I have a 2010 Road King Classic purchased new in 2011 (left over model on the sales floor). Bone stock and runs like a Swiss watch. I've stored it at the dealer over the past 2 winters with a Battery Tender on it, and its plugged into the Battery Tender at home when I'm not riding. Went out to ride on Sunday and it would start. Just a clicking sound, like when a starter goes bad on a car. Full lights, instrument lights, horn all worked fine with no dimming. It just kept "clicking" when I hit the start. Dealer trouble shooted it and said the battery was done. Cold Cranking amps were way down (tested under load). Anyway, after my long story here, all I'd like to know is did I just have a bad battery from the factory or is 2 years a normal life span for an HD battery? This is my first Harley, and I've only ever had imports with my battery's all lasting 4-5 years with no problems. If it matters, I was using the small Battery Tender Jr. trickle charger. The old battery seemed to be charging fine. After a ride I'd plug it in, red light on the charger for about 2-3 minutes, then it went to flashing green. Only 2 years for a battery is pretty bogus if you ask me!
