What to do with 50x CR123s?

LED Flashlights – General Info CR123A Flashlights
1

A couple years ago in my early flashaholic days, one day I decided to have a supply of CR123s, in case of “something happened”. I spent more than $100 buying about 70 pcs of panasonic and sanyo CR123 primaries.

Well, “something” never happened and somehow now I have a stash of 18650 instead which are far more useful. However my CR123 are about to expire in 3 years and I don’t know how to use them. I have about 50 left, and my only flashlight that takes them is a nitecore extreme infinity (only 200lumens).

I would like to mod a cheap light and make it CR123 compatible while being bright enough for me to EDC. Any suggestions?

Sell them here or on ebay.

But keep 5 - in case that “something” happens :wink:

I have a groovy idea. Give them away to some new Flashaholics. IMHO: You have already gotten your moneys worth. You used 20, the other 50 made you feel safe and secure!

Share the love, open a giveaway thread that has say….5 winners…to qualify they post a pic of their CR123 light and they can’t have, say, over 100 posts or so.

There ya go little fella, problem solved, love shared, good feeling in your heart & mind.

In the famous words of the RHCP: “Give it away now!”

I would buy a few single cr123 lights and use/keep them .They aren't going to "go bad". They don't take up much room.

I have some old Romisen lights that run well off these in my cars so I store about 2 lights and several batteries in each.

you could modify your flashlight(The ones work with 18650 battery) by changing the flashlight bulb.Usually the flashlight working with 1 x 18650 battery has the working voltage 3.6-4.2V. If you could replace a bulb with working voltage more than 6V, then your flashlight could work with both 18650 and CR123A batteries, but the working tube could be installed 1 x 18650 or 2 x CR123A batteries. Actually most flashlights’ tube could. :smiley: Hope this could help you out.

Where do you live by the way? If in any chance you
Are near me (i live near the equator too), i can buy
Them for 20cents each. I think these will still
Work(but lesser capacity) after 10 years. Will be
Making 1 time use flashlights with them.
The giveaway idea is great, shipping maybe an issue though.

I doubt they’ll suddenly die right after their expiration date, so I wouldn’t be too worried about them.

Maybe you can keep half of them (they should be good for another 5-10 years) and donate or sell the rest as others have suggested.

Some long term tests might be cool, maybe test 2-5 a year and see how their performance degrades.

Under $20 and you get another CR123 lol…

The giveaway is a great idea, and I would do that if I was in the US where shipping costs are low. I live in Panama and to ship anything to the US is at least $15. I have several flashlights that I want to sell but can’t because of the shipping costs.

I will do a discharge test with my icharger 106B+ and post the result.

Trustfire Minis looks good! Thanks for the suggestion. the 02 looks like the big version of my beloved lummi RAW.

I noticed Richard just announced a 1-4A buck driver, I think something nice can be built with a S2+.

Also I bought this, looks interesting enough.

The specs doesn’t tell much, but according to one of the reviews it does work with CR123.

15

Sacrifice a few for science and buy a new CR123 light to use the rest in

Extract the lithium sheets from the cell and set the on fire! It’s a beautiful sight to behold.
