AJC Battery Compatible with Tennis Tutor Junior 12V 7Ah Tennis Ball Machine Battery

The battery works well, charges quickly, seems to hold a charge well. My previous battery was so erratic in charging that I was afraid it was the charger, but buying this has reassured me that I simply needed a new battery. Fortunately, batteries are fairly cheap. I recommend this one.

This battery's terminals were wider than the original. I was able to make it fit. It lasted for 1 year. Ok, for the price. However, I got 4 years out of my first battery.

The old saying "you get what you pay for" applies here. I went the cheaper route to save about $30-40 ordering from these guys instead of directly from the Sports Tutor site. The first time it was fully charged (charged for 3 days), I was able to use for about 40 minutes worth of ball feeds. The next time, also on a full charge, about 30, the next time 15-20, and this last time it wouldn't even provide enough power to get the ball into the air. Not worth the money or time wasted putting it in the machine.

It was used to replace the dead battery on my Tennis Tutor Pro Lite. It is much cheaper than the one offered by the Tennis Tutor and works fine

Exactly what I needed. Works perfectly.
