A few years ago I purchased a new ACDelco battery for my Cadillac. It lasted about 13 months. Took it back to the dealer, they fiddled around for over an hour and determined that the battery was indeed bad.
Since it was still under warranty, they did some creative "adjusting", and determined that I needed to pay about 75% of what I paid for the battery a year ago, to get a replacement. They said it was prorated.
I asked, if/ when the new replacement battery died, what would be the warranty ? Dealer replied, just the remaining warranty from the original one, and that I would have to pay the "prorated adjustment" again, from the original purchase date.
I will NEVER purchase another ACDelco battery again. !!
You would do better by purchasing a Wal-Mart battery. Much less initial cost, better warranty offered, and they seem to last beyond the warranty period.

I have one in my '94 MR2 that's over 6 years old...
Couldn't agree more, had a 2 year Walmart battery last 11 years in my 77. But that said, I moved to Australia, no Walmart here. needed a battery a little over 4 years ago.
Bought a AC Delco Battery as side post batteries and nearly impossible to find over here. (Had to have one shipped up from Brisbane). Really had no other choice unless I wanted to change out my battery cables to top mount.
It's now over 4 years old and going strong.

One of the few, and the largest, remaining automotive battery manufacturers in the United States is Johnson Controls. Johnson Controls makes 65% of the automotive, truck, and marine batteries sold in the USA. They make the batteries for Interstate, Wal-Mart and AutoZone. However, from Louisiana to Southern California the Interstate brand batteries are made by a Johnson Controls manufacturing plant in Monterrey, Mexico. In the other states, the Interstate batteries are made by Johnson Controls in the United States. If an Interstate battery is manufactured in Mexico it is required by law to have a sticker on the top of it that says “Made in Mexico”. If there is not a sticker, it is made in the USA at one of the domestic Johnson Controls plants, and that "Walmart" battery you're buying may not be that bad...
As some have mentioned the Dual Terminal (DT) battery is a good choice. I personally, put the Group 78 battery in since it has more reserve capacity. I buy all my batteries from Sam's club now. They sell a Duracell brand that is around $130 for a flooded lead acid.
The AC Delco battery I bought a couple yrs ago, I recall was made in Korea. Its been a great battery so far. I like to have a couple dual-post batteries around to fit various vehicles.
Best practices: (Keep charged up. Never let run low) and they'll last a long time.
