Old pic, but still a valid tip if you use rechargeable batteries. Especially if you travel with them. I keep these in my bag with my camera. When I change out the old for the new, the spent batteries go into the red case until they are charged and can move back to the green case.
All they are is soap containers that you can find most places in the travel section. These were from WalMart.
