You have several options. I went with the stock AC since mine failed before warranty was out (got a free one right before the 3 year warranty expired on the car). There is an interesting option of a lightweight battery, will save you over 15 pounds.
I have never gone with an Optima only because they weigh more than the stock battery. I typically just buy batteries that are easy to replace if I'm on a trip, Autozone, Checkers, Interstate, or an AC Delco.
I just replaced the original battery in my '05 and it wasn't dead yet, I just thought it was time. I didn't want to get left dead on the road somewhere. I went with another Delco. I've never had problems over the years with Delco batteries. I have heard recently of many problems with the Optima batteries (no offence to those who have, and like, them). I was considering an Optima (basically just for the look), but when I heard of the problems, I decided to go with the old stand-by Delco.
I went with the Optima Yellow Top (model 34) because its a "Deep Cycle" and I go to the track (Drags) and between runs I turn on the fan with the motor off to cool it down, and yes it is about 6-8 lb heavier than the stock battery, but I rather have the peace of mind knowing I won't get a dead battery after 4 or 5 runs.. (I run the fan app 15 min after a run)
I have a 100 mile drive home, so I'm pretty sure the battery gets fully charged on the trip home. I also have a battery tender that I use in the winter if I'm not going to use the car for 4 or 5 weeks...

I haven't heard this... what are the reported problems with the Optima?
I choose the deep cycle because they can take the constant recharging that I need.
