Use for "used" 123A's?

Use for \"used\" 123A\'s?

I gather there's still a bunch of energy left in these 123A's even after they've been "exhausted" in a SureFire.

Any good LED uses for them to get that last little bit of juice out?

Re: Use for

Mike,

Maybe a SureFire E1e/KL1 combo or SureFire E2e/KL1 combo would be good for this purpose. The E2e/KL1 combo would work better since you're using two 123s together.

And then after that, you can buy the Surefire 3 lumen battery pack light. /ubbthreads/images/graemlins/grin.gif

Re: Use for

Seems like mixed reviews on the KL1.

I do have 2xE1's, E1e, E2 & E2e though -- seems like I should convert SOMETHING to LED!

Re: Use for

The KL1 is a fine, well made, fairly bright conversion on an E2 or E2e. It is not severely overdriven, the color of mine (#A00533) is a touch violet compared to my Q3's, but outside you don't notice it. I paid $27 used, well worth the price. Runtime is excellent - near 4 hours on 2x123. I have brighter lights, but there's something about a Surefire......

I gave the KL1 a five star rating on my website, but I don't know how well it will do on pooped out CR123 cells.

If you're SURE they're pooped out you can put two of them in a UBH with one dummy cell and power an Arc LSx for hours.

DO NOT POWER YOUR ARC WITH TWO FRESH 123As!!!!
POOF!!!!

I find that a non-regulated led light such as X5 can use those spent 123 better than regulated one.

I had a pair of spent 123. I tried one in ARC LS, it doesn't light up at all. I put them in a X5 and it does light up.

If you want to squeeze the weak 123's further use 3 in a UBH with a KL1 or three in a 9P body with a KL2.

When I'm in the use-up mode, I check the cells on an old analog battery tester under a 160 mA load. When the 3V 123 shows up as equivalent to a weak alkaline AA cell its time to toss it.

I really got a kick when a formerly very active member, SurefireM6, aka Yoshi Yamamoto solved the problem by selling 55 of his used 123's on BST.

I was thinking of using my x5t to use up my Used batts out of my Arc LSH-P....
But...GJW.... that is a GREAT idea!
I was wanting to get a 2x123 mcluck lail for my Arc grey kit anyway. I think ill use it on my LSH-P with 2 real low 123's. /ubbthreads/images/graemlins/thumbsup.gif

What's a UBH?

I use a Rev 1 Arc LS (the one that had the 1xAA pack) I get very bright light for over half an hour. The old Arc LS is great for sucking those 123's and AA's dry.

"Dead" 123s would be great for lighting 5mm LEDs for hours!!!

After my E2 dies, I put the batts in my X5.

Used 123s have no use in my book, I keep them in case of extreme emergencies that I need all the power I can get. To me, I hate the feeling of having a super bright light and NOT have it operating at full brightness.Its like having a detuned sports car. Then I also think, what if I am in an emergency, and what I have in there is the dead battery?

Well, we can always send them to Maglights as a reminder that the more innovative and creative light manufacturers use them extensively in their lights.

think pretty much any 2x123 DD light can use them--been running mine in this slight distortion of a Dorcy Spyder:
