My 2022 ram 2500 hd acting like the battery is going out slow rotation then click and all the dials flip and flops so I get someone to jump me and get it started like a dead battery. That night I started it twice and it started, the next day started as normal went to work went out 3 hours later same thing acting like the battery is bad so I put charger on it for 30 minutes tried but not quite one hour later it started went to battery shop testing showed just fine I don’t trust it at all anybody have any battery issues with 2500 ram battery or wiring glitch
 
Check all your battery connections and chase all the grounds down. Also put your batteries on trickle charge all night.
 
The starter nut was an issue on the 2022s i would say to start there if the battery tested good, also check the battery voltage next time before charging if it is indeed low then you may have a draw somewhere killing it at times
 
It’s a new battery? New to you truck? Trying to understand the title.

For what it’s worth, my battery tested OK per the shop’s inspection routine (with a photo of the meter reading) less than a week before I had the slow start and had to replace it. It was 3.5yrs old.
 
The OEM batteris are not the best. Most seem to die around three years. If they are load testing the batteries in the truck, make sure that at least one of the negative terminals is disconnected or they are testing both batteries together since they are wired in parallel. They will get a false good reading. By the symptoms it sure sounds like the batteries are going south. I don't think a bad starter connection would make the EVIC go crazy. Also a good idea as mentioned by @H3LZSN1P3R to check for draw somewhere.
