Nowadays most batteries are just rebranded products from other places (China). I've always had good results with DieHard or Interstate batteries (same company I believe). Even Walmart batteries (Everhard? Lol) work pretty good for the money. Optima are nice but I've seen them fail too.
I'm in the boat of getting the best battery with the longest warranty for the price. Battery makers have been getting better with their life expectancy plans. When they warranty it for 84 months it will last 85 months. The question is who do you want to deal with when it comes to replacement or purchasing.
Costco used to be good but I think they've changed their battery policy to pro rate months. So nope you can't buy a battery, wait 4 years and return it for a new warranty; the will pro rate the previous months onto the new one. I don't know about Walmart. I'll get batteries for people who don't care and for the price and return it can be hit or miss.
I say just go back to Toyota. It's about the same as Sears (maybe not as good as a Diehard) and it has an 84 month warranty. They'll honor it for the most part with little hassle.
