APC by Schneider Electric SRT96RMBPUS Smart-UPS SRT 96V Rackmount Battery Pack
Overview
The SRT96RMBPUS is a dedicated 96V rackmount battery expansion pack designed for the APC Smart-UPS SRT 3kVA platform. When a single internal battery string isn't enough runtime for your critical load — whether that's network closet infrastructure, edge surveillance recording, or server room equipment that needs to ride through extended outages — this unit extends your UPS runtime without adding a second UPS to the stack. It drops into a standard 19-inch rack and pairs directly with compatible Smart-UPS SRT 3kVA units, giving you a deterministic, manufacturer-designed runtime extension rather than a field-fabricated workaround.
For integrators sizing power protection for security or IT infrastructure, this approach keeps the battery architecture clean: one UPS brain, one or more battery packs, one management interface. That's simpler to monitor, simpler to service, and simpler to document for the end customer.
Key Features
- 96V rackmount battery architecture: Matched voltage to the SRT 3kVA UPS string means no voltage mismatch, no derating — the UPS sees a compatible battery pack and extends runtime predictably. Correct voltage pairing is the difference between a supported configuration and a voided warranty.
- Rack-optimized physical footprint: At 17.01 inches high, 5.12 inches wide, and 26.88 inches deep, this unit is sized for standard 19-inch rack bays. The 26.88-inch depth is the spec to verify against your rack's usable depth before ordering — shallow two-post racks or short four-post enclosures may not accommodate it without a shelf extension.
- RBC152 battery replacement path: When the cells reach end-of-life, the RBC152 Battery Kit (also available in PowerSWAP format) is the correct field-replaceable unit. PowerSWAP packaging is designed for hot-swap replacement without removing the entire pack from the rack — a practical advantage in live environments where downtime windows are tight.
- Purpose-built for Smart-UPS SRT 3kVA systems: This is not a generic battery cabinet. It is engineered and validated for the SRT platform, which means compatibility with the UPS's battery management circuitry, runtime calculation engine, and remote monitoring via the UPS's existing network management card.
Integration & Compatibility
The SRT96RMBPUS is designed for use with APC by Schneider Electric Smart-UPS SRT 3kVA rackmount UPS systems. Before deploying, confirm your UPS model explicitly supports this battery pack — consult the Smart-UPS SRT compatibility matrix. Multiple battery packs can typically be chained to further extend runtime; verify the maximum pack count supported by your specific UPS model to avoid overloading the charging circuit.
For environments running network video recorders, access control servers, or communications infrastructure, pairing this battery pack with a correctly sized uninterruptible power supply is the standard approach to meeting uptime SLAs during utility outages. Rack integration also benefits from a power distribution unit downstream to manage individual circuit loads cleanly.
Frequently Asked Questions
Q: What UPS systems is the SRT96RMBPUS compatible with?
A: The SRT96RMBPUS is designed for the APC Smart-UPS SRT 3kVA rackmount platform. Verify your specific UPS model number against APC's compatibility documentation before ordering to confirm supported configurations.
Q: What is the correct replacement battery for the SRT96RMBPUS?
A: The RBC152 Battery Kit is the designated replacement. It is also available in PowerSWAP format, which supports replacement without fully removing the pack from the rack.
Q: Will the SRT96RMBPUS fit in a standard 19-inch rack?
A: The unit is 17.01 inches high and 5.12 inches wide, designed for 19-inch rack mounting. The depth is 26.88 inches — verify your rack's usable depth accommodates this before installation.
Q: Can multiple SRT96RMBPUS packs be connected to a single UPS for additional runtime?
A: The Smart-UPS SRT platform is designed to support external battery packs for extended runtime. The maximum number of packs supported depends on your specific UPS model — check the UPS documentation for the supported battery pack count to avoid overloading the charger.
Q: Is the SRT96RMBPUS a standalone UPS or a battery expansion only?
A: It is a battery expansion pack only — it does not contain an inverter or transfer switch. It requires a compatible Smart-UPS SRT 3kVA UPS to function.
The SRT96RMBPUS is a straightforward runtime extension decision — if your Smart-UPS SRT 3kVA needs more battery capacity and you're in a standard rack environment, this is the manufacturer-designed path. The 26.88-inch depth is the one spec that catches integrators off guard, so measure your rack usable depth before the unit ships.
Technical Highlights:
- 96V matched voltage: Pairs to the SRT 3kVA battery string without voltage adaptation — no derating, no compatibility asterisks when the UPS calculates available runtime.
- RBC152 / PowerSWAP replacement: PowerSWAP format means end-of-life battery swap can happen in-rack without a full unit removal — reduces maintenance window time in live telecom closets or server rooms where pulling the pack offline is disruptive.
- 17.01 × 5.12 × 26.88 in form factor: Standard 19-inch rack width, but the nearly 27-inch depth means this won't fit shallow two-post open-frame racks without a shelf. Plan rack depth at the design stage, not on delivery day.
Deployment Considerations:
- Confirm your UPS model explicitly supports the SRT96RMBPUS and verify the maximum number of external packs the charger can handle — exceeding that count risks undercharging all packs in the string.
- This unit has no standalone function — without a compatible Smart-UPS SRT 3kVA host, it is inert. Don't spec it as a replacement for the UPS itself in a budget-reduction conversation.
Best fit for security operations centers, network closets, or surveillance recording infrastructure where a Smart-UPS SRT 3kVA is already installed and runtime extension is the only gap — not for new installations that haven't yet selected a UPS platform.
