Tennis Ball Saver will not remake your used tennis balls to a new one. But it can slow the process of flatting out. Therefore tennis balls kept in Ball Saver should be worn out later than balls kept in a tennis bag.
Thereof, how do you use a tennis ball saver?
The Original Tennis Ball Saver
This device will hold up to 3 tennis balls at their original pressure of 14 PSI. The pressurized container prevents air from seeping out of your tennis balls resulting in new, bouncy balls every time! To use, simply add your tennis balls to the container and screw shut.
Hereof, what pressure are tennis balls stored at?
Why do tennis balls stop bouncing?
When the ball hits the ground, the side of the ball squishes inwards and the air on the inside of the ball pushes out again, and that’s what pushes the ball back up off the ground.
Unlike other types of balls, tennis balls feature higher air pressure on the inside rather than the outside. The pressure pushing against the inside of the ball sits at around 27 pounds per square inch. In comparison, the outside air pressure creates a force of just 13.7 pounds per square inch.
Playing at a recreational level, a can of pressurised tennis balls will last anywhere between 1-4 weeks of light to moderate play. If used for competitive tennis, a pressurised set of tennis balls might last as little as 1-3 hours. Pressureless tennis balls can last 1 year and maybe even longer.
Keeping the tennis balls unopened is the best way to keep them pressurized. Once opened, tennis balls will start to lose their pressure. To keep used tennis balls pressurized, make sure to keep them in a pressurized storage container at room temperatures.
