JC Penney Lifetime battery.

I'm on year 12 of an Optima, I'm waiting for it to need a replacement soon. Too bad they don't still offer warranties like this.

Advanced Auto gave me a 2 year warranty on wiper blades. He said just bring them in and say they leave streaks and I'll get a free set. It's only good 1 time, but at $26 a blade, at least I'll save a good amount of money. (I bought for multiple cars at the time)
