Goodness. From that article it would appear he leaned in over the radiator or from the side and maybe grounded out the positive terminal of the car’s battery with the flashlight, causing the light to explode. His face,neck and upper body would have been exposed to the explosion. Sounds like a horrible way to go…

I do it all the time. Maybe should stop.

Very unfortunate circumstances, those.

poor guy. I lean into the engine bay with my flashlight all the time, thank god my battery is in the trunk and there are no exposed contacts. Still, need to wear headlamp at all times now.

Wow pretty disturbing. It’s really not clear what happened. If the flashlight shorted the car battery like Dale supposed the flashlight might heat up enough to send the cells into thermal runaway, but this seems unlikely. I wonder if it was a pre existing condition with the light (bad CR123 cells in series or something) or if the article was wrong and it was unrelated to the light (something in the car blew up and they thought it was the flashlight).

You know, that’s a possibility…

Sigh… poor man…
Well, that’s the reason I don’t want lithium batteries on my head.
By the way, this isn’t first time that flashlight was put in the mouth and exploded…

Every day millions if not billions of people hold lithium batteries to there faces by using there phones i dont think its such an issue if engineered well.

Al thought this is not the first case after a quick google search its happen a few times.

This is an older case with pics of the light in the article.

It’s a Solarforce L2T in the picture.

The article doesn’t say anything about the man putting the light in his mouth, nor does it say anything about whether or not it was a Li-ion flashlight. It was said that when he leaned down into the engine compartment his flashlight exploded. So I was assuming the flashlight grounded the positive battery terminal.

Phones aren’t good for holding the pressure – in most cases I can throw it away if I feel phone burning. Also, typically phones are held far enough from most sensitive parts (eyes, mouth…)

Those batteries look to have been 123A type IN SERIES….danger Will Robinson ! Those have been indicated as potentially dangerous before.

And what is the possibility he could have had RCR123’s installed???? And In Series ! Shocked

Not enough info.

Yep, there are these things called headlamps!

Headlamps, sure… perhaps an explosion near the frontal lobe does less damage.

Odd coincidence that the OP’s name has something to do with death and mortality…

12 volt through a 3v or 4.2v battery , yep !
Thats pretty much how they make Li-ion / LIPO go boom ..
From serious over volting ..

Check out youtube , I saw one where the guy tried and tried to make lipo fire and failed … Only succeeding when seriously over volting the battery .. Reverse polarity short is ?? , over volting is pretty much a sure thing . ( A lot of extra volts – not just a little ) The boom ! Lipo fire can be nothing , or it can be magic smoke , or flame and smoke , or a small bang and flame or it can be a pipe bomb .. It’s just the luck of the draw , and if 12 volts got jammed through those batteries , ?? it could have been a pipe bomb . ( Those nasty variables )

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Guess the skull protects a little…. I would be concerned about eyes though.

Lithium batteries in series are always dangerous if one of them depleted earlier than others. It heat up very fast as i encountered this a few times for both rechargeable and non rechargeable, bad quality one will explode i guess.

No problem. I had one time used two genuine Energizer AA lithium bought at local shop like Watson or Guardian, some how one of them depleted earlier and i suddenly felt flashlight battery tube was getting hot. I quickly switched it off and measured the voltage of them, one was like 0v. It is confirmed by my own experiences it’s not safe to give lithium batteries to common flashlight user. I think i made this mistake when i gave my family some AA flashlight thinking AA is safe. Now i give them USB rechargeable flashlight only.

I wonder if was the car battery exploding and the torch is unrelated or maybe the torch only caused a short or his watch or something else on or near the car battery that might have ignited the hydrogen gas.

Find it hard to see a torch that someone could fit in their mouth would have the power to kill them, but could see a large lead acid battery exploding close to someones face or head having enough power to cause serious injuries or maybe even killing them

I don’t understand why people still use 2 CR123 instead of a single 18650?

I think most people don’t think about risks that are relatively rare and that has never happened to them. Look at all the people who buy reloads at gun shows from people they’ve never seen before who may or may not know what they’re doing. And high pressure rifle rounds that let go right next to your face can do a lot more damage than any flashlight battery that vents/etc.
