I had a split second surge in my building and two of my APCs failed even though
when i looked at it in the morning it said was still FULLY charged to the top.
Some of my servers and switches went down. when i press the test button.
It beeps and all my equipment loses power and then comes back up.
then failes again after serveral minutes then comes back up again..
While the ups is plugged into the wall. why does it still lose power if im plugged in to the wall power?
The battery has been replaced not long ago.
can a split second surge/spike cause the battery to fail?
isnt this what the ups suppose to protect?
It seems like the indictaors on the front are not accurate at all.
should the batteries be replaced every year? half year?
how often to switch out the ups?
any rule of thumb?
