery safety standards. UL 1778 specifically governs uninterruptible power supplies, so procurement teams and AHJs (Authorities Having Jurisdiction) can verify compliance without custom testing. This matters at commissioning time and during periodic safety inspections.
- Operating Temperature Range 0–40°C: The 0–40°C operating window is standard for commercial UPS battery modules and covers the full range of conditioned equipment room environments. This is not a wide-temperature or extended-range module — if your battery room or IDF closet runs warm or lacks climate control, verify the room stays consistently below 40°C, as elevated operating temperatures accelerate battery degradation and reduce effective capacity over time.
- Storage Temperature Range -15–45°C: The -15–45°C storage envelope gives reasonable flexibility for pre-deployment staging — a module waiting on a loading dock or in an unconditioned warehouse in moderate climates will stay within spec. Avoid freezing temperatures during long-term storage, as battery chemistry is sensitive below -15°C.
- Operating Humidity 0–95% (Non-Condensing): The 0–95% relative humidity rating means the SYBT5FR handles the humidity range found in virtually any conditioned equipment room. This is not an outdoor or harsh-environment rating — condensing moisture must be avoided. Standard equipment room humidity controls (40–60% RH) keep this module well within its operating window.
- Storage Humidity 0–95%: Matches the operating humidity range, simplifying staging logistics. As with operating conditions, condensing humidity should be prevented during storage to avoid corrosion on battery terminals and connectors.
- Operating Altitude 0–3000 m: The 3000-meter altitude ceiling covers virtually all commercial building deployments in North America and most of the world. High-altitude data centers (Denver at ~1609m, for example) fall well within spec. Only facilities above approximately 10,000 feet need to evaluate derating or alternative equipment.
- Package Weight 32.3 kg (approximately 71.2 lbs): At over 71 lbs, this module requires proper lift-assist equipment or two-person installation. Rack bay positioning should account for weight distribution across the Symmetra LX chassis — consult APC's installation documentation for recommended battery bay loading sequence to avoid chassis imbalance during partial population.
Integration and Compatibility
The SYBT5FR is designed specifically for the APC Symmetra LX UPS family. Before ordering, confirm compatibility with your specific Symmetra LX frame model and firmware revision via APC's compatibility documentation. The Symmetra LX is a modular, scalable UPS architecture — battery module bay count, hot-swap capability, and runtime scaling depend on the specific frame configuration. This module's flame retardant designation makes it a direct substitute for standard Symmetra LX battery modules in facilities where that construction requirement applies; verify your frame's battery bay type accepts the SYBT5FR form factor before procurement.
For large-scale deployments across multiple Symmetra LX frames, the Power & UPS category includes compatible Symmetra LX components including additional battery modules, intelligence modules, and frame units. Pairing with APC's full APC product line allows consistent sourcing across the Symmetra LX ecosystem. For facilities planning UPS infrastructure alongside broader network infrastructure buildouts, battery runtime planning should account for total connected load including switching, compute, and storage equipment. Consult a UPS sizing and runtime guide to match battery module count to your runtime target at full and partial load. Rack and power accessories including PDUs and cable management should be specced concurrently with battery module count to avoid layout conflicts in the Symmetra LX bay.
Frequently Asked Questions
Q: What makes the SYBT5FR different from a standard Symmetra LX battery module?
A: The SYBT5FR uses flame retardant materials in its construction, making it suitable for facilities where fire codes, insurance requirements, or internal safety policies mandate flame retardant battery housings. Standard Symmetra LX battery modules may not satisfy those requirements.
Q: What certifications does the SYBT5FR carry?
A: The SYBT5FR is certified to CSA and UL 1778 standards, covering North American safety requirements for uninterruptible power supply battery systems.
Q: What is the operating temperature range for the SYBT5FR?
A: The SYBT5FR operates between 0°C and 40°C. It should not be used in environments that exceed 40°C, as sustained elevated temperatures will accelerate battery wear and reduce runtime capacity.
Q: How much does the SYBT5FR weigh?
A: The packaged weight is 32.3 kg (approximately 71.2 lbs). Two-person installation or mechanical lift assistance is recommended. Verify your rack's weight capacity and consult APC's recommended bay loading sequence before installation.
Q: Can the SYBT5FR be used at high-altitude facilities?
A: Yes. The SYBT5FR is rated for operation from 0 to 3000 meters above sea level, covering the vast majority of commercial facility deployments worldwide, including high-altitude locations such as Denver.
Q: What humidity levels does the SYBT5FR tolerate?
A: The SYBT5FR operates and stores within 0–95% relative humidity. Condensing moisture must be avoided. Standard equipment room humidity control (40–60% RH) keeps the module well within its rated envelope.
The SYBT5FR comes up most often when a facility's fire marshal or insurer has flagged battery enclosure material class as a compliance item — the flame retardant construction is the single spec that separates this module from the standard Symmetra LX battery option. In practice, if you're not operating under that specific requirement, the standard module is the default; but when the requirement exists, the SYBT5FR is the only APC-native answer for the Symmetra LX platform that satisfies it without workarounds. Worth noting upfront for any procurement or design review conversation involving this SKU.
Technical Highlights:
- UL 1778 + CSA Dual Listing: Both marks present means this module clears the bar for the vast majority of North American AHJ and insurance reviews without supplemental testing — reduces commissioning friction on compliance-sensitive projects.
- 0–40°C Operating Range: Tight upper bound compared to some industrial battery solutions. Conditioned equipment rooms stay well within range, but any IDF or wiring closet without active cooling that can spike above 40°C during summer or high-load periods is a real risk to battery service life — not just a spec footnote.
- 32.3 kg Package Weight: At ~71 lbs, rack-level weight planning is non-negotiable. In a fully populated Symmetra LX chassis with multiple battery bays, cumulative weight can challenge standard two-post and some four-post rack ratings — verify the rack's floor-loading and rail weight spec before finalizing bay count.
Deployment Considerations:
- Confirm the specific Symmetra LX frame model accepts the SYBT5FR form factor before procurement — the Symmetra LX family spans multiple frame generations and bay configurations, and not all frames accept all module variants interchangeably.
- The 0–95% humidity rating includes a non-condensing constraint that is easy to overlook during cold-weather delivery and staging. A module brought in from a cold truck into a warm equipment room can see condensation on terminals — allow adequate acclimation time before installation.
The SYBT5FR is the right specification for Symmetra LX deployments in healthcare facilities, financial data centers, and government installations where battery enclosure fire retardancy is a documented compliance requirement — not a general-purpose upgrade over the standard module for environments where that requirement doesn't apply.
