There are hundreds of great Gridfinity solutions for batteries, but I couldn't find any that are stackable, so I set out to create my own. These stackable bins are designed for maximum density of storage and, as such, they don't adhere Gridfinity's “ease of access” philosophy.

There is a small divot at the bottom of each slot for the battery’s tip allowing for batteries to be stored tip down, keeping the negative pole of the battery visible to inspect for corrosion.
