I just had a similar problem with a 12 volt AGM truck battery. Although fully charged it would not start the truck however my very small lithium Ion battery power brick/bank would strongly start the truck. After much failed troubleshooting I took it to auto repair shop and they replaced the battery end cables connecting to the battery post and this solved the problem. There was nothing wrong with the starter, alternator or 2 year old battery.
I have a marine start 12 volt battery in my second nearly identical Dodge Ram 1500 that has performed perfectly now for 3 years and is $80.00 less than a standard 12 volt wet cell bat. Check those battery cables connection terminals as mine were rotten. Voltmeter and multimeter and other checks on the cable ends falsely showed proper start voltage flowing from the battery to the starter. Your mileage may vary. This info may be of help to others with battery start problems.
Good luck
