What exactly do you think a UPS is for?  They are designed to run for 
several minutes during a moderate power outage, and then inform the 
machines to cleanly shut down before the battery goes critical.  Under 
full load on fresh batteries, you likely won't get much more than about 
10 minutes out of one.  If you are looking for *hours* of operation 
running one or more Myth boxes and their attached TVs, you need to 
invest in a generator.

If on the other hand you were asking about keeping your network online 
during an extended outage so you can continue to use the internet on 
your laptop, you're woefully off topic.
