Re-pressurizing Tennis Balls The effective life of a tennis ball for the average user is about 3-5 weeks. Tennis balls are pressurized to increase their bounce and the purpose of a pressurized can is to ensure that the balls stay fresh until the can is opened. If the balls are kept in a pressurized unit, they can be used indefinitely without consideration for material wear.
