2021 Battery issues

[Calson]

Starter type batteries are not designed for deep discharge and if fully drained they are damaged and less able to hold their designated charge. The Ford BMS has problems unique to Ford vehicles that allows parasitic draws that can drain the starter battery to a zero SOC.

After replacing the H6 with a H7 and the H7 with two more H7 batteries and still having a dead starter battery in the morning I fixed the problem completely by trading in the 2022 F-150 for a 2025 Chevy Silverado.

Search for posts on battery problems for Ram, Ford, Chevy, GM, Toyota, etc and you will soon realize that the problem exists only for Ford vehicles (and not just the trucks). There are posts more than 10 years old regarding this problem with Ford cars and trucks so it is a known issue by the Ford engineers and only they know why they choose not to fix the problem.

I have a Ford. I fixed the battery issue.

You have a Chevy. Have you fixed your main bearing yet? I heard it's more involved.

Sorry, couldn't resist.

Reciepts?
7 days resting voltage

Current resting voltage a few minutes ago before starting the truck.
Yeah, 13V
Not saying it works for everyone, but it cost me less than $100 to put the whole issue behind me. (credit to many incredible fellas here and their meticulous research and generous sharing)
