While more battery-powered tools and equipment now feature built-in rechargeable batteries, there are still plenty that work with AA, AAA, 9V, CR123, and other types of alkaline, NiMH, and lithium cells.
How do you store extra batteries in your tool box or cabinet? How do you carry them in your tool bag?
You can throw them into your bag willy-nilly or dump them into a ziploc bag and then your tool bag, but both are bad ideas. You could line them up and stash them in a pouch or tool bag pocket, which can work well at times. Securing a couple of batteries together with a rubber band can also work, but there’s a limit as to how many batteries you can do that with. With loosely organized batteries, sometimes you can find them right away, but other times – good luck hunting.
I have been using PowerPax battery holders for years, and I continue to find them highly recommendable. I use them at home for organizing rechargeable NiMH batteries, and on the go for packing and carrying AA or AAA cells. I keep a couple of CR123 batteries in another caddy near my go-to flashlight.
I talked about these battery caddies a few times over the years, starting with this 2011 post, and I will continue to post about them every now and then.
I wouldn’t necessarily call these PowerPax battery holders indispensable, but they sure do make things easier.
They’re especially convenient for storing rechargeable NiMH battery cells, or for carrying depleted alkaline batteries when there’s no place to dispose of them. Fresh batteries can be inserted with the positive terminal facing up, and spent batteries can be inserted with the positive terminal facing down. That way, you can tell at a glance which batteries are fresh, and which need to be recharged or disposed of, depending on the battery chemistry.
These battery caddies are not sealed, and so you still need to protect them from the elements.
Price: $5 and up
There are lots of different sizes and colors available, but I think the 4AA or 6AAA models are a good place to start.
I have a couple of sizes, but not 9V yet. When I need a 9V battery backup, which is rare, I’ll pack it in a tiny pouch meant for camera batteries.
The last I checked, PowerPax battery holders are still made in the USA.
