Interesting, but basically Exide's copy of an Optima. Unfortunately the 18 month warranty is a bit weak and they only have two models with any significant capacity, all the rest are well under 100AH. I just put a new VRLA battery from Yuasa in my wife's motorcycle, so I'm interested to see how it holds up. I've heard good things from folks with Harley's that have them, and that's a good thing since most Harley riders have about as much mechanical skill/knowledge as a 3-day dead eastern grey squirrel.
