Those cumbersome-awkward-long-huge-battery packages from the big box stores are a definite hassle. Having them in these boxes keeps their polarity aligned and prevents leaks. They fit nicely in the drawer.

The plastic container is relatively sturdy. Helps to keep my rechargeable batteries organized and in one place. This way he always knows which batteries need to be recharged.

The aa contains 6 aa and 2 cr123 batts perfectly and the little movable divider is perfect. I keep one pack in my * box (box of items needed during a power outage) the aaa containers are for home.

One of the aaa storage box is damaged beyond use. It is not worth going through the loops to return the damaged unit. Too cheap to bother returning.

Bowed plastic molds and heavy warped separator makes the separator feature worthless. They seam very pricey for 10 cents worth of plastic. The downside is they are very fragile.
