Gridfinity Stackable Battery Storage for Cylindrical & 9V Batteries (AA, AAA, AAAA, C, D, CR2, CR123, MN21/A23 & 9V)

Update on Jan 25, 2026: - Partial Height Bins are now available for CR2 & CR123A batteries.

- AA and AAA bins have also been revised to have an additional compartment.

- High-capacity bins have also been added.

Gridfinity Stackable Storage for Cylindrical & 9V Batteries There are lots of bins for holding batteries, but not that had the same core features as the coin cell containers I am using (from EricS on Makerworld): - Stackable

- Labeled

- Easy to access batteries

As a result, I created a set of complementary bins for AA, AAA, AAAA, C, D, 9V, CR123A, CR2, & MN21/A23. They have been designed to hold a standard number of batteries, plus a few more. That way when running low, a new pack of batteries can be added without having overflow. They come in two main varieties, which are described below: Partial Height & Full Height. Full Height Bins Full height cases have the ability to have containers stacked above them. However, they do lose some functionality as removing batteries is not the easiest. Below are specifics on the bin sizing: Battery Capacity Size (X,Y) Height

9V (10x) 10 2x2 9U

AA 31 3x2 9U

20 2x2 9U

Rechargeable AA 20 2x2 9U

AAA 40 2x2 8U or 9U

19 2x1 8U or 9U

AAAA 12 1x1 7U

15 2x1 7U

C 12 3x2 9U

6 2x2 9U

D 6 3x2 10U

CR2 7 2x1 5U

CR123A 14 2x2 6U

MN21/A23 6 1x1 5U

Additional Notes about Full Height Bins - AAA bins are available in both 8U heights and 9u heights. They are functionally the same - the only difference is that the 9U height has the battery storage compartments offset 1U taller so that the top of the bins align with the tops of the AA bins.

- CR2, CR123A and MN/S23 bins: If you want them to be the same height as the other full height bins, I recommend printing empty 3U or 4U bins for them. Using a riser with these batteries is not recommended. The batteries are shorter than the respective riser, resulting in the batteries being able to leave their compartments and possibly short out.

Partial Height Bins Partial height cases have the side walls ending just above the labels. This allows for easier access to the batteries when they do not need to be stacked. These bins are still stackable using risers which are included. Additionally, the top ledge of the bins is gridfinity standard so empty bins are still stackable. Risers are also interchangeable with any other equivalent sized bin. See printing notes for details about risers. MN21/A23 bins are not available in partial height. As these batteries are higher voltage (12v) a partial height bin is not planned. Battery Capacity Size (X,Y) Height w/o Riser Minimum Riser height* Height with Minimum Riser
