Review – CR123 Waterproof Delrin® Battery Locker from CountyComm

If you’ve never been there, has an odd and eclectic mix of goodies that definitely have some merit for those who share our rarefied interests. I’ve never ordered from them before but I finally got around to picking up a few things and thought I’d mention at least one of ‘em here.

From their website:

I dunno about you, but too much of my gear takes the CR123 batteries. Usually these batteries are limited to things like SureFire flashlights and weaponlights, but those are pretty much the high-end pieces of gear that you do not want to have crapping out on you when you need them.

Ideally, I want a battery carrier that is bombproof. Something that keeps things dry, protected, and free from accidental shorting. SureFire makes a Spares Carrier that is quite nice, but a bit bulky for some of my needs. There was, to me, a need for a method to carry just one or two CR123 batts in an absolutely secure manner. So, I ordered up a few of these battery carriers and figured I’d give my impression.

They’re pretty much exactly what I wanted. They are knurled at one end for a solid grip as you grasp the other end and unscrew them. Once open you can see the o-ring in the cap that contributes to the waterproof seal. A CR123 battery fits in there quite nicely with minimal room to rattle. I’ll wind up stuffing a tiny piece of gasket material or something into the bottom of the container to completely eliminate any noise. The cap the container is not captive, so there is a chance you could lose it. There’s a hole in the cap for a lanyard and I’ll wind up putting two of these on a loop of paracord and keeping them with my support gear for my 870, since I got the new SureFire forend for it and want to keep spare batts handy.

Construction is from hard plastic and short of stomping on one they look like they’d hold up quite nicely to the rough-n-tumble of being bounced around in my bag. These things are offered in AAA and AA batt size and I’ll be picking up a few of the AA sized ones as well.

Biggest drawback is that these things are about nine bucks a throw. There just isnt any way a plastic geegaw from a military contract overrun should cost that much. But…if it does what I want then I guess price isn’t worth complaining about.

A very good question to ask would be “Why do you need one of these?”. I don’t know about you, but my bag is loaded with all sortsa gear…lotsa little odds and ends that might come in handy. Things like zip ties, large paper clips (sometimes a small piece of wire is exactly what you need), spare ammo, pocket knives, lanyards, radios, etc, etc, etc. Throw a handful of AA or CR123 batts into that mix and at some point theyre going to contact something and short the case of the CR123, possibly in a conflagatory way. Most of the time I segregate my batteries in the Maxpedition battery carrier (MAXPEDITION VOLTA Battery Pouch). As much as I like the Maxpedition carrier, it isn’t 100% waterproof and airtight. For stuff that is ‘mission critical’ (GPS and radio spring to mind) you absolutely do not want even the slightest chance of having you spare batteries being crapped out when you need them. So, most of the time my spares are in the Maxpedition carrier, but in my little survival kit that I take with me hunting and fishing, the extra batts go in these battery lockers from CC.

Too expensive for all-around use, but for those pieces of gear that absolutely, positively need to have the spare batteries kept in perfect condition these things would be hard to beat.
