by Powerpax AAA Battery Storage Caddy, Black, Holds 12 Batteries (Not Included)

They work very well. It's like having a cartridge. You can begin a standard of which batteries are full and which are spent depending on the direction they are inserted ie: nipple up or nipple down. They hold the batteries snugly in place and they don't fall out. A great organizer.

These hold enough batteries for a week of camping headlamps at least. Put in button end first when they are charged and flat end first when used. Easy to see which ones are still good.

These are the best battery storage packs; I have tried several other brands and styles but settled on Storacell and have purchased a number of them.Storacell offers various container capacities & battery types, and several colors are available (I use different colors to distinguish between Alkaline, rechargeable NMH, and AMPTORRENT batteries).If you don't need waterproof storage for your spare batteries, go with these it will not be a wrong choice. They are quite tough, and battery access is ideal. Batteries individually lock into place with assurance and a positive 'click'.Also, you can insert the batteries with Positive button UP or Down, to indicate which are fresh and which are discharged.If you have an MBT-1 Pulse Load Battery Tester and insert your AA or AAA batteries with the Positive terminal DOWN (as I do) you can even test them without removing the battery from the Storacell holder. See the image testing a partially discharged AAA battery while in the Storacell holder.

It may have been designed to hold batteries but with how pleasing the loading is it's more a fidget toy.Pros:Good priceGood CapacityGood DesignCons:Having to buy more batteries and caddies.

So far I don't have any dislikes about this product. It is a streamlined battery organizer and so far has held up well. I bought two of them and put them through about 2 months solid of camping and working this summer. They are still in good shape and nothing has broken so far. I hate loose batteries or trying to keep them organized with a rubber band and ziplock bag. This is a helpful solution to that approach of carrying extra batteries. I would definitely buy these again. and do recommend them.

They hold in there easily and you push them out its configured so you can't easily contact the ends of the battery to other things like metal etc. Rather than a case or something where the batteries rattle and may fall out and spill on the floor this device enables one to securely store batteries that are also protected and when you use two or three of them the rest of them are held just find .. because each battery has its own spot ... wooo hooo ...

I absolutely LOVE this and all other Storacell holders! My large family replaces batteries to different devices on a daily basis, so I require a system to store and organize our batteries. I ordered these orange caddies because it was the cheapest color. I also have other colors to differentiate between AA and AAA, and batteries reserved for specific purposes.The caddies can be rather pricey, BUT different colors go on sale fairly often, so wait for a sale to get a really good value.I think I own about fifteen Storacell caddies now and they are all made of thick, quality plastic which are smooth, and very secure. I wish I knew about these years ago! These are a must buy!

It holds all my batteries for my headset. Keeps things look nice and prevents all the batteries from touching each other. Works well and super easy to use.
