ON a few occasions now, even though the battery is fully charged, when I turn the bike on battery shows 0% charge. I have to take battery out for a few seconds and then it will show the charge. Secondly, it often will not take a full charge, right now it is 95% charged, and whether the battery is charged on or out of the bike it will not charge any more. On another occasion, it was 96%. This seems to be happening every couple of days now. The bike is new...it is a2015 model with around 500 km. Anybody have any ideas? Could it be a faulty battery?
