Re: [Nut-upsuser] System with MGE UPS shuts down too early

Yes it could be problem with some of the cells. I consider going to the service, but I do not have another backup UPS and the service requires leaving the UPS for at least 3 days (I presume, so they could perform such tests). I'll try replacing the batteries and if it doesn't help, then I'll go

Re: [Nut-upsuser] System with MGE UPS shuts down too early

Hello Manuel, that looks perfectly fine That one yes, but as I wrote, LB and FSD are happening on much higher battery charge values - 90% or more, which is not fine. That's... surprisingly well, assuming your multimeter indicates correct values. I would have expected values well below 12V

Re: [Nut-upsuser] System with MGE UPS shuts down too early

Hello. I sometimes encountered batteries that were ok, but at times one of the cells would develop a random short/open, therefore reducing the real capacity even if voltage reading was ok. In the absence of a battery load tester i would suggest running multiple tests with a load (car headlight bul

OK, so yesterday evening I done a real test cutting of the power to the UPS. And it went good... the UPS supported my server for 28:50 minutes (i.e. the expected runtime with this load), before forcing shutdown. The batteries could still hold as charge was 30 % with about 15 minutes run time. A

Re: [Nut-upsuser] System with MGE UPS shuts down too early

OK, my UPS turned out to be older that I thought. I apparently bought and installed it in September 2016 (not 2017 as I initially wrote). That makes for over 3 years of work, which is over the life expectancy of the batteries, so I ordered new battery pack. However, how could I make a full cha
