I haven't had any problem with my Train's battery, but when I do I'm switching to Odyssey. I know several folks using these with excellent results and the one I had in my last bike was great. They feel like they have more cranking amps (starter motor turns faster) and you can leave them sitfor months and they still crank like fully charged.

 

+1 on the Odyssey. I've heard nothing but good from people who use them.
