That's a cool system for common batteries. I lean towards AAs, and have adaptors to make them C and D cells. I keep my AAs in a plastic ammo box made by MTM, sized for 500 S+W. CR123s and 18650s go in a smaller Pelican case, while looking for a better solution. Newer higher powered lights are using 26650 or larger, so I don't want to commit to pulling out my pick and pluck foam just yet.
Nice kit buddy, I will stay with my rubbermaid bin in the drawer, I like the guessing game! I only keep my rechargeables separate with the chargers. Generally I am a AAA, AA and 18650 user as well , been eyeballing a 9 volt rechargeable but I just don't seem to use them much.
That's a cool case for standard sized batteries 👍 It's a shame that they couldn't make the 9v slots a bit more smaller to hold them in better. My batteries are AAA, AA & 18650's 😉 Through the years I've gone with plastic cases for them, but no where the capacity of this case. TFS
