If anyone wants to get the plastic organizer cases that are shown in the 2nd post, they are at Walmart (as mentioned) but you need to go the the Fishing Tackle section to find them! I bought two similar ones that are smaller and actually have a handle, sort of like a small attache case.
My son saw them after I had loaded them with batteries and AA/AAA lights, commented to my wife. "Wow, too bad Dad's garage isn't that organized..."
I keep mine in an 18" Black & Decker contractor tool bag/satchel. Started with a 13" model but had to up the size. Time to up the size again I'm afraid!
Check out your local B&D Outlet store. They sell great tool satchels with inside and outside pockets in various sizes for under $10. I always buy one or two when I'm there.
This is originally a 12-to 20-gauge shotgun shell holder. There is just enough tension on the cells to keep them in-place. I added a piece of recycled foam to the lid to prevent any movement.
The liner can be removed, and the case used for P60 module storage - also a nice tension fit.
For AAs and AAAs, some handgun bullet storage cases work well:
I have a few Plano tackle boxes from Walmart for all of my small electronic parts/e-cig atomizers. For larger things like lights I have some "Really Useful Boxes" I bought at Staples
I really want to put a shelf up soon to hold my flashlights.
I have also found that if you can find them cheap enough, poker chip cases are nice storage.
Well I'll be damned, there are times I feel a little slow on the up-take. I've got 8 or 10 of these boxes, in 5 rnd. and 25 rnd. flavors. I was just looking at 18650 battery boxes today!
That's why I offered up the $80 Harbor Freight option. Actually Gerstner is the "gold standard" of tool boxes they have been around over 100 years and last for generations. The USA made boxes start at about $500 and go to over $3000 Gerstner International is the "budget division" made in China but to Gerstner specifications. The advantage of a wooden box is that it inhibits corrosion which is really nice for knives, but may apply to some aluminum flashlights also. The problem for me is I already purchased a lot flashlights and knives and I want a nice format to keep and display them. Call me crazy but is just seems wrong to keep a nicely crafted light or knife in a plastic box.
However, due to the corrosive nature of batteries, it does seem make sense to keep them in a separateplastic box.
