installed locally for computer backup in some local city and
company offices - about 30 total.
Of those, about 1/2 had batteries good enough to even fire up
the UPS, and about 1/2 of those that did were very marginal,
such as only having enough capacity for 10 minutes instead of
the rated 30 minutes or so.
Going by that, I would bet that nearly half of the UPS systems
in the country don't work.
Back a few years ago when I was doing this kind of thing for a |
living the group I was working with had standardized on APC UPSs
for several reasons. One was the on-board self testing that could
be scheduled on a periodic basis where the system would actually
switch to battery and measure how long it took to consume 10% of
it's charge, and report that to the computer monitoring all the
UPSs. Made it handy to check the battery status, etc.
