1.5 Volt AA Battery Carrier

thingiverse

I conceptualized this rechargeable battery container, capable of holding a maximum of nine AA cells, specifically designed for 1.5 and 1.2 volt cells. I purposefully built it to keep track of the rechargeable batteries' charging status at all times, utilizing the FIFO (first-in-first-out) method so that they always exit in the same order as they entered. This storage system ensures the rechargeable batteries are maintained and used efficiently.
