Thanks for posting this, tp. I am quickly developing a zero tolerance for this kind of sh!t. As soon as I read about a vendor selling fakes, they are off my list. So far DD, DX and MF - among the large sellers - have been caught out selling fakes or 'mimics'. Numerous ebay sellers are selling obvious fakes. I will no long buy from them.
Saving a few bucks is no compensation for the damage caused.
Most people don’t realize that those cute little primary CR123A are one of the most dangerous cells made. I would NEVER EVER own a multi-cell CR123A anything!
Did someone say multi-123? I don’t think I am going to keep this light so I didn’t want to buy three 18650s for it.
Send it to me and I will dispose of it for you. 
It’s a sunwayman v60c. Make a reasonable offer an it’s yours. Or, if you have a Zebralight SC80w, we can trade.
I'm not actually interested in purchasing it, currently saving up for a tn30. Thanks for the offer though.
Good info for all thanks texaspyro,just a reminder about how volatile lithium batteries can be.I hope those bat rastards get prosecuted for that,they are knowingly cloning and selling an unsafe product,just to line their pockets...SAD.
It is a FBI report on fake cr123a batteries exploding and the dangers of using counterfeit batteries.
It says policemen sometimes buy orange 16340s off DX and mix depleted cells with new ones and they can go poof. But anything made in America is great….
It doesn’t say that at all. It says that an officer mixed an unauthorized brand known only as “orange” with partially depleted cells and caused an explosion.
The thread title says it all…
Not sure why you were getting an alert… the doc is posted on the Franklin County, PA department of emergency services web site. Some anti-virus software these days is so paranoid, it says your mother is infected with digi-cooties.
Also, I could not post any extracts from the document because it is locked against editing, copy and paste, etc.
I read it so that some officers just don't care about battery safety, mixing different (brand / charge state / ...) cells => sometimes things go *poof*.
If I would be using primaries in multi cell light, I would be very careful what brand to use. You can always test the initial voltage, but if two individual cells have different capacity... Bad things can happen.
You can always test & match rechargeables, so "any" brand is ok as long as it tests with same initial voltage & capacity.
I thought that’s what I said…
I wonder why these “officers” don’t use rechargeables in the first place.
Only exploding flashlight case I heard about in real life (not from internet) included CR123A batts.
In fact, the guy wasxnt sure were this primaries or rechargables, because he charged them n charger.
And than, at night, when “charging” finished”, he went to his bathroom (not to wake his wife) to try the flashlight, to try weather the cells are full - and kaboom!!
Reflector exploded to the front, he said the tube was hot half and hour later.
But Im really not clear did he charged lithium primaries, or that were really Li-ions in question. He doesnt know it either.
I think there will be more expplosions because people dont know nothing about multiple cell flashlight configurations, and more and more people buy them from ebay and other places, with pretty crappy cells.
Before a month or two one older guy came to me with tiablo A9 collimator, saying that his flashlight wont work. One batt was fully charged (unprotected 16340), other was under 3,0V. He didnt had a clue about that or what it can do
I think the good thing was that he obviously kept the switch in off position.
When I sell a flashlight with Li-ion cells to anybody, I give them written instructions on one A4 paper 
Including instruction that, if flashlight for any reason stops working, to remove the tailcap.
No, you said they were buying rechargeable 16340s off of DealExtreme.com. The article says nothing of the sort. Simply that the batteries were “unauthorized” and were known only as “orange”.
I have a Hugsby S3 mounted to my Ruger Mini 30. I love this light it has a hard driven P-60 XRE drop in with an aspherical lens that will throw a beam 300 yards that’s clearly visible through my Nikon 3-90x40 scope in the pitch dark. The three CR123s it required freaked me out after doing some research so I switched it to two 17670s and I recharge them about every 3 months just to be safe.
Unfortunately , User Error! User Error! and more User Error !
People become complacent , thinking CR123A is safe …
My brother is in this boat ! , he just gave away his 18650 batteries and his 2 x 18650 XM-L flood to throw [ which he likes very much ] cos he thinks 18650 takes too much maintenance and that there potentially dangerous .
Yet for some reason thinks CR123A is safe [ go figure ] …
He is swapping to AA only lights [ good for him ] and I plan on picking up a 3xAA in XM-L or doing a XM-L mod on a 3xAA host and giving it to him at Christmas .
Problem is those AA and AAA batteries , being some what safe [ till they leak ] and not really exploding like a pipe bomb has given the general public a sense of complacency , not everything is safe . Some times users need to use common sense [ not so common ] , and educate themselves about the technology they wish to utilize . [ another thing possibly lacking - education ] .
Dont want your flashlight to explode ? Stick to single cell lights ….
