situation is that, my own 2kva UPS doesn't even last 5mins anymore, so I went and bought new batteries
installed them and then I decided to try and use a multimeter to maybe check status of the old batteries
now I notice that some of the batteries read 12V+ and then some read 10+ and 2 or 3 reads below 10
(this was "supposedly" when UPS read that the batteries were 100% charged)
now my question is: isn't that 12V+ still actually good or does over charge mean bad?
then, if the above is actually good, what else could then cause the UPS to not stay on? some other component damaged?
any1 that can give some more info regarding my current UPS maintenance?
