Well, I got my bike prepped for storage at the end of last year, pulled the battery out and have left it since.
I went and picked up a charger today at Cdn Tire (6A manual charger) to get the battery charged up so that I can ride the bike up to my step dad's to deliver it this weekend.
Did the "quick charge" for about 45 minutes - ammeter thingy said it was charged (figured that's about right because the battery says a quick charge with a 4A charger should take an hour), then threw it in the bike. I turned the key, headlight came on, I'm thinking "good start". Go to start it up, hear a "click" then a partial turnover, then "click" and then a small pume of smoke coming from the positive terminal on the battery.
What did I screw up and how can I fix it?
