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.
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…)
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 )
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
