For the last 16 years I have put OPTIMA batteries in my cars when I replaced them. NEVER HAD ANY CORROSION on the posts or the trays. I am replacing the original in my '05 this week. Right now Farm and Fleet has the 34R for 129.99 and there is a 25.00 rebate from OPTIMA good through august 31st 2010. Not a bad deal for 104.99!
