Does anyone EDC batteries on body? In your pants pockets or what not is what I'm asking. I don't really want to containerize anything else for on-body carry (I'm wondering if I've got too much now) but I feel somewhat exposed because right now I don't carry any extra batteries. Would vacuum packing batteries work? Keep the moisture off of them and keep them from contacting each other. Or are there considerations I've missed?

Do you carry just enough to reload the EDC tools you carry, or more? Remember, I'm thinking on-body. I use AA and AAA mostly.

Thoughts?
