I live in Chicago and so about Nov 1 I pulled the battery off and kept it inside until today. (4.5 months)
I don't remember if it was fully charged or perhaps it was low after my last ride. But now when I tried to ride today the battery appears to be dead. I have been charging it for about 2 hours and still no sign of life when I turn the bike on. I am hoping that it's just dead and will need several hours to recharge. Is it normal for the batter to go dead after sitting at room temp for 5 months?
