Scooter Battery Charger

Scooter Battery Charger
My Schwinn S-180 scooter has been sitting for about 2 years, unplugged. Why won’t it charge now?

The charge indicator on the charger is green when I plug it in and it remains green after I plug it into the discharged scooter. The scooter never charges. Is my charger bad or the scooter battery? I would really appreciate some input from someone who knows electric scooters. Thanks.

the battery wasn’t kept charged and after 2 yrs of nothing, it’s dead.
