@kaia My storage/media server and compute HA cluster runs on a Dell-branded APC Smart-UPS. I use it so power cuts don't result in data loss, and also for power filtering.
@kaia I've used APC both at home and at work. Mostly due to reasonable Linux support via apcupsd
My UPSes are getting quite old now, so I would need to do a new evaluation next time. I can still get replacement batteries for the ones I have, so I'm not in a rush. Might use this list as a kind of guide ... https://networkupstools.org/stable-hcl.html
@kaia from a professional who works in this area, anything Cyberpower, APC, or Eaton is ok. Make sure you get it from authorized retailer so your warranty is valid they’ll cover battery failure like 5 or 7 years. Eaton owns Cyberpower so they’re two sides of the same coin.
I’d get one with USB integration you can plug it into the computer and with apcupsd you can have it push the shutdown button on its own if battery gets to 10% or so for a clean shutdown. It also shows up in Linux like a laptop battery with the charge level in the tray if you want.
@kaia Yes, with a laptop battery. But I've worked with APC, Cyberpower and Eaton batteries. Cyberpower and Eaton are fine (Eaton is pricier), but APC is very hit or miss depending on the model (batteries fail, inverters explode). The nickname A Piece of Crap exists for a reason.
Currently using CyberPower. Got it on Amazon. Reasonably priced. Works well. I also have my Internet router on one so I don’t have to wait for a reboot on the case of a quick blink.
@kaia Several of my clients go through UPSes regularly. While I encourage them to just get batteries, they still sometimes replace them outright, and I take all the old ones.
The most common, of course, are APC. They’re also the most pricey when new. Some of the smaller ones are built to take smaller than standard 7.2 to 9VA batteries, but easily removable plastic in the case is all that’s taking up the additional space which, of course, I remove, so most of the UPSes all get the same batteries.
CyberPower UPSes are good, but sometimes they come with mediocre batteries, and people incorrectly assume the issue is the hardware when it’s the batteries.
I can’t think of any that are actually bad, but I’d say if you’re considering getting one or two, see about getting a used one and buying new batteries from a reputable seller with good ratings.
Most can be used with apcupsd, even when they’re not APC brand.
So now most of my friends and family have a UPS on their Internet / phone in their homes, thanks to recycling and new batteries :)
