My new battery arrived yesterday. It's a Bikemaster AGM battery. WOW!! That thing is awesome. It spins the engine like its a kids toy pinwheel. They are supposed to hold the charge really well, and don't sulfate when sitting idle for several months. The local Cycle Gear ordered it, and was $68.00. Well worth the wait (back-ordered for two weeks). It charges with a simple trickle charger. I think my days of $35 WalMart batteries is over............
