How do you guys have you battery switches set when your on the hook with radio going all day. Thanks

You should have 1 battery that is used for your tunes. Set the switch to that battery. Then if you run it dry you can move your switch to the other battery and get started. Then once started you can move back to both to charge the "house" battery again.

I do the same, and I usually mix it up on which battery I use for the stereo, when I am going out on consecutive days. I run 2 amps, but I never run the refrigerator. Does anyone know how much power the refrigerator uses? It would be nice if I could pull off using everything. I am currently running two brand new Interstate series 27 cranking batteries with a switch.

I also have wondered how long the refrigerator will run on 12 volt power without recharging.

I would suggest a deep cycle for your "house" battery. They are made to be drawn down and recharged were a starter is only made to be drawn down a small amount.

I could get about 24hrs out my fridg back in 95.
Today, with improved efficiency newer fridg, I have gone 48 on 2 house batteries and still had frost in the ice box. I had forgotten to plug in the shore power.

I have done the same in my 97 382. Turned it on on a friday and got rained out till sunday, boat started just fine!

I store my boat at home and I have a 30A plug in for it.
What I have thought about doing is, turning on the fridge the night before while plugged in then letting it run on 12V for the following day while on the water.
Sounds like I shouldn't have any problems with that.
No more soggy sandwiches.
