What is the load of an AC inverter on a battery?

Asked by JeanPaulSartre (5779points) September 22nd, 2010

If I have a 9 Amp (peak) load (@ 1100 Watts, 115V) AC running from a 1500W inverter, and the inverter is powered by a (12V DC) 18Ah battery, will I get 2 hours (approximately, at peak) of run time, or does something in the inverter alter this draw in a way I’m not predicting?
