How long can you store tennis balls in a pressurized can without them losing their bounce?

Question

I'm thinking of buying tennis balls in bulk from an online supplier, but don't want them to go flat if they sit for a while.

Answer 1

Its not the time its the case , if the case is pressurized and will not loose pressure you can store them for over a year but if the can starts to loose pressure its another story , store them in a cool place not cold  or too hot .... this will keep the cans good till years to come

Answer 2

2 Months

Answer 3

About 5 months at the least.

Answer 4

i'd say about a few months.

Answer 5

If the cans do not lose pressure, and they usually take a long time to do that, it might be a couple of years or more.    I buy them by the case.
