Understanding risk? You need to know details about construction, materials, and handling.
Badly made li-ion cells are readily available, and fake wrappers to disguises crap as good ones are cheap too.
I don’t advise other_people to be lucky. How would they follow that advice?
You may feel lucky, that’s your business.
Hey, store it in the glovebox and just don’t drive the car, that will avoid a whole different hazard: vibration:
I’m going to stay away from them the same reason I stay away from ultrafires. However, such batteries are used in Tesla, and they’ve proven to be remarkable vehicles without a disclaimer for ‘do not drive or park in hot places’.
What I notice most so far is that most people are solid with their opinions and have a basis for them which they believe is adequate to justify their actions. What I next notice is a lack of actual evidence of a case of major damage to a car which could be reasonably be believed to have been caused by a LIon and heat. Nothing even close to that. There’s too much of this happening right now for there to not be one reasonably believable case discovered by now.
If this were a legal case in the US under trial, you’d have to prove the damage beyond a reasonable doubt to win- a standard which most of us believe is good and fair. The possibility of damage isn’t enough to carry that case or a jury hearing it. Show your proof if you have it, and don’t argue that there is none on either side if you can’t, because with all the LIon power tools my career-cohorts and I carry there would surely have been at least a few fires by now, yet I’ve heard of none. With so many roughnecks and unenlightened hooligans doing this with apparent safety, then you cannot successfully argue that it is unsafe for us more careful ones without some proof which has at least equal validity in the eyes of a reasonable person. It is not that there is no danger- only a fool would posit that. It is not where the line between safe and unsafe is or how close you’re getting to it. It is certainly not going to apply to those dealing with extremes of heat or poorly made cells. It is only about whether this is safe for most of us. Which I think it is but I also think it’s getting close to that line where safety is lost. How close I can’t say- . Some of us are comfortable here and some are not, that’s all.
I don’t feel lucky, but I do feel safe and if I’m not then please educate me with proof and not preaching so that I can actually be as relatively safe as I feel I am now.
But I have not seen any cases in which one explodes in a flashlight, causing more damage, and destroying a car or killing a person. I also believe the issue is overblown, but I wouldn’t want to store flashlights in a state that they can be damaged because I am too lazy to take it out of a hot car. I don’t think it will hurt me, but it will damage the cell and perhaps make the flashlight unusable, while the items you describe are modular, and the cells are located outside the actual device.
Maybe a lot of people are mistaking caring for their items as worrying their own safety. I don’t think it will hurt me, but it will hurt the cell.
“In a separate incident, an Irish Samsung S3 owner claimed his handset burst into flames as he was driving his car. However, it was later discovered, following tests by the Fire Investigations UK (FIUK) team, that the phone had been previously placed in the microwave to remove water damage and this may have been the cause of the fire.”
OMG, can you imagine the snap-crackle-and-pop that was going on while the phone was being microwaved? :_( :Sp
. . . . .
Okay, let’s add that to our safety guidelines: When drying out any Li-ion cells, do NOT microwave them.
Yes. Like I said a lot of people are likely mistaking caring for their items as worrying their own safety. I don’t think they’re dangerous, but people like to take care of their products.
unless you just wanted to nitpick one poor case, and then retract it when you realized that it does apply, and degrading batteries are indeed dangerous.
