Delrin® Battery Lockers (Waterproof)

I have always been worried about leaving a loose 3v Li-on battery in my bag. I have seen at their worst what they can do. now, safely in its case I fear no more. Great item and it seems super durable.

Simple, well made and effective!

Anybody who needs to tote batteries should have a battery locker. These delrin containers are terrific. Durable, water resistant, rattle free, they are easy to carry. I own several, in various sizes, and recommend them without reservation.

Using it on a jungle expedition soon so will report if it fails - otherwise, no news is good news.

So far, I have several each of the AAA, AA & 18650 delrin battery lockers. They are very ruggedly made and well machined. They work great for protecting a spare battery or other small items. I just recently purchased 4 of the 18650 lockers and am very happy with them as I have been with the other sizes. I did have to have a slight modification made to them though. The I.D. is 18.78mm which was just a little bit too snug for my particular 18650 batteries. I currently use Nitecore NL1834 3400mAh, another Nitecore 3400mAh used for the TM03 flashlight (not sure of the battery model) and Eastshine E35 3500mAh. All are protected cells and I believe the wrappers may be slightly thicker than some of the other manufacturers. A friend used a lathe to bore them out to 19mm and they work perfectly with all of my 18650s now.

For storing a single battery, this is one of the best. I have no complaints and carry one daily.

I wanted to carry a back-up battery for the EDC flashlight that is always in my pocket. It's a Fenix E13 that is one of my most used buts of pocket kit. I use it many times indoors and out. On a single AA baterry, it gives me 1 hour at 130 Lumens (too bright for most indoor tasks), 3 1/2 hours at 50 Lumens, and 22 hours at 8 Lumens (which sounds puny, but is amazingly useful for close work). The problem with quality LED lights is that they use a smart voltage regulator to give full performance until the battery is almost completely drained. This means they die with little or no warning, so a backup battery is a very good idea. The County Comm Delrin Battery Locker (AA size) works perfectly as it was designed to do. I now have twice the light output that I had, and zero worries about dead battery surprises. The locker holds a AA cell perfectly. There is no side to side battery motion, so no noise when moving me key chain around. I also like that a standard key chain ball fits through the locker's lanyard hole but the key chain connector will not. That make threading keys very easy. This is a quality product, well designed and well made. Also well worth the modest price County Comm charges. A 10 out of 10!

Very good fit with just a tiny amount of movement inside. Excellent way to store battery for protection from water and physical damage.

Works as intended, didn't know I needed these until I found them on CountyComm. I now keep two AAA battery lockers in my pocket with spare batteries for my streamlight flashlight. Couldn't be happier!

I have a Rare 6 from The Knife Connection. I did a build a knife and ordered a Kydex sheath and pouch for the front that holds a Altoids tin. I have a fire - EDC kit which includes a single AAA battery flashlight on the front. So with the black key ring and the AAA battery locker that is waterproof it was a great addition to what I need for a EDC field knife pack.

Tough little case with a perfect fit, which means no rattle of the battery on the inside. The quality is obvious!

For those who don't know, delrin is a high tech plastic that wears like metal. Make this stuff into a light weight, waterproof ( sweatproof ) carry capsule, then you have something for long term EDC.

I've carried the CR123 version for a couple of years, just decided to add an AAA version.

These are the best. Machined out of bar stock and very nicely finished. Get one for each of your spare 18650s.

Finally a perfect container to store the common batteries for illumination devices placed in Pocket Survival kits. Manufacturers of AAA, AA, CR123 often state a shelf life up to ten years, but if you read the fine print, this shelf life is dependent on proper storage. The Delrin capsules provide a water-proof, no contact long term term storage device which we now include in Individual Survival Kits being sold to certain US Military Units. The requirement of a four year shelf life is not an issue when we include this capsule with a spare battery (AAA) in our kits. Well worth the extra cost of a "Made in America" product, and believe me, I have evaluated several from the off-shore knock off junk manufacturers and these were absolute junk. If your life depends on a device to function in an emergency, this is one piece of gear well worth the inclusion in your kit.
