How do you keep your battery from going dead with refrigerator running?

Yup! Just plug fridge into it then plug timer into inverter. I have mine set to run a few hours on Saturday night and turn back on early Monday morning. Freeze a couple of bottles of water in freezer to help keep it cold during shutdown time.

APU, Opti-idle, or shore power are the easy solutions that do not require you to empty the fridge. They all have associated costs though.

 

why?

The only thing that they do is allow more deep discharges and recharges without ruining the batteries.

The best solution is this - ​

When you park your truck, you take out all of the food that can be ruined and

TURN OFF THE FRIDGE.​

You can fill a couple of gallon freezer bags with ice, that’s actually what I do. Bonus: they don’t leak!

 

I empty out the fridge for the weekend.

 

Truck batteries were not meant to be used that way, unless you have an APU, which will turn on automatically and charge the batteries when low. Your truck batteries will go dead every time without a setup like this or similar. You can park near an outlet and use a long extension cord to keep your fridge running.

 

You'll end up losing cranking power in the winter with them, marine batteries aren't built to work that way, I've had several different things with those pile of garbage in them.
