Re-reading I was thinking the same thing. Batteries don't just "die", they degrade in performance.
How did he also know power didn't go out too? That confused me as well.
- monoideism 6y agoProbably he knew because none of his other electrical appliances were reset.
- danilocesar 6y agobecause he gets emails from the unit when it happens. I had a script in a raspberry pooling my UPS each minute asking if the unit was running on AC or battery, and dropping that info into a file when it changed. I know the software/daemon can also do something like that.
- jaywalk 6y agoYes, but in this case he wouldn't have gotten an email since the UPS failed right when the power went out. I actually had the exact same thing happen to me a few months ago. A power flicker so brief that it didn't even reset any of my clocks, but it caused one of my cheapo standby UPSes to give out.
