Review: Network card included makes this a great value - We have 11 remote locations and all have at least one server 2 Cicso POE switches and other equipment. We use APC Infrastruxure Manager and needed a good value UPS that would allow monitoring via IM. This is it. Love the display ( our existing APC UPS' did not have one) , though menu navigation can be a challenge first couple of times through ( of course the web interface is the best way). Also, you don't have to own a IM appliance & software to monitor, you can do it via the web interface. So, do your runtime needs calculations and if this has your power requirement met you are good to to go. By the way, I have ordered 14 since January. Each of my sites gets two for redundantly. Some of the older UPS' just got new batteries. Speaking of batteries - ordered 33 from desertcart, but beware many have a 5 per 7 days ordering restriction. That is a pain. Review: DOA; did not include network card - Item arrived with bent rack ears (minor issue), no network card (description states with network card) and not functioning - the UPS states the battery is at 100% but when entering self-test, it reports "self-test refused". On connecting to a server load, this is reported as 10% load and a nice long run time is estimated (I think about 30 mins). However if line power is disconnected, the UPS shuts down within 10 seconds - it only has one real job and it fails. Still waiting for the vendor to get back to me. desertcart originally offered a partial refund which wasn't a satisfactory option ## Features - Extended-run battery systems provide flexible runtime to critical Smart-UPS applications - External Battery Pack for use with specific APC SMX model UPS This external battery pack does not funcation on its own, but must be used with an SMX model UPS - Compatible with the following APC SMX models of UPS: SMX2000RMLV2U, SMX2000RMLV2UNC, SMX2200RMLV2U, SMX3000RMLV2U, SMX3000RMLV2UNC - Multiple battery pack configuration: connect up to 10 battery packs for extended runtime applications - Includes: Installation guide, Rack Mounting brackets ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007TL5QFM | | Batteries | 2 Product Specific batteries required. | | Best Sellers Rank | #360 in Computer Uninterruptible Power Supply Units | | Customer Reviews | 3.6 3.6 out of 5 stars (70) | | Date First Available | January 1, 2011 | | Department | APC Smart-UPS X 120V External Battery Pack Rack/To | | Is Discontinued By Manufacturer | No | | Item Weight | 124.3 pounds | | Item model number | SMX120RMBP2U | | Language | English | | Manufacturer | APC | | Product Dimensions | 26.26 x 17.01 x 3.35 inches | ## Product Details - **Battery Cell Composition:** Sealed Lead Acid - **Brand:** APC - **Color:** Black - **Material:** Plastic - **Voltage:** 120 Volts ## Images ![External Battery Pack for Smart-UPS Extended Run SMX-Series, SMX120RMBP2U, 120V, 2U Rackmount/Tower Convertible, Black - Image 1](https://m.media-amazon.com/images/I/51395hiaOZL.jpg) ![External Battery Pack for Smart-UPS Extended Run SMX-Series, SMX120RMBP2U, 120V, 2U Rackmount/Tower Convertible, Black - Image 2](https://m.media-amazon.com/images/I/618K-5PBF-L.jpg) ![External Battery Pack for Smart-UPS Extended Run SMX-Series, SMX120RMBP2U, 120V, 2U Rackmount/Tower Convertible, Black - Image 3](https://m.media-amazon.com/images/I/61e5e3qqyGL.jpg) ![External Battery Pack for Smart-UPS Extended Run SMX-Series, SMX120RMBP2U, 120V, 2U Rackmount/Tower Convertible, Black - Image 4](https://m.media-amazon.com/images/I/61lS4NuG9JL.jpg) ## Questions & Answers **Q: Which UPS models are compatible with SMX120RMBP2U?** A: Smart-UPS X extended runtime models above 2kVA are compatible with SMX120RMBP2U. **Q: How many external battery packs can be added to a Smart-UPS X?** A: You can combine up to 10 external battery packs to Smart-UPS X for extended runtime. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Network card included makes this a great value *by Z***Y on June 9, 2013* We have 11 remote locations and all have at least one server 2 Cicso POE switches and other equipment.

Mounting the rails takes a bit of time, but other than that setup was simple. Make sure to remove the battery before placing the case in the rack: it makes the case only about 25 lbs versus almost 100 lbs with the battery. Big improvement in this model: no longer has screws to anchor the battery in the case. Everything is toolless now (minus install). Also, the display shows all kinds of good information: watt draw, amp draw, % usage, runtime, etc. Hopefully it stands the test of time! ## Frequently Bought Together - APC External Battery Pack for Smart-UPS Extended Run SMX-Series, SMX120RMBP2U, 120V, 2U Rackmount/Tower Convertible - APC UPS Network Management Card 3 with 2 USB ports and Temperature Monitoring, Newest Model 2020 (AP9641) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/20473133-external-battery-pack-for-smart-ups-extended-run-smx-series](https://www.desertcart.com.pa/products/20473133-external-battery-pack-for-smart-ups-extended-run-smx-series) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-05*
