Ball says they last indefinitely.
A forum member elsewhere said they last 5 years
What is it? |

I have some in my hand-me-down box that are over 20 years old and they are just fine... some others seem to have broken down and I did not attempt to use. They just came to me in the last few years so I can't really tell you if they were stored in different environments.
Reasonably cool/dry area they should last a long time.

as long as there is no rust on the inside or deterioration of the rubberized seal they will do the job.

| The ozone in ambient air could destroy the rubber sealing ring. If you store them in an airtight container in a cool, dry dark place, they will probably last for decades or more. |
