Quick question... I left my battery connected for over 2 months and now it has died. As I have not ridden the bike for that entire period. I tried to charge it over night and start her up in the morning but to no avail. I tested the voltage and the reading was still really low. (less than 3V) Will I need to buy a new battery or will this old one still fire up either by charging it for longer or jump starting? The battery was new only 8 months ago and had been running fine up until the long break. Ok it wasn't really that quick a question... your help advice is very much appreciated.
