this one.. APC rack mount 1500VA sinewave

https://www.amazon.com/APC-Smart-UPS-Battery-Rack-Mount-SMC1500-2U/dp/B007ZT2KV6

and man it weighs like a ton.

had it 4 years now no issues. prolly due for new batteries but it passes all self tests.

Just beware. I have an APC of a similar size. Probably not quite as nice but last time I replaced the batteries, it still said it had plenty left but couldn't sustain my server when I pulled the plug.

I have just replace 3 x APC UPS 1500 (Tower) today.. Same issue!.. Little power trip and the entire server shuts down and the UPS reboots... If you are brave, pull the mains power!

Either the UPS will kick over to run on battery OR turn off completely.

If it is stays on, you may notice it drains the battery very quickly.... from 100% to 20% in less than 30secs...

Another thing I noticed was, once you connect the AC the UPS will reboot/re-initialize, causing your equipment to either power cycle or stay off.

The toughest part of the day was lugging 6 x 22AH SLA batteries up the stairs to the comms rack/room. Despite the challenges, these are great UPS units, and it's worth noting that these 3 were still going strong after nine years with their original batteries!

i have 3 of those APC 1500VA sinewave jobs (one rack stype and 2 box type that sit on the floor and look ugly (so says my wife), one in the rack (main network, freenas box and NVR) , one on the HTPC and associated audio gear and one of the daily driver computer. the "unplug it" test works on them all but i didnt time them, i just pull it for maybe 30 seconds with about 1/2 load.

but yeah new batteries for all of them is on the list as theyre all 4ish years old.. just been lazy as they are way overpowered for the load i have them hooked to.

anything worth doing is worth overdoing i figure.

I've overloaded these as well, I really didn't expect to use these UPS for anything else but the following...

1. Stay running for the occasional brownout.. Little flicker off and on.
2. approx. 5min of runtime during a blackout, then power off all servers if power isn't restored.
3. Filter AC power for Pure Sinewave (Hardware longevity)
4. Surge protection

It is a pain to work with them.. they are heavy and awkward because the are small with no handles... Pulling them out of a data rack is no easy task. So I did put this off for a few months. But today I was mentally prepared!

I sometime do laugh when clients think they are meant to keep their server running for hours and hours, like a generator. I told them these are just entry level UPS for the above and if you want something that will run for hours, expect to be paying 50-100x more and build me a new server room to house it!

I have one more at another clients place, 5 years old and same issue... I also replaced another 2 in December 2022...

I have more than 50 of these units scattered all around. So it is a never ending job replacing batteries!
