Here is a hard to deceifer list of what manufacturer makes what brand battery

Motorcraft, please see Johnson Controls
I scrolled the whole list, and never noticed Mopar.
perhaps they stock up on Mopar stickers and run down to the local Autoparts stores, slap a sticker over some other label, and ad 15$ to the price.
Battery life is determined by how much of its life it gets to spend as near as fully charged as possible.
The bestmade battery that lives at 80% charged will not last as long as the worst made battery that gets to live at 99%+ charged.
How well the vehicle charging system mates with the needs of the particular battery to reach absorption voltage for the time required to maximize specific gravity is a huge factor.
How the car is driven, how often and for how long, and if any significant battery depletions occur, determine lead acid battery life.
Now, this wont change any minds, as most minds act like alternators are instant perfect battery rechargers which is far from true.
Vehicular parasitic draw is another huge factor in battery lifespan.
Another factor is we do not know if the battery JC makes for interstate is the same quality as the one they make for motorcraft or the one they make for wally world, or the Autocraft batteries they make for Advanced or whomever sells this label, currently.
Do they have different plates thickness and densities and numbers they throw into each cell of the battery, or are they all the same internals stuffed in a slightly different colored case with a different sticker?
Only somebody at JC could say. Don't hold your breathe waiting for an answer.
And Exide is making at least some of the batteries wally world sells, in some locations of North America.
These 'who make the best battery' threads crack me up. We'll get another in another month, and few of the replies will be based on any fact.
Batteries are rented people. The length of that contract is up to the owner, and their vehicles ability to recharge it fully as often as possible.
Praise the battery brand if you need to, but those with outstanding lifespans from batteries should be more proud of their vehicle. OEM batteries could certainly be made to a higher standard, perhaps not. The new vehicle's alternator charge circuit could be creating a more favorable charging pattern too. Add in some age and oxidation to the connections and wiring between alternator and battery causes more voltage drop, and recharge performance dwindles.
