Freightliner refrigerator will it run the battery down?

You can get a small solar panel that will hook to the battery that might help out, otherwise get a pair of long jumper cables because it only takes @ 6 hours in some of them.

 

If your truck has a refrigerator it should have came with a LVD (Low Voltage Disconnect) that will disconnect certain circuits when the battery voltage drops below a preset voltage number.

 

A bag of ice or part of one is all you need to put in before turning it off when ever you shut down your truck in hot weather, just dont open the door to ck. an let cold air out too much?

 

The first thing it will cut off when the battery reaches the voltage cutoff level is the circuit to the refrigerator.

If you have four 900CCA Batteries, your refrigerator can run for over 10 hours before the LVD will shut it down.

If you're at home, just turn off the truck refrigerator, take the food out and put it in your home refrigerator.

 

That or hook up a trickle charge to your batteries
