SOOOO, 2018 1500 5.7L. OEM battery is garbage, first "cold" week end of summer of 50 degree nights and security system told me low voltage of 11.7v after 5 days of sitting...when I had zero issues the entire summer sitting 2-3 weeks. Don't want to turn this in to a battery diagnosis thread, so let's just stay on topic.
I think OEM is 625-730 amp with 750 CCA. So definitely as high as I possibly can go above that. I KNOW I want AGM.
Actually having a difficult time finding batteries for this truck. Online half the websites don't have my vehicle (NAPA, O'Reilly's, Interstate, Costco). Believe H7 is the "Group" yet many other websites don't even have "H7 group" but also think it may be a 94R? Difference of like $10 below between the two I've found (and can probably find coupons). Believe they may both be made by same company?

Remember reading on here I believe about Deka, but can't find them anywhere and would like to stay away from Optima, read they've gone downhill. DieHard may also be good one but not sure where or what type of theirs to buy. Not fully ruling out Walmart, buuuut rather search elsewhere. Also read some have made an H8 work.
Really looking to see what you guys have had installed and highly recommend. Crazy amount of electronics and aftermarket electronics these days too and I let the truck sit up to 2 weeks sometimes, rarely even 3 weeks. I also have a 12v battery maintainer I'm hoping to continue to use with the new battery as long as it won't cause issues every day of the winter.
Side note, also remember reading in the past people having to get radio codes etc when battery has been swapped. Does this still happen?
And lastly, is it dumb to leave battery blanket on it summer? Cause any potential issues? More heat could cause battery issues I'd assume.
