What are you guys doing for "long term" battery storage? I've been rearranging some things lately and am revisiting my half ass battery storage. Currently I'm using some random tupperware pilfered from the kitchen, basically a couple of these:
I have one full to the brim just like this that works fine, and this one is often scavenged for kids toys, etc. Point is as soon as you pull out a couple batteries the whole thing goes to crap and everything gets jumbled. I'd like a better option that can keep things organized but accessible.
Also curious if there's any benefit to storing open vs. airtight.
