How long ago is, "not long ago?" How do you know the battery is fully charged up? Gotta get some basics down solid before anyone can help you.

i know that is not the battery because one year ago i have the same problem. The scooter stayed a long time without start, and when i tryed the scooter didn't started and i discharged the battery. Then i buy a new one, and the scooter didn't started. I had to try many times and finally it started. Now i have the same problem, and once i start the scooter if i stop it and i try again the scooter start without problem, that means that it's not the battery.
