Perhaps I am in the minority here, but in the 15 years I've owned cars I don't remember a time when I planned changing the battery. It was happens in the worst time, most frequently when I'm trying to get to work or home. So getting a new battery is always an emergency to get my car rolling so I don't get it towed or start accumulating parking tickets. Getting an eco-friendly battery is the last of my worries. I wonder how many folks out there feel the same and how this could impact a novel product like this going forward.
