Does anybody know who makes the best and the most affordable battery for the Tennis Tutor Jr? How much should I be looking at? I just bought the ball machine and I want to have an extra battery.

I didn't realize that they design the Tennis Tutor Junior battery to be readily swappable. My TT+ is not. But the battery can last a couple of hours on the court with no problem.

Take the old ones out or at least get to where you can see the battery's rating. I'm not exactly sure how many batteries a Jr. takes but if it's anything like the plus series, it takes two 12 volt, 7 amp/hr (ah) batteries. Measure the width of the battery posts and start shopping on the internet. I saw batterymart dot com sells them. YOu can also go to Radio Shack or an electronics store like Fryes. They're about $18 each. I'd opt for "heavy duty" if you can get it. When I had my 4 Plus, I replaced my batteries each year anyway. It was a small price to pay for optimum performance of my machine.
As volusiano said, you get a couple hours use per charge anyway so I wouldn't get any spares to keep around the house. Just pick new batteries as you need them. Each battery will have a manufacture date on it so I like to go pick out my own batteries and check the date on them.
