I can't remember ever seeing a 2032 leak.

I've seen a few leak, but it's pretty rare. If it's going to discharge anyways, remove it.

Batteries should always be removed from devices before long term storage.

I agree that it's pretty rare to have lithium coin cells leak. I've seen at least one do so, but the leak was so slight that it didn't make it past the edge where the seal is, caused no damage.

Some internet posts state that it is isn't corrosive anyway, unless water is added, or very high humidity.

I suspect you are that nut I have encountered on other forums, who asks silly questions about how to pack and preserve everything, forever. Something something silica packets, in a vault at the bottom of the ocean. 😉

You should do your own research and stop wasting peoples' time.

Are there any chemical differences between older CR2032 batteries and CR2032 batteries made recently in recent years? Does this have anything to do with leaks that may occur?

If you’re going to store it for a long time just remove the damn battery.
If you’re not going to store it and are worried about the battery leaking buy a new brand name as in not from Ali Express battery and you’ll be fine.

Without knowing what batteries are in your country.
A brandname Battery which would be from a company that you recognize the companies name on the package.
