I’m running a rather small homelab and am hunting for a good UPS to help keep everything running smoothly. My top priorities are:
- Just enough battery life to keep things running until they can be shut down
- Compatible with open source software for monitoring and automated shutdown
Would I have better luck getting a used one and a new battery, or a brand new unit altogether? Anyone have one they don’t need anymore, on that note? 👀
Thanks for the advice!
The problem is when you do, instead of their units continuing to power your devices via power from the wall, they shut off power to all their battery ports. So CyberPower battery units can and will cause outages for your devices without you even having a power outage event. It’s a critical design flaw their competitors don’t share.
Haven’t had this happen. Battery pack failed after 10 years. Unit still provided mains AC through battery backup plugs. There is a switcher inside to flip between mains and battery…maybe that was going bad in what you describe.
I’ve never seen a CyberPower not cut power to its battery ports when the battery failed, which I’ve seen dozens of times since the failure rate on them was bordering on the absurd. When contacting CyberPower to warranty them, they told us that was normal and that the units were designed that way.
I guess in my case the batteries may have had enough to signal they were functional, but they were effectively dead and had no UPS backup sustaining power. One battery had started to buldge its container. I can see it as being an as designed feature, that way they never let you down in a powerfailure event, as you get advanced notice that the battery is no longer working LOL. Had a corporation go down a few years ago, they had not replaced UPS batteries, when power wentout all UPS batteries were dead and couldn’t sustain the servers until backup generator came online.
