The factory battery is 730 CCA, it's a H7 (94R group) size battery.
You can install an H8 (49 group) size. One of the highest capacity American made battery you can buy is the Odyssey 49-950

Thanks, I was wondering the minimum requirement. Advance sold me a new battery today because my OEM (730 CCA) was only showing 500 CCA. Just wanted to know if they were legit or do I have something else going on…

Assuming a fully charged battery you were 68% of battery rating, yes it needed to be replaced.

For a wet cell battery, typical lifespan is about 4-5 years. Sounds like you caught the battery in time before it left you stranded somewhere.
The cranking amps for my EcoDiesel is under 250 amps as there is a fuse on the power that feeds the truck/starter. I'm pretty sure the Hemi has a similar fuse
