The batteries may have bad cells that will not allow a full charge. This can happen if the scooter has been stored for a while or if the charger has remained connected 24-7 for a long time. Try replacing the batteries; cycle them 1-2 times to ensure they will take a full charge. (This means run the battery down into the red before you put it on the charger for 8-12 hours.)
