Itinifni, I just realized your name is Infiniti spelled backwards

You got me, but they’re not the parent company. That would be Nassin, or when I started (here in the states) Nustad. :bigsmile:

I remember a time, when I searched for lights to fit my needs. Now I search for needs to fit my lights.

I don’t store flashlights with li-ion in my car, but my dashcam has a li-ion battery and the temp in my car often goes over 120F (50C).

How does one go about determining the root cause of a pile of slag? What percentage of vehicular combustion events get investigated? Just curious since many are asking for proof of danger where it seems to me it should be a question of proof of safety. I agree that there’s a distinct lack of evidence but as the saying goes “absence of proof is not proof of absence”. A vehicle in the northeast might hit 130 and one in southwest 160. I feel less at risk living closer to the coast and the more moderate climate than I would living further inland.

What does it take to cause thermal venting in a vehicle and under what circumstances can venting bring about ignition?

Answering those two questions would settle this for me.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

The CDC says the interior of your car can reach 172f.

Not what we have but what we enjoy, constitutes our abundance.

Thanks, ltinifni. Common sense prevails. Lacking sufficient controlled experimental results your anecdotal reports are the next best thing, and really helpful. We continue to have these cells in our vehicles, but still exercising a modicum of caution.

The question isn’t what the battery manufacturer’s recommend. The question is how well documented their concerns are?

If this discussion thread is any indication, then the answer is, “very little.” H)

In the US companies warn against everything they can think of. I have jack stands that warn against getting under the car when the jack stands are being used. I expect battery companies to be the same…if there’s a .00001 chance of something happening then they’ll warn against it.

Those battery warnings got me thinking, a quick check of the “Important Safety Warnings” of my old Magellan manual says:

“Keep the Magellan Maestro safe from extreme temperature conditions. For example, do not leave it exposed to direct sunlight for an extended period of time.”

Interesting…

So basically every Tesla is a rolling time bomb that can only be driven in 50-75 degree weather under cloudy, but dry skies and must only be parked in a climate controlled, waterproof, air sealed pressure containment housing that can absorb the inevitable explosion if any of the conditions of the warnings are ever exceeded. Got it!

I imagine that the tesla batteries never reach the temperatures that car interiors reach when they are sitting in the sun (170F/80C).

Most of the pushback against li-ion cautions is from the tobacco industry, which in China is a government monopoly.
They’re rushing to cash in on the vaporizers. Kickstart addiction among young people? Yes.
Trust them, they’ll warn you if there’s any risk involved.
Not.

Have you ever seen any product manufacturer that linked to scientific evidence supporting their safety precautions?

Here’s another universal precaution (on microwave ovens): “Do not attempt to operate this oven with the door open since open-door operation can result in harmful exposure to microwave energy.”

Would you likewise demand links to scientific studies backing that precaution? If not, why? How is it different from the above-listed precautions on Li-ion storage from all of the top-tier manufacturers?

What the manufacturer’s recommendations are is not the subject of this discussion thread.

However, you’re entitled to your opinion. Feel free to discuss the merits of the manufacturer’s recommendations.
