I found a really neat way to organize my batteries other than my pelican case method. We have these for sale on our LightwareDirect site. They are inexpensive and easy to keep in your camera bag or case. Plus they take up a lot less room than the Pelican case. They can be put in either way to signify used or unused (if they are rechargeable). Hope you find them helpful, I certainly have.
