This is just an FYI post for everyone in the mpls are that have read that, as tony put it "50 page" post on exploding, leaking batteries on post 02 monsters and all S4's. I picked up a couple of mats from a local guy in Bloomington. They are $3.50 each. It was a 5 minute install and I see it as a piece of mind until I get a Yuasa or DNA comes up with the magical fix. You can get his number off of the www.batterymat.com site.
