i have been chasing the 30 to 50% state of charge issue around 3-6 days of truck sitting and not driven.
i have the bagm 48h6 760 battery and while looking to find a bigger capacity battery i stumbled upon page 33 of the body builder spec book that states lariat/king ranch/ platinum and tremor get a BAGM 94RH7 800 battery vice the 760.




waiting on dealer to open and see what they say

fixed it

 

This is the chassis battery, located under the hood, that came in my 2022 Power Boost. BAGM 94RH7-800.

 

That TINY difference in battery capacity should in no way be related to the 'problem' you describe.

 

Bottom right on your chart 730 CCA on King Ranch V8 engine.

What engine in yours? 3.5EB, 3.5Hybrid,800CCA or 5.0 V with 730CCA

 

Living in Texas you don't need to worry about an extra 40 cca. And like Bajaman said above your problem is not related to that. I wonder if the battery was part of the supply chain issue and it was decided that they would replace it with the 760. Dealer may find that the battery is defective, which could be the case and may fix the problem. But I would not worry if they install a 760 again.
