APC Smart-UPS SRT Extension Cable for External Battery Packs 5/6kVA UPS, 192VDC, 15ft

Product Overview

AI-generated summary

Honestly, this is one of those “sounds boring but matters” accessories. If you’ve already got an APC Smart-UPS SRT system and you’re extending with compatible external battery packs, this extension lead is the right way to do it—clean integration, proper fit, and less faff than improvising with anything non-APC. In that scenario, £338.78 ex‑VAT is painful but not outrageous, because the alternative is either downtime/inefficiency from incorrect cabling or paying for labour to make a fragile setup that won’t be supported.

I wouldn’t buy this if you’re just trying to get “extra reach” for a UPS placement that isn’t well planned—measure first, and make sure your battery pack model and the UPS voltage pairing match the SRT ecosystem. If you don’t specifically need external battery pack extension, it’s expensive empty length. For UK businesses running small datacentres/office comms rooms where the battery cabinets need siting away from the UPS, it’s a sensible, low-risk purchase; for everyone else, it’s a cost you’ll feel every time you look at the invoice.
