APC by Schneider Electric SRT72RMBP Rackmount Extended Runtime Battery Pack
Overview
The APC by Schneider Electric SRT72RMBP is a 2U rackmount battery pack engineered to extend the runtime of compatible Smart-UPS SRT 2.2kVA systems. For data closets, edge network racks, and security infrastructure where a brief battery window is not enough, adding the SRT72RMBP gives you a measured increase in ride-through time without replacing or upgrading the base UPS unit. The black 2U chassis fits standard 19-inch rack enclosures — no external footprint, no floor-standing battery cabinet required.
Battery type is lead-acid — a proven chemistry for UPS applications that delivers predictable discharge curves and broad compatibility with APC's Smart-UPS SRT charge management. The unit ships at 17 inches in depth, so verify available rack depth before ordering, particularly in shallow telecom or wall-mount enclosures.
Key Features
- 2U Rackmount Form Factor: integrates directly into a standard 19-inch rack alongside the host UPS — no shelf, no floor space, no separate enclosure needed. Keeps your power infrastructure consolidated and cable runs short.
- Lead-Acid Battery Chemistry: delivers a well-understood, stable discharge profile suited to the controlled-temperature environment of a server room or IDF closet. Replacement batteries are widely available, which matters when you're planning a multi-year support lifecycle.
- Extended Runtime Design: the SRT72RMBP adds battery capacity beyond what the base SRT unit carries internally — relevant when your load includes network switches, NVRs, access control panels, or other gear that cannot tolerate even a brief outage during a utility event.
- Compatible with Smart-UPS SRT 2.2kVA: designed specifically for the SRT platform's modular battery architecture, so the host UPS recognizes the pack, manages charging, and reports accurate runtime estimates through its management interface.
- Black Rack Finish: matches standard rack aesthetics in mixed-vendor environments. Minor detail, but consistent with professional installation standards in visible or client-facing equipment rooms.
- EAR99 Export Classification: no export license required for most destinations — simplifies procurement for multi-site or international deployments subject to US export administration rules.
Integration & Compatibility
The SRT72RMBP is designed for the APC Smart-UPS SRT series modular battery ecosystem. Before ordering, confirm that your specific SRT host unit lists this battery pack as a compatible extended runtime module — APC publishes compatibility matrices on their support portal. This pack does not function as a standalone UPS; it requires a compatible host UPS to operate. For full APC by Schneider Electric UPS and power protection products, review the complete lineup. If you are building out a rack for surveillance or access control infrastructure, pair this with an appropriately sized PoE network switch and budget your UPS load accordingly — cameras, NVRs, and door controllers add up faster than most initial estimates account for.

Frequently Asked Questions
Q: What UPS models is the SRT72RMBP compatible with?
A: The SRT72RMBP is designed for APC Smart-UPS SRT 2.2kVA systems. Verify compatibility with your specific host model number using APC's official compatibility documentation before purchasing.
Q: Is the SRT72RMBP a standalone UPS?
A: No. The SRT72RMBP is a battery extension pack only. It requires a compatible APC Smart-UPS SRT host unit to charge, manage, and discharge the batteries. It provides no UPS functionality on its own.
Q: What battery chemistry does the SRT72RMBP use?
A: Lead-acid. This is the standard chemistry for the Smart-UPS SRT platform, offering predictable runtime and a straightforward replacement cycle when batteries age out.
Q: How much rack space does the SRT72RMBP require?
A: The SRT72RMBP occupies 2U in a standard 19-inch rack. Verify available rack depth as well — the unit is 17 inches deep per published dimensions.
Q: Does the SRT72RMBP require an export license?
A: No. The SRT72RMBP carries an EAR99 ECCN classification, which means no export license is required for most international destinations under US Export Administration Regulations.
The SRT72RMBP comes up regularly when integrators are sizing power for security closets that run 24/7 — NVRs, managed PoE switches, access control hardware. The 2U lead-acid pack extends the runtime window of the Smart-UPS SRT 2.2kVA host, which is often the difference between a graceful shutdown with recorded footage intact and a hard cutoff mid-incident. It's a straightforward add-on, but it has to be matched to the right host unit or you're just buying a box of batteries with no management interface.
Technical Highlights:
- 2U Rack Integration: fits directly in the same rack as your UPS host — no supplemental enclosure, no floor-standing cabinet. Keeps the power stack organized in tight IDF or security equipment rooms.
- Lead-Acid Chemistry: well-understood discharge behavior under the cyclic load patterns typical of security infrastructure. Replacement cells are straightforward to source, which matters on a 3–5 year battery lifecycle.
- EAR99 Classification: no export license required for most destinations — useful when procurement involves multi-site or international facilities under a single purchase order.
Deployment Considerations:
- The SRT72RMBP only functions paired with a compatible Smart-UPS SRT 2.2kVA host. Confirm the host model's compatibility list before the PO is cut — not every SRT variant lists this pack as a supported module.
- Rack depth is 17 inches: measure your cabinet's usable depth before ordering. Short-depth wall-mount enclosures common in smaller access control closets may not accommodate this unit without modifications.
Best fit for mid-size security or network equipment rooms where the base UPS runtime is insufficient for the load profile — specifically mixed NVR, switch, and access control deployments where 15–20 additional minutes of runtime can mean the difference between a clean failover and data loss.
