So thats two models of phones that explode or set themselves on fire, a wall charger with illegal insulation imported to America, two models phone phones AND tablets that destroy SDCards likely due to faulty or cheap voltage regulators and a washing machine that sets houses on fire, not exactly a stellar record over the last 5-10 years...

>* But what is the maximum possible damage from a burning battery?* As opposed to the one from bottled water?

I think the point is that it might not water...

In that case your "small toothpaste" (which is allowed) might not be that either.

And you can always dilute it in your air-hostess delivered water if you're so inclined and you just need to have your poison/whatever in liquid form...

There are people who think their laptops do not have a battery at all and run on their own power like a human does.

...well, I didn't see that one coming!

I know people that still believe that the power for cordless drills gets transmitted from the charger to the drill via something like wifi. They're super-careful not to stand in the LOS between the drill and the charger.

Rechargable Lithium batteries contain surprisingly limited amounts of it. And its not in there in its elemental form anyway. Lithium batteries burn because of the potential energy they have after charging. You can drive nails through discharged Lithium Ion batteries without much happening.

Please don't do this, when rechargable lithium batteries are "discharged", they are not discharged fully, doing so would damage the battery. Charging circuits have a "cutoff" voltage where they report the battery to be empty, but there is still plenty of stored energy in the cells.

There is very little energy left past the "knee" where the cutoff is.

The threat they are trying to guard against is binary liquid explosives, where you mix two liquids to make a bomb, so volume does matter.

Of course, it's a idiotic way to accomplish their goal anyway, but their goal is idiotic anyway, so it's all security theater anyway.

Clearly not. Mac users are used to their laptops actually going to sleep when they shut the lid. My work HP, however, is regularly scorching hot when I get home as it's been on in my backpack the whole time despite me shutting the lid and despite the instruction to 'go to sleep when the lid is closed'. How there's not some sort of thermal cutoff I do not know, but I know for a fact that there is not. Edit: by 'regula…

For the record, this happens a few times a year too with my MacBook Pro.

Then you should probably return it. This is not normal behavior.

The risk is only while the Samsung device is charging (as I recall?). As for other devices, I suppose they could issue the warning "please do not hit your device with a hammer during flight". Fun fact I read recently: more than a million people are in the air at any one time, globally. If laptop batteries exploded even rarely, we'd hear about it.

The Aviation Herald lists a few incidents involving batteries: http://avherald.com/h?search_term=batter&opt=0&dosearch=1&se...

Nice find. No doubt batteries are a hazard particularly when exposed/not installed in devices as many of these examples describe... batteries found squashed between the seat and so on. If we remove cases of smoking loose batteries, or crushed devices in luggage, the failure rate is extremely low.

I wonder why they aren't being banned, the way that hover boards were (though I believe the fire risk for the Note 7 is only present while charging)

Risk might not be great enough. They're balancing convenience and safety. IIRC the hoverboards had a higher risk because of how many cheap ones burst into flames and people didn't want to use them in flight so it wouldn't bother them if they didn't have them.

The "hoverboards" have a much bigger battery, with far more stored energy, and are also designed such that they can release that energy more quickly since the application requires it. A typical phone has around 10-15Wh capacity, hoverboards are in the 150-100Wh range, and laptop batteries are usually <100Wh; these are also cells which are designed more for long low-current discharges.

Now I hope samsung will bring back the removable battery. The only reason I can still use my note 3 is because I was able to easily replace the battery with a new one. In fact all phones should have accessible batteries as the battery is in my opinion a consumable which will need replacing at some point.

That's why I switched to the LGV10 -- which has a removable battery. It's successor the V20 also has a removable battery. Nothing beats going from 5% charge to 100% in 15 seconds.
