I found the UPS with fans running when I came home today. Then I noticed it was saying 75% battery left in my computer which the UPS is connected to. When there is a power outage on my house, I can tell it by my microwave's clock resetting. Which was not the case. So I have no idea why UPS went below 100% when there's no outage. Anyway that's the least of my problems.
It has been 9 hours since I'm home, and it's still charging. It shows 98% battery at the moment. And the fan noise is really driving me crazy. The room temperature is 20 Celcius/ 68 Fahrenheit, and UPS is not hot or anything to touch. I had a budget Powercom UPS before which didn't make a peep unless it was running on battery power.
So 1.) Is it normal that it has been 9 hours between 75% and 97% battery capacity and it's still charging? and 2.) Is there any way to reduce...
