anyone run their AC off a inverter & batteries

[universalexports]

well since most of the camp grounds around me have limited electric camp sites, I want to be able to use different power if needed,

I was considering running my AC unit (8,000 BTU) off of 3 or 4 deep cycle batteries and a power inverter, anyone done this? or have any idea how many hours (ballpark) you could get out of a setup like this, maybe a dumb question I know.
thanks in advance

OK, I answered my own question through a little research, ('m terrible with electrical equations)

If I had 10 deep cycle 130 amp hour batteries, a 8000 BTU AC unit will pull about 1300 watts, which would only last 5 hours, so it would take 20 deep cycle batteries to even get 10 hours of operation out of my AC unit, in short, it wont work.

you can get 200 amp hour batteries, but that would only give me about another hour or so,,,

here are the references I used.

How about one of those quiet little Honda generators? The 2000 watt version will run nearly 10 hours on a gallon of gas for under $1,200.
