I'm not into electronics and don't know how to do the calculations.. Hope someone will be willing to help me.
I have an AC heating device that draws 500 watts intermittently. I'd like to be able to use that on a camping trip using an inverter and a couple of Deep Cycle batteries.
How many hours of service can I get out of the batteries before they drop too far to use? Let's use a battery that has 800 Cold Cranking Amps as an example? Regarding the intermittent drawer from the heater.. I don't know what the OFF time is when it reaches temperature and starts to cycle.. but, I'd guess the actual ON time is what I'm interested in.
THANKS for your help
