Great product I have multiple of these cases I keep them in multiple gear bags that may find themselves in austere environments.

I have 3 of these cases now. Getting ready to buy another couple after harvesting some more 18650s. I night hike quite a bit with a couple of different Fenix headlamps that run 18650s so one of these rides in my backpack 24/7 and I don't have to worry about my backup batteries getting wet, dirty, damaged or shorting out on something. Fits both my protected and flattops perfectly. Wish the foam insert came permanently attached but I can fix that myself.

I have 6 of these now. They're thick and durable, but light and compact. Well sized for a cupholder, saddle pocket or backpack pocket. I haven't tested, but I'm very confident in water resistance and shock response. These have made a lot of night adventures very fluid, and extended work shifts easier. Every Mecarmy product I own has been worth its price 10x over.

This case is built solidly and seals tightly. You can't stack it like you can the flat rectangular cases, but it would be fine for dropping in a backpack.
18650 battery case
December 2, 2020
Holds six 18650 batteries securely. Comes with a fitted foam insert under the cap. It's loose when there are no batteries but when the batteries are loaded, prevents them from moving thus creates a solid and stable housing. Fits all kinds of 18650s; protected or not. The plastic of the case is smoked so you can see the batteries inside. The case also comes with a lubed O-ring so the case should be waterproof. Overall, a great case for the adventurer who needs a dependable, durable, weatherproof case for batteries.

Works well for the intended purpose and more.

These are a secure way to carry your 18650 batteries. It will also hold various other items as well. It is weatherproof/waterproof enough for almost any use other than completely submerging it deep for a long period of time. It has never failed me in any way so far. If you have an extra conversion sleeve for CR123 sized batteries for your 18650 light, they will fit in here also, along with a small USB charging cord, etc. The top foam padding is not secured in the lid and can fall out, but is easily remedied with a small piece of double sided tape. A good product, and I recommend it.

These are great, I can't wait to try 21700s in them! If they fit, looks pretty close.

Almost identical to similar Surefire CR1233 battery case (Very high quality) except for 18650. Very happy with purchase.

A Very Handy Case

This a nice case for storing my rechargeable 18650 batteries. I like the foam in the lid. I also used the pluck foam from my CR123A battery case, which I cut in half for shock proofing the bottom of battery case. I will buy another soon.

Works as it should. Batteries fit good and the case protects them well.
GREAT BATTERY CASE!

I LOVE THESE CASES! I HAVE A FENIX LANTERN WHICH TAKES 3 18650s AND NOW I FILL THIS UP AND HAVE LIGHT FOR A LONG TIME! I CAN PUT THE USED BATTERIES UP SO I KNOW THEY NEED TO BE CHARGED. PERFECT FOR MY NEEDS! I HIGHLY RECOMMEND THESE STURDY SMALL CASES

Battery case was what was expected. It did come with foam for the top of the batteries in the case so they wouldn’t move, but it would be better if it had a similar piece of foam for the bottom to also protect from shock if dropped. All in all a good case that seals tightly

this is a very handy case for travel or hunting to keep your 18650 batteries handy and secure. Very good price also. Well made and sturdy.

Overall, not bad

I bought this battery case to hold my 18650 vape batteries. I have eight of them, and my vape takes two at a time, so a case for 6 was perfect. I liked that it wasn't the standard "clamshell" style case. The screw-on lid is very sturdy and (in my limited experience) dust- and water-resistant enough. My only problem was that the threads on the cap were WAY too tight--it was challenging to get it on and off. I thought it was stuck shut the first time I tried to take it off! I fixed this by rubbing down the interior and exterior threads with some coarse-grit sandpaper for a few minutes; now it goes on and off smoothly. For the price, that little bit of work was no trouble for me.
MecArmy B18 Battery Case

great battery case to keep your 18650 batts protected (and to protect against shorting/fire risk). Case is water proof and seems durable. Great deal for less than $8

Holds 6 batteries in a small space. I like that I can put the batteries button up for charged, button down for discharged. No guessing which ones are good or which are dead.
Great Case For a Great Price

There aren't many water and dust-proof cases for 18650 cells. This one is of the highest quality. The seal seems very good, and the cap screws on easily, yet firmly. This battery case will be a vital component among my emergency supplies. I'm grateful to have it, and I think it is a bargain for this price.
