Protective Battery Storage Case for 18650 16340 RCR123A Batteries, Pack of 4

These are great, simple, cover the contacts and take up almost no space. They probably don't provide as much protection as a hard battery case, but for just slipping into a pack etc. they are super.

After ordering hundreds of products on Amazon, this is my first review! Awesome awesome awesome! These are exactly what I needed to keep extra 18650's in my pocket, bag and in the car! Please let me know if someone makes these in AA size as well. I ordered 4 sets and they quickly sent me five sets!

Product is exactly what I was looking for. Good for pocket carry. Super fast shipping, even if it is a tad pricey. On the other hand, I ordered six, and they threw in a few extras!

Great product. Great price. Fast shipping. Hold and protect 18650 batteries perfectly. I use a bread tie in the lanyard hole to indicate drained batteries. Ordered two and got a third thrown in for free. Super happy with purchase.

These things work great. The battery fits very snugly and I no longer have to worry about an 18650 shorting out in my pocket!

Great battery covers. I would order them again and they were at a great price!

Great little cases. Ordered 2 sets they sent me an extra one. Awesome!

Perfect! I usually only carry 1 extra so the large plastic two-battery container was getting annoying with the rattling and stuff, these are much better. They make safely carrying an extra battery a breeze!
