Thanks for the info, folks!

Tony, I'll keep all of that generally in mind. But for the most part, I'm not going to be too obsessive about this. Many of the batteries, like the CR2032's and the CR2450's, are going into smart home devices that VERY rarely need replacing and alert me well in advance of failure. If the batteries are messed up in storage It's really not the end of the world and I'll just order more. Same for if they lose some life on the shelf. As long as they're not corroded, if a battery can just get me through until a replacement arrives, or can run the device for 1 year instead of 3, I'll be fine.

And the rest of these tiny cells are generally for things I honestly could care less about, like the tiny compartments in various cheap kids' toys. Some of them would go into the speaker compartments for their books...if there were any that I didn't already want to rip the speaker out of...
