2022 platinum battery problems

Drove the truck the day before went out the next day battery dead . Took battery to get tested passed both tests , under load . Drove it couple more days went out dead again . Meter show 13.8 while truck is running . Charged battery and had it at 100% and went out next morning 70% . Nothing left on . Turned ac and radio off before killing it . Keep start stop off . Is battery bad without testing to bad ? Also it was 2022 platinum I bought brand new april 23 . Battery was almost year old . Not sure what to do , I feel dealership will keep forever cause battery test is good . Should I go buy aftermarket battery ? If so is x2 power batteries ok . ( not hybrid model)

 

Check battery under load while someone is trying to start it after it sits over night. Make them check battery underload.

 

When starting it dropped to 10.8 , just thought it’s weird sitting all night it went from 100% to 71% after 8-10 hours

 

I remember reading somewhere on the forum, there was a batch of bad batteries. Not sure if that is the issue though based on what you're saying. I agree it may be sensor related.

 

I had that with a 2004 ford once. Dealer had it 3 times for a total of 4 weeks and never found it. I accidentally found it when I heard a relay clicking in the back as the battery was dying. Replaced the bad relay and that was it.
