In my closet there is a bin full of batteries. This bin has no internal organization; all different types of batteries are jumbled together. You could say that I have just hidden the mess, and that there is no point having a battery bin unless you are also going to have a sub-bin for each type of battery - but in practice, this is enough. When I need a battery, I know where to look for it, and there are no batteries cluttering up any other parts of my house.
