Then I hang them from a hook. There's no pressure on them anywhere but the hole where the reinforcement is. This eliminates shelf wear. It does take a bit of room to store them that way but if you have rare, expensive calculators, it's worth it.

Sorry I did not get this. How do you get rid of the batteries?

I use acetone on the back side to dissolve the glue without destroying the cardboard. Use the acetone on three sides so you can get the calculator out without removing the blister totally. To put the calculator back, make sure the acetone is totally dry. Use super glue sparingly to reattach the bubble.
