Jack,
This may not be as bad as they’re making it out to be. Batteries are required to be changed long before their useful life is over. Had a friend who worked for the Public Utilities Commission. He gave me bags of 9 volt batteries. They were required to change them every week, even if the testing device had not been used that week. I’d use the batteries in the same tester he used, and they lasted 9 months. And I did 4 tests every single day. Water company chlorine tester.

Just like products that are sold on Super Market selves... there is a expiration date on all those products..
Even if you bought some milk, eggs, bread a few days after the expiration date and don't seem to have gone bad are still edible.
They do that to CYA....

My son in law works for a large, unionized outfit and I’m amazed (and the recipient) of some pretty neat, out-of-date ‘profit sharing’

Batteries are shelf life items. They have a date when they are considered “expired” before they are installed. Once they are installed in equipment, they also have a standard useful life based on the battery type and the typical draw of the equipment they are in. Just because they are past their shelf life or installed useful life doesn’t mean they won’t work. These designations are somewhat arbitrary.
