Aaron, that sounds about right extrapolating from my experience. I have my AVR-3311CI (driving 7 speakers), an AMP-100 (driving 4 speakers), and a TiVo Premiere Elite all on battery-backup outlets on a CyberPower CP825AVRG (450W). The highest power draw I've been able to measure has been between 130 to 140W, and that's at ear-splitting levels in the main zone; otherwise it seldom goes over about 110W (JD pretty much hit it on the nose
). I have the rest of the AV gear in my main zone on a separate CyberPower CP550SLG (330W) with the SW on a surge-only protected outlet. I like CyberPower for their user-friendly PowerPanel UI, which allows me to monitor battery performance via USB to a laptop without having to access the UPS itself, which sits out of view behind my wall unit.
I don't know what your requirements are, but I am jealous of the resources you are devoting to UPS backup. I know you've had a little bad luck lately with water damage and a broken windshield, and it's too bad your UPS's couldn't have helped with those incidents.
BTW, as you know replacement batteries--particularly on the larger UPS's--can be rather expensive. I've had good results buying non-OEM batteries from this eBay seller
. If they carry the suitable battery for your 1300/1500VA UPS's, you can probably get replacements for around $20 shipped, which is about one-half what you'd pay at a retail store.
