This is going to be a great help and ease the mind. As we all know, batteries are inherently dangerous. They can overheat and possibly explode should they be shorted or fail internally. They will explode if in a fire. Dangerous, but a part of everyday life anyway.
This case provides good protection. It is waterproof, fire-proof, and explosion-proof. It organizes more than 200 assorted batteries safely. It also includes a battery tester.
