The APC Back-UPS RS 1500VA LCD that I got in July, 2008 (product page) has served me well. It's an 865 Watt, 1500 VA unit that gives me around 18 minutes or so of battery powered backup when it's new.
A few weeks ago we lost power, and my computer didn't last very long. When power came back I noticed the battery was behaving poorly, and due to its age, I bought a replacement from ATBatt.com.
I left the batteries to charge for over 16 hours (per the manual), and booted the computer to find this:
nnIn other words, either my UPS somehow went bad OR the batteries I received are bad. I think it's likely the latter, and initiated an advance replacement with ATBatt.com1 as they agreed it's likely a bad cell.2
I have another APC UPS (it's either this model or this one) downstairs hooked up to our TV. It draws 300 amps when it's running, roughly 35%, and has a runtime STILL (several years later) of 15 to 18 minutes.
The current model sells for $189.60 at Amazon, but I took a chance on a CyberPower unit that should be roughly the same: the CyberPower CP1500AVRLCD Intelligent LCD 1500VA 900W with AVR Tower UPS. The reviews are pretty solid, and the unit should be almost identical to the one on my TV at $40 less.
My APC? I'll probably probably take it downtown to use at Golf Evolution. We could always use another plug or two down there, and the battery back up will be a nice bonus over the surge protection we have now.
