Somewhat subjective battery question...UPDATE

As the subject says, I have a subjective battery question. I know there won't be a definitive answer here, but looking for your gut feel.

I'm going camping this weekend, and then again next weekend, at the same campground. Since I know the owners of the campground, they're going to let me leave my camper in a parking lot for the week so I won't have to tow it the 75 miles back home, and then 75 miles back the next weekend. There will not be electric to plug into for the week.

So, the question. Do you think my batteries will last the week running only the refrigerator? I'm hoping to leave whatever food and drinks inside. More importantly, I'd like to arrive the second weekend with the fridge cold, so I can avoid the 1/2 day or so it would take to re-cool it. I've never boondocked with it yet, so I don't have any history on battery longevity.

Details:

-I'll be leaving it at the campground unplugged from Monday afternoon until the following Saturday morning, at which time I'll be able to place on new site and plug in.

-The batteries will be fully charged when left. They are group 24, standard 12v deep cycle RV batteries.

-The batteries are about 3 years old, always maintained, i.e., water kept up. Except they were run down to dead once last year; forgot to disconnect them once for 3 weeks while in storage. I take them out at season end, and keep them on a Battery Tender in my garage.

-Outside temps will be between 80 and 90 degrees. Inside could hit 100 degrees. Don't remember if the lot is shaded or sunny.

-Plan on turning off all breakers except the fridge.

So what do you think? Might they last the 5 days or so?

Thanks for your thoughts,

Mark
