At one time batteries were almost all made by General, Exide, and Globe Union. GU by far was the best and that same battery is still made today, but the manufacturer is now Clarios. These have a bunch of different labels, but the last reasonably priced one is Walmart Everlast. Not only is it likely still the best, it's also just about the cheapest!
FYI Die Hard and Interstates are identical to Everlast, but cost more money. Advance Auto used to sell all GU products, but now use whatever. They are not nearly as good. They fooled me a couple times before I wised up. They do still have the GU batts, now Clarios, but they are uber expensive Die Hards. I'm not paying twice as much for the same batt I can get at Walmart just cause the name used to mean something.
Since I don't have a Walmart handy, when I need a battery right away I go to NAPA who sell Deka made batteries. These are high quality batteries and may rival the Clarios products, but I've only recently had much experience with them since they never used to sell them in the Midwest. They do have a great rep though.
So, in a nutshell. Get a Clarios or a Deka product and you'll likely get more life out of it than any other. I live in an area that sees below 0 temps, but still those GU batts last 8-10 years for me. Warranties don't really mean squat, esp with a quality battery. I've only once in my life had to return a GU battery for warranty and that was back when they had 96 mo warranties!
In case anybody is wondering, I used to manage a battery warehouse, so it's kind of a hobby for me. Just don't get me started on how to recondition your batteries to get some extra life out of them.
