6.5 years on a battery - new personal record!

I've had batteries last 6-7 years but they have been the more expensive AGM batteries. I got away from the old lead/acid batteries because of corrosion. Started using them in my race cars (in the trunk where the weight did the most good), then my trucks. Sears DieHards were my favorite when they were made by Odyssey. For the last several years I went with Walmart AGM which seem to be the best bang for the buck in my trucks.

What type/brand have you been using?
