ive charged my battery with the battery tender. it's just lower power and takes longer vs a standard charger.
for instance when i bought my Z, first thing i did when i got home was plug the battery into the battery tender. it had to charge almost 18hrs before it would float. means how low the charge was when the car was "new" and just sitting on the lot for about 3wks.
car was manfuactured in june09, landed in the usa in july09, arrived at my dealer first week of august, bought by me 2wks later.
