When the battery wears out, what exact type of replacement battery does it need?

We use a 12V, 10 AH Lithium Battery. Hope that helps.

Do you have an online user manual and instruction?

You can find the instruction and user manual here: https://nisplaysports.us/pages/instruction

why does my ball NOT shoot at the same height and location?

It is likely due to using a mix of new and used tennis balls (pressurized) with the ball machine, as they have different pressures and will shoot at different heights. There is nothing wrong with ball machine, and it is normal for all tennis machines, and the resolution is simply to replace them with new tennis balls or use pressure-less tennis ball.

what's the return policy?

We offer free returns and exchanges for any broken or defective ball machines. However, for any other returns, such as no longer wanted, the product is not as expected, etc...you may return it to us in “like-new” condition within 30 days of purchase, subject to a 15% restocking fee.
