APC Smart-ups Ultra Battery Pack 48V - UXABP48

APC by Schneider Electric UXABP48 48V External Battery Cabinet

Overview

The UXABP48 is a 48V lead-acid external battery cabinet designed to extend runtime for compatible APC Smart-UPS Ultra systems. Weighing in at 280.58 lb (127.27 kg) and finished in black, this is a floor-standing, non-rack-mountable unit built for environments where extended backup duration is a hard requirement — think critical infrastructure closets, edge data rooms, and security operations centers where a brief outage isn't just inconvenient, it's a failure. If your runtime math doesn't add up with the internal battery alone, the UXABP48 is the expansion answer for APC by Schneider Electric Smart-UPS Ultra deployments.

Key Features

• 48V Lead-Acid Battery Chemistry: Lead-acid at 48V delivers the high energy density needed to back sustained loads on Smart-UPS Ultra systems. This is proven, field-serviceable chemistry — not a proprietary cell format that locks you into a single supplier for replacements years down the line. For power backup and UPS deployments, that serviceability matters when the battery cycle count eventually runs out.
• 280.58 lb / 127.27 kg Operational Weight: At over a quarter-ton fully loaded, placement planning is non-negotiable. This unit does not go in a rack — it is a floor-standing cabinet. Confirm your floor load rating before delivery, particularly in raised-floor environments where point-load limits can be surprisingly low.
• Non-Rack-Mountable Form Factor: The floor-standing design keeps the battery mass off your rack infrastructure entirely, which matters in environments where rack-weight budgets are already constrained by dense compute or switching gear. Position it adjacent to the UPS host, not in the rack column.
• Black Cabinet Finish: The black finish integrates cleanly into standard server room and security operations center aesthetics without requiring custom housing or shrouding. A minor point, but one less thing to address on a formal facilities walkthrough.
• Package Dimensions (17.01 × 32.99 × 20.00 in / 43.2 × 83.8 × 50.8 cm): The shipping carton runs 314.67 lb (142.73 kg) — 34 lb heavier than the unit itself. Plan your receiving dock and unboxing crew accordingly. A pallet jack rated for at least 350 lb is the minimum; a two-person lift to remove the cabinet from packaging is expected. Verify doorway and corridor clearances against the 32.99-inch package width before the truck arrives.
• External Runtime Extension Architecture: Adding an external battery cabinet rather than over-sizing the UPS itself gives you runtime flexibility without replacing capital equipment. When your load profile grows or runtime requirements change, you add capacity incrementally — a more cost-effective approach than a full UPS swap for network infrastructure and security head-end rooms.

Integration and Compatibility

The UXABP48 is designed for use with APC Smart-UPS Ultra systems that support 48V external battery expansion. Before ordering, verify your specific Smart-UPS Ultra model's compatibility with this battery cabinet — not every unit in the Smart-UPS Ultra line accepts an external pack, and connector and communication compatibility must be confirmed against your host UPS model number. Consult the power protection accessories category for compatible cabling and connectivity components. For sizing guidance on runtime requirements across multiple connected devices, reference a UPS selection guide to confirm this cabinet delivers the additional amp-hour capacity your load demands.

Installation requires a stable, level floor surface capable of supporting the 280.58 lb operating weight at the intended footprint. The unit ships fully assembled as a cabinet; internal battery configuration is pre-set at 48V. No rack ears, no vertical mounting — floor placement only.

Frequently Asked Questions

Q: Is the UXABP48 rack-mountable?

A: No. The UXABP48 is a floor-standing battery cabinet and is not designed for rack installation. It must be placed on a level floor surface capable of supporting its 280.58 lb (127.27 kg) operating weight.

Q: What battery voltage does the UXABP48 provide?

A: The UXABP48 operates at 48V using lead-acid battery chemistry, designed to match the external battery expansion input of compatible APC Smart-UPS Ultra systems.

Q: How heavy is the UXABP48 when it ships?

A: The shipping package weighs 314.67 lb (142.73 kg). The unit itself weighs 280.58 lb (127.27 kg). Plan your receiving dock, lift equipment, and installation crew for a load exceeding 300 lb.

Q: What are the shipping dimensions for the UXABP48?

A: The shipping carton measures 17.01 in H × 32.99 in W × 20.00 in D (43.2 × 83.8 × 50.8 cm). Verify doorway and corridor clearances before delivery.

Q: Can the UXABP48 be used with any UPS, or only specific APC Smart-UPS Ultra models?

A: The UXABP48 is intended for compatible APC Smart-UPS Ultra systems. Compatibility is model-specific — verify your host UPS model supports 48V external battery expansion before ordering.

Q: What type of batteries are inside the UXABP48?

A: The UXABP48 uses lead-acid batteries at 48V. Lead-acid chemistry is well-established in UPS applications and supports field serviceability and replacement over the cabinet's service life.

Jerry Tildsen

The UXABP48 is a runtime extension play, not a standalone UPS — and that distinction matters before you spec it. At 280.58 lb and a non-rack form factor, it demands floor real estate and load-bearing confirmation that a lot of integrators skip until the delivery truck shows up. Get the floor rating and the doorway measurement done before you PO this unit.

Technical Highlights:

• 48V Lead-Acid Chemistry: Proven UPS chemistry at 48V — field-replaceable cells, no proprietary battery modules, long supply chain tail for replacements when the original cells reach end of service life.
• 280.58 lb Operating Weight: That mass is the tradeoff for high amp-hour capacity. A pallet jack and two-person installation crew is the minimum — single-person install is a safety non-starter at this weight class.
• 314.67 lb Shipping Weight: The 34 lb delta between shipped and operational means packaging materials are substantial. Unboxing logistics in a finished server room or narrow corridor require a plan — this is not a roll-it-in-and-cut-the-shrink-wrap job.

Deployment Considerations:

• Confirm floor load rating at the intended installation point before delivery — particularly in raised-floor environments where the point load from a 280 lb cabinet can exceed tile weight ratings, requiring spreader plates or repositioning to a structural support grid.
• The UXABP48 is compatibility-specific to APC Smart-UPS Ultra systems that accept 48V external battery expansion. Do not assume cross-compatibility with other Smart-UPS product lines — verify against your exact host UPS model number before ordering.

This cabinet is the right call for security operations centers, edge infrastructure closets, and camera head-end rooms where the host Smart-UPS Ultra's internal runtime falls short of the outage window you're designing against — and where replacing the UPS entirely would be a larger capital event than adding battery capacity alongside it.
