My method is cheap and easy. I get a ranger band ( bicycle inner tube ) cut a piece about an inch wide and slip 7 or 8 batteries in there. Works like a charm.

For some reason I can't get inline pictures so I uploaded it as a file.

I got something similar to these off eBay for organizing my various batteries in my SAR kit:

Hey OBG,

FWIW...keep an eye out in Costco. Our local store now has Kirkland AAA & AA.

Only took about 5 years too long, but better late than never.

I've just ordered some of these case sets, a set of 4 for $2.50 delivered. I'll let you know how they work once they arrive from Hong Kong.

BTW, whoever put up a post with the DealExtreme link it, you're a baaaad person. Now I'm hooked on the darn site... like Costco for tech freaks.

Try the BATUCA cases at InAnyCase.com. These cases fit AAA, AA, CR123's and CR2's. They are set up to differentiate between good and used batteries.

Batuca cases are great, especially for AA and CR123. You can put in AAA's but IMO they're too loose. For home storage the Akro Mills clear storage dividers work really well. Small but maybe important detail, the plastic dividers are all rounded and smooth so when you pull out a battery it doesn't cut up your fingers like the Plano and other clear cases do.

Used to take scrap lumber and drill a row of holes, glue on a cap over the holes and rip it about 3/4 the way up. Pretty handy for AAs, AAAs and CR123s. A bit bulky but still good for Cs. Less good for Ds.

Ten AAs fit in a 10" length of 5/4. They keep the batteries entirely separate and well protected. Once made you can screw the unit to any vertical surface, I used to have a set screwed to the inside of my truck box, and they can also be used as carriers.

You can rig a latch or simply wrap a bit of inner tube around the units to keep the top on. Mounted vertically the tops stay put as long as there are a couple of batteries inside.

I bought mine of off of County.com for my AA's they work great.

I kind of like the looks of this one. Might be able to sort--charged ones on top, depleted ones on bottom...

I just took my son shooting today. I have a 1931 Mexican Mauser chambered in 7x57. We used Federal "Blue Box" ammunition. When I came home I thought I would try to see if an AAA or AA battery would fit in the shell holder from the box. The AA didn't fit at all. The larger hole for the cartridge body is too large for the AAA. But, the smaller one that the bullet/projectile goes in holds the AAA very snugly. I could cut away what isn't needed. Since my camera went on the fritz I'm afraid I can't post a picture.
