18650 Battery Storage Case Plastic Waterproof Battery Holder for 18650 and 16340 Batteries (4 Pack)

Aw man. These work really well ! Perfect ! Easy to use, just snap 'em shut ! Compatible with 18650 batteries. They keep them dry and safe from shorting out. Wonderful !

They do lock, they are waterproof, they make a little noise. They are great for traveling and cheap. You could also put jewelry in them or anything else that you need waterproof. Rgross

I got these to hold my vape batteries. These cases are very strong and snap shut really good. They hold 18650's pretty well. They do however run a little long for them but it's not a problem at all. Good deal

I got these to store and carry my 18650 batteries safely. I like that the lid snaps on securely with the little wings on each side of the lid. The boxes seem robust. The are much nicer than the typical hinged thin plastic cases which came with my batteries. I'm not at all worried that these will inadvertently come open inside a carry bag or coat pocket. I do find that 18650 sized batteries rattle around a bit inside the boxes—mainly in the lengthwise direction—but I can live with it. Overall a good product at a reasonable price, and I am pleased with the purchase.

Great battery cases for 123 batteries and 18650 batteries. Pretexts those lithium from touching

Batteries fit great. 1 case will hold 2 18650 button top batteries and have a plastic divider in the center which keeps them from touching each other. Snaps close very tight, and secure. Will keep your batteries safe. Good quality. Much better than I expected. Great purchase.

This is the best inexpensive, waterproof case I have found for the Streamlight SL-B26 usb-c rechargeable batteries. Fits 2 batteries. There’s a little bit of a rattle from the batteries but is easily solved with a small piece of foam or cardboard if that bothers you.

Very happy with these cases. Where have they been all my vaping life
