Hi I was wondering if any of you guys can help me out. I have a tennis tutor model 2 machine and I don't know what kind of charger I have (Smart charger or regular). I know what the differences are between the two (smartcharger won't overcharge the battery) but I have no clue how they differ in appearance. Is there a big difference in what they look like? Can anyone describe how they differ in appearance? Thanks.
