I have a 2024 F250 King Ranch Tremor w/ a 7.3 gasser. I got both my batteries replaced under warranty after 6 months. Ford tested them and they were bad. Indicators were on the screens that the batteries were "low" and they would not charge even after 60 miles on Interstate. Maybe do your own battery testing from an independent shop.
My point: some of these trucks shipped with bad batteries.

I had this happen in a Mercedes a decade or so ago. Light switch was bad. It was an AGM battery, they replaced it "just in case" even though it was holding a charge fine.
I had this happen on my F-150 a few years ago, my knee bumped the light switch when getting out and turned on the parking lights. It took well over a day of sitting like that to kill the battery (security camera showed what happened). That was a conventional battery and it was under warranty but it still lasted a few more years.
Have a 94 F-350 7.3 PSD that sat for 4 years without being touched, batteries were at 10 volts, charged up and still holding a charge months later. I just start it every week and let it idle a while, but I have got to get around to solving the top end oil leak while running and haven't had time.
Harley's have had AGM in them for a long time and I've never had issues with them dying in the winter and I even dropped one 6 ft from the ground and it still lasted 4 years. Those batteries don't have much wiggle room on them.
Since the light switch reverts to Auto, there is always a chance you did this. I don't know if the late models cut them off after a while.
If it happens again, then you got to troubleshoot it, may just be a fluke/accidental drain that happened.

I went to start my 2024 F350 yesterday after sitting a couple days waiting out the snow storms moving through and realized the truck would not start with the Pass App or the key fob. So I went out to get in it and even had to use the emergency key to open the door. Everything was dead, no lights no nothing. I popped the hood and and put my DVM on the battery and it was reading 4.1 V. Dead as a door nail. Its a dual system and both were dead. Fortunately I had a booster and was able to get it cranked. I only have 1200 miles on this thing and should not have this problem. The temps did get down in the mid teens a few nights but that shouldn't kill these new AGM batteries. These are new factory batteries. Going back to the dealer to see what they say. Anybody else have starting issues during this cold snap?
