I think I am starting to have the dreaded battery issues on my (2nd) 2025 RAM Tungsten. I have had it a little over a year and almost 10K miles. It died out of the blue two weeks ago and was complete dead when I went out to it after just driving it 30 minutes earlier. I jumped it and no real issues since. However, I am not sure my battery is ever charging. While driving, I hover in the low 13V range. Is that normal? Can anyone else check theirs and confirm? Will 13.2V ever charge a battery?
 
I've had a lot of experience with car batteries in my past several Rams, my family's Rams and Jeeps, and other FCA products. Researched these to death and back.

If I were you, I'd preemptively swap out your batteries with a decent brand, such as Duracell (Batteries Plus), SuperStart (O'Reillys), or similar. The most reliable ones I've found tend to be made by East Penn (Deka), and are made in the USA. Duracell AGM batteries are made by them, as well as most AGM SuperStart batteries.

Many of the once-previously-great brands are shadows of their former selves since COVID hit; Enersys (Odyssey) are hit-and-miss (although their X2 line, once Northstar, at Batteries Plus seem to be better), Optimas are hit-and-miss since Clarios moved their production to Mexico, Interstate batteries (also Clarios) are hit-and-miss, etc. If you can find a Clarios-made battery/brand from their Germany plant, those seem to be much more reliable.

Before I bought it, according to the Carfax/Autocheck people, my truck had its batteries replaced twice under warranty for the previous/first owner. It looks new, but it says made in Malaysia on it. First time I've seen that on a car battery, let alone an OEM unit.
