There are some very cool looking battery storage boxes in this forum and online.
These are not them. I just wanted to organize my new batteries and take them out of those dreadful rigid plastic/cardboard packs that require a jackhammer to get in to. So I made some boxes that do the job. They all have flat lids that fit fairly tight (you glue the smaller rectangle onto the larger one for the fitting part) and have been kerf adjusted for a fit that requires a few taps with a mallet to fully seat. I designed (and made) these for Baltic birch about 3 mm (mine is 3.06mm). I set the text outlines to score to save time. You could engrave them if you prefer.
If you just need some no-fuss boxes, these might do it for you. Enjoy!
the little worx zipsnip tool (that some of us got a while back for cardboard) does a great job cutting blister packaging… once you get it out of its own blister-pack!
