Which battery 2023 3500?

Batteries died today at 2.5 years. Made in Brazil! Sheesh. Not one mark on either battery saying what Group Size they are. My best guess is Group 94R H7. If so, probably get Duracell at Sam's.
Is that correct????

Longest warranty H7 AGM you can get. I did Walmart Platinum AGM 4 year.

Ended up with Sam's Club Duracell AGM 94R/H7. $199 for AGM.

I always buy the AGM batteries at Walmart. $179 each last year when I bought them.

Since AGM batteries use a slightly different charging specification, I had to change the computer in the truck to "look" for AGM batteries. This was easily done with the ForScan app. I wonder if Rams need the same thing done with AlfaOBD or similar?

Where did you make change in the computer for a AGM battery?
