Foolishly left my key in on position and kill switched turned on had plans to ride and got distracted remembered hours later but it was too late. Would it be better to just buy another battery or charge this dead one? Bike is only 2 months old. After doing research I've come across the ANTIGRAVITY ATZ-7 RE-START BATTERY. So not sure if I should just replace my stock one with that since it seems like a good upgrade or just keep this and charge it.
