I hold a master's degree in electrical engineering specializing in electronics; a simulated sine-wave is more than sufficient for 99% of today's home electronics. Power supplies are designed to support a varying range of voltage inputs, allowing a single supply to be used across most of the world. Therefore, they can easily account for subtle variations in voltages from a simulated wave.

I would be shocked to see a Sony device fail because it ran on a simulated sine wave or to have a warranty denied because of it, unless they specifically state not to use one.

This are good overviews:

https://www.lifewire.com/modified...ion-534760
I'm curious if you just unplugged the TV from the simulated battery backup device and hid the battery backup device in the other room if they would have honored the warranty?
FWIW, I have the earlier version of this UPS, GX1325U, and was able to get replacement batteries for $14+SH & tax...

Quote from CyanFaucet7364 :
I guess YMMV with the quality of these. I've owned 3 and every single one has had a problem esp when the batteries start to die. In my main unit which powers my main PC, monitors, etc. after maybe 2 years, I was getting an E21 error which indicates a battery output short. I replaced them with brand new Cyberpower batteries, and same error so the power board likely died and I had to toss the entire thing. In my unit downstairs which powers my NAS, I also had to replace the batteries on those when it start beeping every time there was a surge and it could not hold any charge on the battery backup. After replacing those, the power button LED and display completely fails to turn on so looks like it took out something else in the process, but functionally it seems to be working. A replacement unit I got once to RMA a DOA unit died altogether after about a year (looks like they sent a refurb, it was not new).

I'm sure there are many success stories, but I haven't had any good luck with these. When they do work, they're fine, but batteries will ultimately die and many times it will take something else out with it. In all three cases, it was this very same UPS, the 1500VA 900W. Do yourself a favor and pay a bit more to get something more enterprise grade from a company like Tripp Lite. I'd probably even vouch for APC pure sine wave over these at this point.

Cyberpower generally has a 3yr warranty for their UPS devices. But sounds like you threw one out after it failed in 2 years?

I misspoke. Checked my order history on that unit and I bought it from Amazon on 7/28/20. So yes I threw it out thereafter as they wouldn't cover it after that period was up.

The other one whose display and LEDs are completely gone I purchased from Staples on 7/14/21 and since it seems to still function, I rather not waste my time with a replacement. Like I said, I did get another 1500VA for use at my local church that was completely DOA and they had sent me a refurb back that did not last.

I'm just speaking from my own experiences and will avoid Cyberpower in the future. I'm sure many others are using these just fine. When they work, they work fine.

Quote from thatswhatshesaid :
Have this unit for 8yrs, just replaced the batteries for $50. The problem is not with the unit but getting one that is new. A month ago I bought this and had it shipped to home, box very damaged and unit was obviously a return. I had a second one shipped to the store and the same thing. I dont have "expensive" electronics. The only issue I've ever noticed is when I ran the garage door opener, it ran but sounded odd when running. I read that the simulated sine wave affects motorized devices.
That is the down side to Costco's excellent return policy. The returns just get resold.

Its best to get the real thing. The pure sine do go on sale at Costco. Had one last year. Best to wait it out imo.

If yours was shipped without an additional box it was just damaged in route. Many complaints about this. I ordered one before and it came double boxed. At shippers whim. And they be shipped direct from Cyber P if I recall correctly.

The QC on these is awful. One connector wasn't even tight enough to power the unit on. The other is missing a part of the insulation...

I once had a very old non sine wave version CP1000AVRLCD looked like this: https://www.officedepot.com/a/pro...-9-Outlet/
Once and after running for a little more than 5 years one day I came back home seeing the device is stuck in blank display and non-stoppable beep sound while there are no record of power outage, all connected devices lost power while the outlet itself is working fine.
It is a disaster as I have to recover some corrupted data and a few critical devices took days and weeks to be restored to its original state.
I guess it is partly on me given the fact I'm not replacing the battery every once in a while however I do believe it is manufacturer's responsibility to ensure the device operate properly even in case of the battery failure or not holding a charge.
I no longer buy CyberPower UPS ever since.

This sounds like what happens because the CyperPower units put the batteries in series with the AC current and so, by design, the AC power cuts out when the batteries fail. You are right that checking the condition of the batteries regularly would avoid this type of situation. The alternative with an APC-type set-up is that the power does not go out when the batteries fail, but the APC unit could fail you in an actual power outage unless you've been checking the condition of the batteries regularly in that unit, as well.

Tetro hydo cannibanoid. It helps you transition from stable power to sleepy power.

I wish a manufacturer would sell a 'batteryless' UPS unit that allows you to connect whatever 12v lead acid battery you want. I want to have a car battery bank.

Quote from Mastercylinder :
Whats interresting is my same unit has no problem running my router, modem, surveillance, PC, or monitor, plugged into it. However it will not run or recharge off my generator. THC is most likely the issue, yet everything else in my house runs fine on the generators power.
Your generator; like many, makes dirty power that is so bad the UPS does not recognize it. I've had a similar experience, the noise of the generator is just too high; you need a line conditioner or a better quality generator (better electronics.)
