Thanks to; CouldUseALight, Pöbel, JetskiMark I make this list.

They FIT in the following lights: :thumbsup:

Armytek Predator
Jetbeam M1X
Spark ST6-460NW - The cell slides in and out easily, but not by gravity alone. The length is fine.
Ultrafire C1 and 501
SolarForce L2N host
SolarForce L2P (at least in mine)
SolarForce L2P (older, about 2 years prob)
SolarForce m8
SolarForce L2
Old style L2 with extender and MPP-1 head, though it didn't drop in full speed due to air cushion so it's a tight fit.
Sky Ray King
TN31 (very tight fit tho)
Fenix TK75
Sunwayman C20C "Tomahawk"
Shiningbeam Blaze
Nitecore P25 TM26
Paladin i6
Keygos KE-5
SkyRay King
Sipik SK98 flashlight
EagleTac G25C2 Mark II XM-L2
Niwalker BK FA-02 (MT-G2). Since the battery holder is the same in the BK FA-01, I'd say they fit OK there too.
K40 from Vinh
Shadow SL3

Tight Fit for
Eye 15
Fenix TK35
Niteye MSC20
Eagletac D25LC2, if I loosen the tailcap a bit.

They FIT in the following chargers:

- Nitecore Intellicharger I2
- Nitecore Intellicharger I4 V2
- Miller ML102
- Soshine SC-S7
- TrustFire TR-003P4
- UltraFire WF-188
- Xtar SP2
- Xtar VP1
- Fenix ARE-C1
- Xtar WP6 (not mine) vipsmps


They DO NOT FIT in the lights below::thumbsdow

ZebraLight sc600 (too fat)
TM15 (too tall, but does work if you tighten the head like hell, not rec'd)
ElektroLumens SAR (too fat!)
FireFoxes3 (too tall AND too fat!)
Zebralight H60
SD6
H600w
ST360-CW
Cannot Fit / Too tight (fat) (but can force in and have hard time to take it out) for
Fenix E50 (Single / Double Cell). Double cell will crash the -ve end of the battery
DQG tiny V1 18650

They DO NOT FIT in the chargers

- UltraFire WF-139

in the "USB power bank" (2*18650) that I got from eBay.(It's the white one with a slide-in design and an orange "ULTRACELL Plus+ Smart Portable Charger" sticker, although it is sold with other names/stickers as well.)

As for Fenix PD32UE, as mentioned by other forumer, it is cause by the -ve plate is a bit raised as per pic below (right). To make it work (initially), I put a round donut ring tape (got it from notebook battery pack) at the bottom of the battery as per pic below (left). Then it will work.

But, due to limited quantity of the donut ring tape, I put it at the tail cap - spring area as pic (right). Left is the original without donut ring tape.
By doing so, I can use all 6 batteries in PD32UE.

I think that whoever installs the PCB should remove the original packaging of the battery to make them a little thin, but this way is left to show the originality of the battery

I will make some current test in a couples of days

Curious on this one. The measurements abode show this at a hair under 70mm. Nitecores 18650 are listed at 70mm so I would have thought these would fit as the Nitecores fit in the TM15. Is it the shape of the button that makes them not fit?

Well good for you, congrats and keep up the good work. I tried combining the two(e-cigs) ...didn't like it much.

i gave up smoking standard cigs and started making my own roll ups .... therefore freeing up more money for flashlights and batteries/chargers !!!! :) :) :)

Is amazing what we do just for have more money to buy lights and batts

After all we are very active members of a forum that has the word candlepower in it and our status here is depicted as *flashaholics*
That in itself is befuddling to the average member of society.
Nothing really surprises me anymore here
Ha
This place is great

I have the Panasonic 70mm too. This is my observation: In in light with front and rear springs, if I push the cell inside the tube and it does not go in deep enough (about 5mm), like in my ZLSC600, XT11, the springs will bottom out, the tail cap can't be screwed tight, therefore no light. . But in my other 1x18650 light, like the Xeno G42, pushing it inside the cell tube you can see it goes deep enough to accommodate it. Be careful, some lights are in the border-line (like the Lumintop T5), it can accommodate it but crushes the button in a little. No problem with K40 batt carrier.

Just received my 3400's and they fit my TN31 very snugly , and they also fit my Catapult with no room to spare. No rattle in these lights. I just ordered 3 more pair.
