Howdy,
*Follow Up*
As promised I did a "Live" test by unplugging UPS from line power to see if the batteries would perform as expected.
NUT has been disabled before running this test.
Results, SME ran for 47 minutes on battery without a hitch. At this point the UPS was reconnected to line power.
Any of my past experiences with this UPS have given me between 45-50 minutes of run time. This will remove the new but faulty battery from my equation.
So let me respond to some of the helpful comments so we can continue forward.
@reetp "You could have a look at installing apcupsd, at least for testing "
Yea, thats not an option this is my production server. The only version of apcupsd available for CentOS 6 base is a third party package. Also,
the How-Tos on contribs.org are very, very outdated. This would pollute the testng environment IMHO. My expectations are that NUT may be capable of working with this APC unit in stock form.
@mmccarn "There is some chance that the calculation for "battery.runtime" factors in the apparent age (19 years)"
Interesting, is there documentation that shows how or where we can set battery date??
When I looked through the NUT docs, there wasn't any mention that the date was used with any of the calculations. It appeared to be a reference line?
My thinking is, the NUT config needs to be told how many minutes the UPS can run, 45 minutes which would be about 2700 seconds, however the SME config for nut doesn't appear to have an option for setting the battery.runtime?
Again, thanks for helping.
