here is something puzzling to me. On CyberPower's site, they list the CP1350AVRLCD3 as running for 14/4min on half/full load. but they have the CP1500AVRLCD3 running for 12/3min on half/full load. why would that be? could it be a misprint?

The two units use the same battery. So, a unit with a higher allowable VA rating will have a shorter runtime. The 9AH battery is the limiting factor.
My APC commercial 1500VA UPS uses four 12V 9AH batteries. Still 1500VA but four times the battery reserve. You can't use the VA rating to judge a UPS.

ah I see. so why would someone spend more on the 1500 model if the battery won't last as long as the 1350 model?

If they have a load (VA) greater than the 1350 will support, it may just error and not support at all. But the 1500, might carry it for a short time.
This all goes back to my statement in post # 17. You HAVE to measure you actual usage. You are just guessing about everything without actual power measurements.

ok I understand.

I know, i'm just trying to understand how it works right now. i'm reading from others that have more things plugged into theirs and the battery is lasting very long. i might just buy the 1350 model and see how long the battery lasts. if its not long enough, I can return it to amazon. I don't want to spend another $60 on the electricity usage monitor.

Here is a QNAP how to -- https://docs.qnap.com/operating-system/qts/5.0.x/en-us/configuring-the-ups-settings-2AD2FE5E.html
You put a USB cable between the port at the top of the UPS and your NAS. Then you configure the UPS monitor software on the NAS. When the UPS battery gets low it will automatically shut down the NAS. I wouldn't worry about network gear.

how do you put the UPS software on the nas? I can't find the software in the available applications to download on the nas and the Cyber Power site only shows this application available for windows, mac or linux.

Update: it takes almost 24 minutes to shutdown my nas. About 20 minutes just to stop Virtualization Station with a VM still running. I suspect it would be quicker if i first shutdown the VM then shutdown the nas, but i wanted to see how long it would take in a case where the power goes out during the night or when i’m not home.
 
It's not a misprint. This is what confuses many people. Both models use the SAME two batteries inside. The 1500VA version can just handle more load, which means the batteries wouldn't last as long at half of that load. If you put the same load on the 1500VA unit as you put on the 1350 (not a half load, but the same load on both units) then they would both probably last the same amount of time.

Your actual runtime is probably only going to be measured when you have the unit in hand, plugged in, and testing it.

edit - my bad, for some reason my browser didnt show the 2nd page right away...

I know this now. I plan on getting the CP1350AVRLCD3 today.

Is it ok to try it by unplugging the ups from the wall?
Click to expand...
That is exactly how I test my many UPS if it has been a number of months since I lost power. Most UPS will give a very clear warning when the battery gets so low the UPS is going to turn off. You can then quickly just plug it back into the wall. Better to have issue when you can just plug it back in and order new batteries that it to happen when you have no idea how long the power is going to be out.

The batteries in a UPS will provide less and less time as they get older. It seems to degrade even when they in effect were not used.

What you don't want is the batteries to get so bad that the power fails and the UPS shuts down withing seconds. From my experience it seems you start to see significantly less time after about 3 years.
 
Ok I tested it and the nas shutdown automatically. But I had it set to turn on automatically when the power came back on. The setting I used is “last state”. The last state of the nas was on, so it should have turned on but it didn’t. I had to turn it on manually.
 
It all depends on how "smart" the nas is. It might have though its final state was "off" since it turned itself off before the power from the UPS expired. If you were to just cut the power it might be in a "on" state but that kinda defeats your whole purpose for the UPS. So maybe try to let the nas shut it self off and then uplug it to simulate the UPS completely draining the battery.

Not sure about a nas but I have used this method to remote start a pc. I set the bios option to boot on power restore. I then use a shutdown command and then turn off one of those fancy power plugs. When I turn the fancy power plug back on the pc boots.

Possibly you want 'Turn on NAS automatically'

When the power goes out, what is the difference between
  1. Turn off the server after the AC power fails
  2. The system will enter “auto-protection” mode after the AC power fails
