Just brought the bike out from the winter storage. Bike wont start without a jump. once i take the cables off the bike still runs. when i cut it off, then try to start. As i keep trying to start powere seems to weaken to the point that it wont even start. then back to square one. Battery is good.

Any idea??

 

battery not charged

takes a while to charge it back up

 

did you load test the battery?? sounds bad to me. what year zx6 is it???

 

that sounds like a bad battery to me too. my dead batter showed good on a tester after charging but wouldnt crank the bike over.

 

I'm voting crap battery.

 

bad battery bro, but i wouldnt try jump startin a bike with a car, it will fry the ecu box and wire harness, trust me i learned the hard way on another bike i own in the past

 

Never leave the battery in a stored vehicle. You should remove it and leave it stored in a cool dry place. Also plug it into a trickle charger every month or so to keep the acid charged. The battery went too long without a charge and the acid is now bad. Get a new battery and keep it out and charged during storage.

They are both 12volt systems, the only way you will cause any harm is if you hook them up backwards. You can jump start a bike with a car no problem.

 

Battery maintainer is the only way to go. Install a 12 cig/accessory plug on the bike and then all you ahve to d is plug it in once in a while or even once a week. The smart battery tenders are just that smart enough to not over charge.

 

+1 on all, dead battery man

 

votes have been counted. thanks guys. didnt know about the whole taking it out during the winter (and jumpstarting too). greatly appreciate the responses. do car audio and new to this bike thing.
