Where do you keep your batteries?

I have five batteries for my E-M5 ii, and needed something to contain them in an order that they can be fully used. What I mean is that, if I label them from 1 to 5, and re-charge any of them once it runs out of battery, I need to place them in order so that each of them is used once if I change and charge 5 times. For example, I used battery no. 1 and charged it, I want to make sure the next one I picked is from no. 2 to no. 5, and no. 1 is used after no. 2-5 all have been used.

I'm thinking of buying some metal gift box with just the right dimension and depth (to have at least 5 batteries stacked in it), I'd prefer it to open on either side (like a tube) so I can pick a battery from one side, use it, then charge and push it to the other side. But is there any other suggestions?

Thanks in advance and sorry for my text if it's misleading.
