A package I bought a couple of months ago has an expiration date of July 2023, I assume that the date errors on the side of earliest possible date the batteries will go bad rather than a more optimistic date.

A while ago I was forced to buy a package of sixteen. I don't use them that often, I only used two of them and when I wanted to use a third, all the others were bad. Don't recall but maybe 2.5 years I had the package.

Thanks much. Looks like those 40 packs won't be such a bargain after all.

The volume packs are aimed at hearing aid users who will go through one a week for each ear. Our cameras are much easier on batteries, generally.
