What would be the expiry date of batteries?

Bought sept 2019. Expiry date 12, 2021. No idea what today's purchase expiry date would be.

Could you please tell me the expiry date of these batteries. Thanks

Can't remember exactly but know it was approx 18 months to 2 years

I have a number of watches that have stopped working all at the same time - stupid question I know but are all watch batteries the same?

No, there are many many different watch batteries, they are not all the same. Check the back of the watch to see what battery it needs.
