Has anyone bought an upgraded battery in the past year or so? What exact model do you have and would you recommend it? I was looking at the Optima Redtop 35 series but seen some negative recent reviews. I have a Buick Super with upgraded stereo and want to get the maximum CCA that will still fit in the stock location.

 

April of last year I put this: Optima Batteries 8020-164 35 RedTop Starting Battery in my Impala SS and haven't had one problem.

Thanks I appreciate it.
