Re: New optima!
Good to know about the optimas! I also have heard a lot of good things about them as well. For me its going to be a toss between the ones that are sold at costco or the optima which is also sold there but i dont think they have the 34R.
I had the regular costco one in my parents previous cars as well as my olds and they all lasted over 6 years. By that time the car was also older and the batteries went with the cars so i dont know how long they would have lasted. The fathers intrepid (last year) and mothers WJ ( 4 years ago) have costco batteries in them and well no problems yet. So thats a good to note purchase as far as i can tell so far.
Oh and i pretty sure i read somehwere that the company Johnson Controls makes the batteries for costco. I guess they are supposed to be a good manufacturer?
