Fast question for everyone.

My truck battery dies if I leave the truck for more than a day and a half off. Only item that is powered is the low power usage mini frig.(mini as in 4 cans of soda and a small pack of lunch meat mini)

This normal? Techs can't find any faults, but it's service is handled by a 3rd party as it's only a free rental unit till new trucks arrive. I left it Friday, tech did some test drives Saturday, and this morning the truck was dead as a nail.

Normal? I traditionally use the switch to cut all power, but didn't this time considering the truck was moving and running for a large portion of the 2 days off.

Afraid so sir, I have a 12 volt cooler and thats about how long it takes to kill it.

Dang, I didn't realize this massive battery banks would be killed off so quickly. Well, that's at-least reassuring. Moving forward I'll just switch it off if I'm not gonna be around the truck personally.

Appreciate the info.

Hmm yeah I don't think that's normal at all. I leave my truck off when I'm home. I have a 1.7 cu fridge from Walmart that stays plugged up and stays running. I've left it for 3 days on multiple occasions and didn't drain the batteries.

Sounds like one or more batteries might have a bad cell.
