Johnson Controls makes a lot of batteries for a lot of places - Walmart, AutoZone, etc., but they work off of different specs for each. I used to work at AutoZone and learned a couple of things.
First, an Everstart Maxx would have been equivalent to our Duralast Gold. But it was lighter...thinner plates, meaning less resistance to vibration and corrosion, thus, not as durable.
Second, I got a LOT of complaints about exchanging an Everstart under warrantee. Best advice I have is if you buy the Everstart, keep the receipt. Keep the receipt. KEEP THE RECEIPT. And keep it at home, not in the car. Hear will fade the printing on the receipt and make it useless.
We replaced more Everstarts than any other brand - though maybe they were just more popular. We called 'em Neverstarts.
The usual caveat - batteries are kinda finicky. Some will last a week, others practically forever. Kind of a crapshoot. Whatever battery you choose, take it from the back of the rack, it's probably the freshest one. Check the manufacture date.
FWIW I have a 15 year old Optima red top in my Mustang. It's starting to get weak (probably from disuse), but still gets the job done as long as I don't have to crank it till the fuel pumps up to the carb.
