APC by Schneider Electric SYAXR9B9 Symmetra LX Extended Run Battery Cabinet
The SYAXR9B9 is a dedicated extended runtime battery enclosure for the Symmetra LX UPS family, housing nine factory-installed SYBT5 lead-acid battery modules in a free-standing tower cabinet. If your critical load — server room, communications closet, or security operations infrastructure — demands runtime beyond what the base UPS provides, this is the add-on enclosure that delivers it without rack-space penalties. At 769.63 lb (349.1 kg) fully loaded, this is a floor-standing installation with no rack-mount option, so plan your space and structural loading accordingly before the unit ships.
Overview
The SYAXR9B9 pairs directly with the Symmetra LX UPS platform as a dedicated extended runtime module. Unlike generic battery cabinets, it ships with all nine SYBT5 battery modules pre-installed and zero empty slots — the cabinet is fully populated from day one, meaning you are deploying full runtime capacity immediately without a staged battery-fill process. The single interconnect cable routes directly to the Symmetra LX base unit, keeping wiring straightforward in environments where cable management is a concern.
The enclosure is designed for indoor, climate-controlled spaces. An operating altitude range of 0–10,000 ft and a relative humidity tolerance of 0–95% (non-condensing) means it handles most data center, IT closet, and security operations center deployments without derating concerns. Storage tolerances extend to 15,000 ft altitude and temperatures from 5°F to 113°F (−15°C to 45°C), which matters when the unit is warehoused or staged before installation in a controlled room.
Key Features
- Nine Pre-Installed SYBT5 Battery Modules: All nine battery slots are occupied at shipment — zero empty slots means zero staged-expansion delay. You deploy at full runtime capacity on day one rather than purchasing and installing modules incrementally.
- Lead-Acid Battery Chemistry: VRLA (valve-regulated lead-acid) technology provides predictable discharge curves and a well-understood replacement cycle. The SYBT5 is a widely stocked, standard-format module — replacement sourcing is straightforward compared to proprietary lithium chemistries.
- 120V Battery Voltage at 208V Input: The cabinet operates at 208V input — confirm your facility's power feed before scheduling installation. This is a common voltage in purpose-built data center environments and larger IT rooms, but not universal in general commercial construction.
- Free-Standing Tower Form Factor: The enclosed battery cabinet mounts on the floor, not in a rack. At 23.70 inches in one dimension and 769.63 lb loaded, it requires dedicated floor space and a structural floor assessment. This is not a decision to make after the unit arrives on-site.
- CSA Certified, UL 1778 Listed: UL 1778 is the North American standard for uninterruptible power supplies — carrying this listing satisfies the baseline safety compliance requirement for most commercial and enterprise facilities. CSA certification extends coverage to Canadian installations.
- 0–10,000 ft Operating Altitude: No derating required at altitudes up to 10,000 ft — relevant for deployments in Denver, Mexico City, and similar high-altitude locations where battery performance can degrade on lesser-rated equipment.
- 0–95% Relative Humidity Tolerance: The cabinet tolerates a wide humidity range, which provides margin in spaces that aren't tightly climate-controlled — though lead-acid batteries still perform best in stable, cool environments.
- Single Cable Interconnect: One cable connects the SYAXR9B9 to the host Symmetra LX UPS. Simpler wiring means faster installation and fewer failure points in the power path.
Integration & Compatibility
The SYAXR9B9 is purpose-built for the Symmetra LX UPS platform. Verify your specific Symmetra LX model supports an external extended runtime enclosure and that the 208V input matches your facility's power infrastructure. The replacement battery for this cabinet is the SYBT5 — document this SKU for your facilities team before initial deployment so battery replacement cycles can be planned and budgeted correctly. The cabinet ships in black finish; mounting mode is floor-standing only (not rack-mountable), so standard rack-mount data center deployments will need to allocate adjacent floor space.
Frequently Asked Questions
Q: Is the SYAXR9B9 fully populated with battery modules at shipment, or do I need to purchase modules separately?
A: The SYAXR9B9 ships with all nine SYBT5 lead-acid battery modules pre-installed. Battery slots empty is zero — there is nothing additional to purchase for full runtime capacity.
Q: What is the replacement battery module for the SYAXR9B9?
A: The replacement battery for this cabinet is the APC SYBT5. There are nine modules per cabinet. Document this SKU for your maintenance and facilities team so battery replacement cycles can be planned and procured in advance.
Q: Can the SYAXR9B9 be rack-mounted?
A: No. The SYAXR9B9 is not rack-mountable. It is a free-standing, enclosed floor tower cabinet. At 769.63 lb (349.1 kg) fully loaded, a structural floor load assessment is required before installation.
Q: What input voltage does the SYAXR9B9 require?
A: The SYAXR9B9 operates at 208V input. Confirm that your facility's power feed is 208V before scheduling delivery and installation. This voltage is standard in purpose-built data center environments but may not be present in general commercial construction without additional panel work.
Q: What certifications does the SYAXR9B9 carry?
A: The SYAXR9B9 is CSA certified and UL 1778 listed. UL 1778 is the North American standard for uninterruptible power supplies, satisfying the baseline safety compliance requirement for most commercial and enterprise deployments. CSA certification covers Canadian installations.
Q: What UPS platform is the SYAXR9B9 compatible with?
A: The SYAXR9B9 is designed for use with the APC Symmetra LX UPS family as a dedicated extended runtime enclosure. Verify your specific Symmetra LX model supports an external battery cabinet before purchasing.
The SYAXR9B9 is one of those units that looks straightforward on paper but demands pre-installation discipline in the field. Nine SYBT5 lead-acid modules at full load brings the cabinet to 769.63 lb — that is not a number you discover after it clears the freight dock. Floor loading, positioning, and the 208V power feed all need to be confirmed before the unit ships, not after.
Technical Highlights:
- Nine SYBT5 Modules Pre-Installed: Full runtime capacity from day one, with zero empty slots to fill later. Each SYBT5 is a standard-format module, well-stocked through normal supply channels — no exotic procurement process when replacement cycles come due.
- UL 1778 / CSA Listed: These listings satisfy North American safety compliance requirements for commercial UPS deployments and are specifically required by many facilities management standards and insurance carriers — not an optional credential on a unit of this class.
- 0–10,000 ft Operating Altitude: No derating required at altitude, which matters for high-elevation data center and security operations deployments where lesser-rated battery cabinets lose effective capacity.
Deployment Considerations:
- This is a floor-standing-only cabinet — not rack-mountable. Build your floor plan around it before finalizing the room layout; repositioning a 769 lb cabinet after the fact is a facilities project, not a quick adjustment.
- The 208V input requirement is non-negotiable. Verify the panel feed before scheduling installation; 120V facilities will need electrical work that should be scoped and budgeted as part of the project, not discovered on install day.
The SYAXR9B9 is the right choice for a Symmetra LX deployment in a purpose-built data center or security operations center where extended runtime is a hard requirement and floor space has been properly allocated — not a drop-in for a general commercial IT closet without advance coordination with facilities.
