16670 (exact 2xCR123A size) Li-Ion cell?

WildChild · Aug 26, 2007

Does a 16670 Li-Ion (exact 2xCR123A size) exists? This would solve the problem with some flashlight that need to be bored so the 17670 would fit. It would probably have a slightly lower capacity than a 17670 but probably a greater Wh capacity than two RCR123A. What do you think?

no such cell exsists, AW has some 14670s that will fit place of just about any 2xCR123 config though

Fast forward from 2007 to 2012, and lo and behold, I stumbled across a Sanyo 16670 li-ion cell, in Japan. At the moment it appears these specialized cells are available only in Japan or China, and apparently only in minimum orders of 100 or thereabouts, so it's not likely that we'll be seeing these offered for sale at North American battery merchants' websites any time soon.

Nevertheless, regardless of the application these cells are intended for, I want some.

I did test 16650 batteries.

Also worth noting is the suppliers that say they have these and sell in bulk, do not have them. And the ones selling them individually are selling pre-production sample / reject cells from about 2 years ago.

Scored some 16650s from an Acer notebook battery salvage. Best was about 2000ma, worst was 1800ma . These were orange wrapped w/ green tops.

Yea let us know the battery pack model. And secondly thats kind of odd they are orange... I've only seen them with Red heatsrink. Lastly, your capacity tests were they done with a 4.2 or 4.3v charge voltage?

Charged @ 4.2v. Sorry can't give you the model as the swarf was tossed in January. I have 4 to spare, anyone have something to trade?

doh! I've been dying to know what model laptop it came from. You can't ask someone and find out?

Secondly, you should probably post trade type stuff on CPFMP.

While on the RCR123 compatible topic... Does anybody know if someone makes something like a 16500? for use in RCR123 lights with AA extenders? As far as i have found the 14500s and the RCR123s have about the same capacity (~750mh) so I don't really see a reason to use the longer 14500s if it doesn't really benefit you (unless I'm missing something... which I probably am).

Think they came from "Dumster Diving" a Best Buy recycle bin. I do remember it was an Acer pack and mfg date <2yrs. Unless I need a specific size/chemistry (lifepo4) or such, I don't buy ICR or IMR 18650s.

Why is it that whenever people find OEM 17670 or 16650 or 14500, they never say where they found it? That's what pissed me off so much, I searched for several years, finally just gave in and had my surefire bored.

RedForest UK · Apr 18, 2012

Iintl-outdoor have the sanyo red wrap 16650s, were those ever conclusively shown to be from a reject batch?

I am waiting for 8 of them from this place here -> http://www.fasttech.com/product/1210700

bshanahan14rulz · Aug 13, 2013

Those look fairly old, but please do let us know how it goes! I was mainly talking about, say, "Oh, I found 6 of these in an HP H530x laptop" or something like that.

I will keep you in touch -> the voltage at arrival, the packaging and my own picture of these cells.

CampingMaster · Aug 29, 2013

I received them today, very well wrapped but not in the carrying case as they say here -> http://www.fasttech.com/product/1210700-as-is-sanyo-ur16650zt-1665017670-2100mah-37v-recha

As you can see the + side is a flat top...

The - side.

The lenght is much less thant two CR123A.

Here is the big problem... The + side does'nt contact with the head of my Quark Pro QP2L-X gen 2 flashlight.

The two half moon that you see each side of the center contact are higher than the center contact, then the Sanyo 16650 rest on the two half moon and the center of the cell ( the recessed + side ) does'nt contact with the center of the head. Which means that these 8 cells are useless for my Turbo X and my Quark Pro. I don't know how come few people in the forum say that they are using these in their Quarks because they can not use 18650 cells - it does'nt work for me. I lost 35.40$USD because I read in this forum that this a good choice for Quark's Flashlights. If somebody around Montreal wants them they are for sale at 30$ ( 6 cells are still wrapped ). Thank you for any input to help me :-(

There are magnets you can use on the top of the cell to extend the length. They are cheap. Look online. Don't sell them! HOWEVER. I DON'T KNOW HOW WELL THEY CONDUCT ELECTRICITY AT HIGHER CURRENT DRAWS.... Mabey some one can add to that.

climberkid · Aug 29, 2013

That still sucks that they don't actually work. Did you get the measurement of the cell yourself?

16670 (exact 2xCR123A size) Li-Ion cell?
