What is the typical shelf life of a CR2032 coin cell battery?

A good CR2032 like this Panasonic CR2032 has a shelf life of 10 years. That means it shouldn’t be stored more than 10 years before being used.

Obviously, using it before it lay around for 10 years will increase the useful life in the product where it’s being used.
