Error Code P1674
Just got this error. Did some quick research and found that it could mean multiple things, one of them being a low/bad battery. I have an appointment in about a week for my dealer to take care of this but until I'm trying to get ready for possibily having to replace my truck's batteries.
So, two questions
1. Do you have any guidance on this error code as to most likely cause, etc?
2. What battery would you recommend if I do have to get new ones? I do know, I would like to go with AGMs.

I had a FORD dealer install the Motorcraft AGM batteries in my '22 F-350. There is a programming change that is needed when changing from Flooded Lead Acid (FLA) to Absorbed Glass Matt (AGM) batteries. I gifts the OEM FLA to a coworker with a '19 F-250 that wouldn't start without a jump in cold weather.
