APC Smart-UPS On-Line SRT Battery Pack for 3kVA Extended runtime model 96V

Product Overview

AI-generated summary

If you’re running an APC Smart‑UPS On‑Line SRT 3kVA and you actually care about “keep going when the grid doesn’t,” this battery pack is a sensible extension. The value is mainly in avoiding downtime: the SRT series is designed so you can add runtime in a controlled, supported way, rather than cobbling together generic battery solutions. At £1181.05 ex‑VAT, it’s not cheap, but for a UK business it’s often cheaper than the cost of a short outage to a key server, comms gear, or storage system—especially if you’ve already got the base UPS installed and you’re just trying to buy more minutes.

That said, I wouldn’t buy it unless your current setup is already compatible and you’ve confirmed you’re targeting longer runtime for a real reason. Battery packs like this are only “worth it” if you need the extra hold‑up time—otherwise you’re paying for capacity you’ll never use. Also factor in that batteries age and eventually need replacing, so you’re committing to future maintenance planning. If you’re unsure, I’d check your UPS model, expected load, and current runtime first—if you don’t have a clear runtime gap to close, the money is better spent on reducing load, upgrading power management, or simply ensuring the existing UPS is performing as it should.
