Since we're talking UPSes, I think I have a APC Smart-UPS  
1000VA  ..or atleast it looks like the one on the APC site.

I found it stashed in a corner of the unit that I now use for  
my shop. All it needed was a new battery for operation.

That was over 8 years ago now.

It can provide close to 2 hours for the DSL modem, switch,  
debit/credit card terminal and the cash register.

Since the batt is pretty old, maybe I should time it  
unplugged.  I expected it to operate longer than it did in the  
recent storm we had here that knocked everything out for 24  
hours.

I also have a APC Smart 750 for my main shop pc. It was in  
Hibernate and scheduled to bootup at 6:30a.  It didn't. The  
only other thing plugged into the same battery was the  
monitor. I have a habit of leaving it on.  That was probably  
enough to drain it after a few hours, I guess.

Based on all that processing you do, your system most  
certainly sounds like a data center!
