Yes sir!
Lucky I paid 38 CAD for the part at the dealership. I should have looked around.

Just hit 34k and my factory battery took a dump. Dead after work today. I noticed it was getting weak the last month or so. Replaced it with a oreilys super start agm H7 because it was in stock locally. Still an upgrade over the factory cca and capacity so I’m happy. Starts like a rocket now. Next time around ill go the H8 route. Thanks for the good info here.

So I was just reading through this thread this morning, and recalled that my 20 Big Horn had an AGM battery. Came home from work and, just out of curiosity, looked at the battery in my 22 Laramie, it is not labeled an AGM. I absolutely believed that a two year newer truck would have at least the same type of battery that my last Ram had. Anyone aware of any rhyme or reason to this?

If I'm remember correctly, the EcoDiesel will come with AGM battery.

56029635AC is a Group 94R AGM battery built by Johnson Controls. AGM's are still lead acid batteries, except they are sealed. “absorbed glass mat” AGM

I have been following this thread since the beginning, waiting for the day that I get that dreaded click but no start. After 3-1/2 years and 55,450 miles I had the pleasure of replacing my factory H7 flooded lead acid battery with an Interstate 49/H8 AGM purchased from my local Costco. Also ordered the proper felt battery shield/cover from my local dealer. Thanks everyone for the insight on the different battery brands, sizes and flooded vs AGM.
Just changed mine to the Interstate AGM H8 this morning after getting it fully charged. The shield from the H7 I was able to get over the H8 so no need to get a new one. I did notice when I turned the truck on on the 12" screen it was asking for an Unlock code which I thought was odd. On my initial few mile road drive I didn't get the sluggish response like the motor wasn't getting enough power (had the same thing happen on my '17 JGC that ended up being battery swapped out) and also noticed the voltages saying at 13v. Next run back to home it started at 13, went up to 13.9 at one point but then settled back to 13v again.

May want to consider returning it if you can. You really need an H8

Doesn't matter what screen you have. The H8 is actually the correct size for this truck. RAM went with the H7 to save money.
Not being a **** at all, if you have a 100% stock truck (limited) why do you need a H8?

You don't NEED an H8. That's just the size. There's plenty of H8 batteries with lower specs than high end H7. All else equal, an extra 6% CCA and 20 mins reserve capacity isn't gonna make a difference and unless you're running on your on battery alone frequently

It's not the size of the battery that matters, it's all about how long it stays up. Its all about preference.
