EDC Battery idea w/pics

[Pydpiper]

I wanted to have a way to keep a set of batteries with me without taking up extra space and to remain water resistant at the same time.
I Used a piece of schrink tube, made 3 plastic washers for each end of the batteries, insert a cord for neck use or with a keychain or whatever and with great caution heat the tube to a snug fit. Awesome results.

Ok, got it..

To get the cells out just snap it in two.. Completely disposable, even the shoe lace. /ubbthreads/images/graemlins/wink.gif

Great idea!

If those are CR123's, you can strip the label thingy off of it and use a heat shrink tube to suck two of them together to make a single drop in battery.

Its not really related to your idea except for the shrink tubing part. It needs to be thin tubing too.

This shrink tube is heavy, waterproof and has a "bonding surface inside, just happend to be the ones I grabbed.

Update..
This has proven to be an excellent way to carry spares, I made a few and left them around in places like my glovebox, dresser drawer and my pocket. It is the same size as the batteries themselves plus a bunch of protection. I have made minor modifications that allows the pack to be waterproof as well, I even made one for my keychain.

With the bonding stuff inside the tubing, does it stick to the batteries? Is it heat activated?

 

[Pydpiper]

The bonding stuff inside is a heat activated layer, it is quite thick.
This has to get very hot to begin the process of "becoming sticky". I heated the whole tube till it was snug around the batteries, then with a lighter sealed the ends. I would not choose this type of shrink tube if you plan on getting at the batteries in a hurry, tonight my torch quit while I was laying in an attic with an angry squirrel.
Regular shrink tube would break fairly easily but not be water resistant, this stuff forms a rubberized skin around the cells.
No, the glue did not stick to the batteries.
