Such a cheap and easy way to ensure safe storage of your spares. I always worry about throwing batts in a pack with the buttons and tailcaps exposed. They could easily short out on objects. And the worry is not so much fear of fire, but the batts getting drained. Even if they only drain 25-50%, thats still significant loss of runtime in your light. Plus the case offers protection from water/moisture, especially if something spills on or in your pack. Get several so you can stash them in different locations

If you are prepared and always carry extra batteries, these cases make it easy and simple. Always have these on hand!

Highly Recommended and super sturdy!

Great fitment and quality.

The battery cases are well made and secure batteries safely especially needed for travel.
