ARB fridge and a suspected weak Yellowtop battery - advice wanted

[Rev]

Good thought


Well, I have run the fridge for hours in 30 degree heat with no issues. It runs like a champ. I am camping this weekend so that will be the test. But it looks like it was the old battery. I think the reason the new one gave me trouble at first was due to it not being fully charged off the shelf. I should have driven the truck for a while first, or put it on a charger.

Update

Ran the fridge for four days camping without issue. (Clarification: the truck was driven twice during that time for about 30 minutes each time) Seems it was the battery.

Once I found it had turned off but when I opened the lid it came on and read the correct temperature, so it hadn't been off long . Maybe I jarred the cord.

In all fairness to my Optimas, this thread had me investigate my connections and supply to my ARB fridge. While I had no voltage loss all the way to the socket, my non-locking socket needs to get swapped. slight movements in my ARB 12v plug will cause voltage loss, which explains why I've had the fridge red error light come on so quickly sometimes. I don't think I could go 4 days on my yellowtop 34 group, but I'll be solving that soon with a permanent solar setup. Those Optimas will still get replaced with Sears Diehard Platinums thought when it is time. If nothing else, they have more reserve cap.

Clarified my previous post. I don't think my battery would do 4 days straight either. I never stay out of my truck long enough to find out.
