I think I have over 10 Optimas laying around that are all bad (reds, yellows, and blues). I have been using the Wal-Mart batteries in everything. I generally buy the 5 year batteries and have had good luck with them. I know some will tell me they are crap and blah, blah, blah. I have 2 cars, 4 Diesels, Tacoma, Hemi truck, 3 Jeeps, 2 Blazers, and 4 buggies so I tend to always be charging or switching a battery.
Plus when I am wheeling or travelling there is a Wallyworld everywhere so replacement is easy.
