There are a lot of battery storage models, but all of them have slots for battery types I never use, so I made one that only includes the most used batteries in my household. It has an arrow pointing at one side which is charged batteries. The other side is for batteries that need charging or you can use it however you like.. I'm thinking of making another one for button type batteries.
AAA - 32
AA - 26
C - 7
