Dual battery question
I'm going on a camping trip, but instead of using white gas or propane, I'm going to use 12volt appliances.
Here is my question.
Will both batteries be drained equally, or does one drain first then the other...only using the cigarette lighter, and accessories plugs? I have 5 of them in my Excursion, and all have a 20amp fuse. I may have a cooler on one, my Sirius on another, thermos bottle heater on another, one 15w florescent light, and be warming food on another.
To be safe I will be idling my engine to recharge the battery before I turn in.
Thanks!
