  Make sure the Battery Tender is NOT plugged into 110V before you hook it
up to the bike.
I used to plug the BT in while it was live and it would only charge for a
few minutes or so, then it would indicate that the battery was fully
I think it was Brian that pointed out to me that the BT needs to read the
voltage first in the bike and then plug it into the wall outlet.
