Dead Battery

Ugh, a week ago we had beautiful weather and figured it was time to finally get my bike in action. I tried to start it up and... dead. I realized I have forgotten to unhook the battery for storage. So I tried to charge it for several hours on trickle and nothing. I think my charger might be broken on that setting (works great for high Amp setting like my truck battery). I am going to try out Stephen's charger to see if I can get this thing going. It's a brand new battery... it shouldn't be dead-dead.
