I had about given up on the scooter battery. Trying to be gentle, I had been using the little "battery tender" charger and it was struggling. Came home last night and decided to give it one more try -- and it worked! Checked a couple of hours after putting the charger on and the yellow "Charging" led had given way to the green "Storage" indicator!
Picked up a new funnel for the oil change over the weekend, so now all I need to do is find the time.
