I have a CyberPower 600VA UPS and it has died within 12 months.
I use it as a backup for my NBN NTD which has the smallest power draw. (~8W I believe) However, I was woken up the other night to the thing screaming from my garage with a constant alarm, not like the regular beeping, but the buzzer was a constant blaring sound with no intermittence.
Unplugged it and plugged back in, same thing.
Before I go out and try buying a new battery, has anyone had any experience with these? Are they just terrible products as a whole, or is it just the batteries they ship with?
If it's the latter does anyone have any recommendations on a good replacement?
I haven't had a single issue with my 2 x Powershield Defender 1200's for my server and Router/Switch/Cameras…
Cheers,
Spoods
Have had no problem with mine, just as good as the Eaton ones I usually get.
You don't know how long the unit you have has been in storage so it may have had a dud battery when you purchased it, try a new one and see how you go. I usually get CSB batteries from eBay.
If you wanted to test whether your UPS is fried, swap one of your batteries from your Powershield to test
