what about if you get a brand spankin new battery put it in the bike, start the bike, let it idle, shut the bike off and put it away for 2 months? would that permenatly damage the battery? since it never got a chance to cycle on a drive?

for right now im def leaning toward a new battery (again) and a new onboard battery tender

 

Yes. When I said drain the battery, I mean suck every millivolt out of it. If you caught it while there was still some charge in it, you might have been able to save it. But that battery is toast.

Don't mention that you left it like that when you go to take back the battery

edit: and don't waste your money buying a new tender. Pretty sure the .9 amp charge is for a slow charge. Most batteries have a much higher quick charge tolerance. Until you know something is wrong with the tender, why replace it? You know the battery is fooked

 

ya i was gunna tell the guy that i put it in the bike fired it up then took it out and it sat on a shelf lol well thanks for the help im gunna hold off on the tender for now, just get the new battery and hopefuly all is good! thanks again
