How to Revive Dead Tennis Balls

Maximizing ball pressure is important to reviving a tennis ball back to new quality

What is tennis ball pressure?

Tennis ball pressure is the air within a tennis ball that affects the speed, bounce, and even your playing abilities. The best way to tell how much pressure is by bouncing it on the ground or squeezing it with your hand. Flat tennis balls have little bounce and give in easily when squeezed. Good tennis balls have a good bounce and are decently solid.

 

How to Maximize Tennis Ball Pressure and Revive Them Effectively

Maximizing tennis ball pressure is important to reviving a dead tennis ball. The idea behind this is when high pressure is applied to a tennis ball, air will seep into the ball fast, thus reviving it. More information regarding certain steps in these tennis ball repressurizing methods can be explained further below. We highly recommend using the Advanced Tennis Ball Repressurizing Technique!

Regular Tennis Ball Repressurizing Technique:

1 . Group tennis balls into a family based on similar pressure by squeezing the ball.

2 . You can compare your tennis ball to a new tennis ball to get an idea for how much air should be added.

3 . Put the tennis balls in and input air between 18-30 psi.

*Completely flat tennis balls need around 18-20psi

*Average tennis ball need 20+ psi*

*Close to new tennis balls need around 30 psi*

4 . Flat or Dead balls need about 18 psi over and slowly increase pressure over its recovery time.

Estimated time to restore air pressure to quality of new tennis ball:

Close to new tennis ball (1 day)

Average tennis ball in (2 – 10 days)

Very dead tennis balls (10 days – 2 months)


Advanced Tennis Ball Repressurizing Technique for ZT-1 and ZT-2:

1. Group tennis balls based on similar air pressure by squeezing the ball. This is especially important for the advanced repressurizing technique.

2. Input air into Zombie Tube and watch the tennis balls. The air pressure point at which the first tennis ball collapses, minus 2-3 psi, is your optimum air pressure.

For example: If the tennis ball collapses at 25 psi, you should repressurize the tennis ball at 22-23 psi.

3 . Release and refill the Zombie Tube with air to the optimum psi number. This is the fastest way to repressurize tennis balls.

Estimated time to restore air pressure to quality of new tennis ball:

Close to new tennis ball (less than 1 day)

Average tennis ball in (1 – 7 days)

Very dead tennis balls (7 days – 1 month)


Advanced Tennis Ball Repressurizing Technique for ZT-Elite:

1 . Group tennis balls based on similar air pressure by squeezing the ball. This is especially important for the advanced repressurizing technique.

2 . Input air into Zombie Tube and listen very carefully for a faint pop noise. Once the tennis ball makes a pop noise, look at the pressure gauge to see when the ball made a pop and remember the PSI number from the pressure gauge.

3 . Release and refill the Zombie Tube with air to the psi number before the point the tennis balls almost cave in (makes pop noise). This is the fastest way to repressurize tennis balls.

Estimated time to restore air pressure to quality of new tennis ball:

Close to new tennis ball (less than 1 day)

Average tennis ball in (1 – 7 days)

Very dead tennis balls (7 days – 1 month)


Important Tips & Science Behind Our Steps:

The point at which the tennis ball is about to cave in from the air pressure is the maximum amount of force air can push into a ball. If too much air pressure or psi is pushing against the tennis ball, the ball will collapse and be unable to revived until enough air is relieved around it.

Extra information to grouping tennis balls

Grouping tennis balls based on similar pressure is important. Mixing flat tennis balls and average tennis balls and repressurizing them will result in varying bounce. Testing for similar pressure can be achieved by squeezing the ball or doing a drop test.

Understand how much pressure to put into Zombie Tube

Once tennis balls have been separated into groups based on how hard it is to squeeze or a drop test, compared the group to a new tennis ball. The flatter the tennis ball is, the less pressure you need to use for revival.

-If the tennis ball group is not too far in difference from the new tennis ball, 30 psi is recommended.

-If the tennis ball group has a big difference compared to the new tennis ball, 20 psi is recommended.

-If the tennis ball group is very droopy and literally dead, 15 psi is recommended and over time as the ball gets harder to squeeze, increase the psi up slowly or by one.

*Make sure the balls do not make pop noise or cave in the Zombie Tube or else the tennis ball will not pressurize*


 

*Helpful Tips*

-These instructions above are recommended for both new and veteran users of ZT Tennis Pressurizers. In other words, it’s fine to mix balls with different psi or keep them in the pressurizer for only a day. However, the revived tennis balls will have varying bounces. Have fun and experiment with what works best for you!

-Not only is Zombie Tube good for reviving dead balls, but also Zombie Tube is good at preserving balls. New tennis balls come in at 14 psi. Keeping the pressure at around 15 psi will help keep the new balls in pristine condition.
