Oops.
I obviously misread your earlier post.
So, we have different strategies for acquiring cells and chargers.

I had a 14500 just leak in my GTmicro. No kaboom. No earth-shattering kaboom. Just clear ook leaking out from the beastie.
Mustāve caught it fairly quickly, ācause no permanent staining of the battery-tube or anything, not even the springs or driver.
Does anyone else remember a thread on here years ago of a Skyray King literally exploding?
This guy was using cheap bundled cells, so obviously junk Chinese crap that were unstable
Turned it on for a few minutes on Turbo, heard popping sounds
Turned it off, placed it down and left the room
BOOM!
The shrapnel blew out his apartment window
He had photos of the aftermath. Iāve search in the past for hours and canāt find the thread maybe it was on candlepower
I don't remember seeing photos of the aftermath, so I'm guessing that wasn't on BLF.
I found the thread on candlepower, itās different to what I thought it was, but still an explosion
Ah, I see it was already posted
Just a case of using dangerous batteries though
Dear god! Those look more like grenade fragments
I think i remember that one, lived in an apartment, insurance did cover it iirc.
Interesting theory.
I only use single cell lights, so hopefully that cuts the risk substantially
The proverbial flashlight is between 100 and 4000 lumens (Olight I3e to Convoy M3C).
Yes, If a lithium cell exploded in a flashlight, then indeed it would blow the light apart. It would be a Bad Day.
Most quality cells have over pressure vents that will open if the internal temperature goes up due to any of the various failure scenarios; venting should prevent an explosion.
Thats good.
ShyOne:Yes, a flashlight powered by a LiIon battery ācouldā indeed turn into a pipe bomb.
I DO NOT know the odds of this happeningā¦ BUT, I WOULD THINK THEY ARE EXTREMELY SLIM.
It would be an EXTREMELY RARE occurance.
alpg88:yes it can and it has, there are several thread with pics on cpf, iirc, in one instance, the light destroyed a balcony glass panel, and made the owner bleed. but it is very unlikely scenario, especially if you do not use crappy cells,
I recall reading the post about the incident alpg88 mentioned above.
I have searched for the thread about the incident but cannot find it.It was an eye opener for sureā¦.
HF poisoning :person_facepalming:
I remember a post on cpf many years ago where a guys light,(probably a Surefire) running 2 cr123 started making a whining noise and he pulled it out of itās holster and it was extremely hot. He no sooner set the light down on the counter when it exploded blowing out the end and sending the light flying through the air like a missile where it hit a sliding glass door shattering the glass and putting a huge dent in the frame of the door. So a light might not blow up like a pipe bomb but fly through the air like a missile.
Thats insane.
Funny how i got many mocking replies in this thread for even asking the question.

It's a good thread.
I think some people just don't want to think about the remote chance that lithium ion batteries can be dangerous.
Itās extremely unlikely IF
- You care for your batteries and know all the safety precautions
- Donāt use budget, cheap, old batteries

Yep, it helps to have a safe high quality charger as well.

Ah, yes, I knew I had missed something, but that kind of falls into caring for them correctly

I was just thinking that you and i are old BLFers, back in the old days we were at the basics, while today who knows where the batteries are even coming from, i had to make a thread and ask where Sofirnās included batteries come from (and apparently its not a first tier supplier)
Sofirnās 21700 batteries are now from Lishen which arenāt half bad.
The 26650ās are excellent being from PLB who were used by Shocli.
14500ās are questionable and Iāve received many in the past with rust under the wrap. Reported to Sofirn and was ignored. I purchased in bulk 200+
Not sure what the 18650ās are, but tested okay. No idea on how they age though
Sofirnās 14500 cells with rust

Very interesting.
I try to stick to name brand, My 18650s are Sanyo and Samsung. If i replace them (they are getting close to 10 years old) and get some 21700s as well i plan to go with name brand again. The HF thread is more worrying then the explosion risk.
BTW I actually like your posts becasue as a business you have a lot of experiences none of the rest of us have.
Which reminds me you had mentioned in another thread that Convoy are certified lights, what certification do they have?
Also i noticed CE and ROHS on my new Wurkkos WK30, was surprised to see that.
The brands I sell that have CE, ROHS certs are (I donāt sell anything else yet)
Sofirn
Not the D25S, D25L, S11C since they arenāt made by Sofirn
Wurkkos (Sofirn build them)
Convoy
Guess what, I just found out Astrolux/Mateminco refuse to carry out any testing anymore. Iām ditching the brand. They print CE, ROHS on the flashlights, but have no such testing done at all. I would strongly suggest not buying them IF your country requires these certs for your insurance.
oh and Skilhunt has all the safety certs. I just have their headlamps
Itās extremely unlikely IF
- You care for your batteries and know all the safety precautions
- Donāt use budget, cheap, old batteries
- Donāt be an idiot
That last requirement is why I stick to eneloop.
and get some 21700s as well i plan to go with name brand again.
I did research on 21700s, and I like these the most:
They're very nice, and fairly cheap, but the wrappers on the cells break easily so you have to be careful not to damage the wrappers.

Good to know
How can you tell if a flashlight is tested and they are not just claiming its certified?

Iām all about capacity so i would want some 5000mAh cells.

You have to ask them for the CE certs or whatever it is you need.
