> So we had to take the bad battery, still fully charged despite being blown up like a balloon, with us on an airplane so we could take it home and dispose of it properly. That was incredibly dangerous and put everyone on the airplane at risk. You didn't have to take it.

I am well aware of that, and it was not a decision I made lightly. FWIW, it was several days between removing the battery and the flight, and I monitored it closely to make sure it wasn't continuing to expand or throwing off any heat. But the alternative would have been to throw it in the trash, and that had risks of its own.

  Throwing it out would have been preferable although almost every municipality has proper waste disposal facilities to take it. I don't think you understand just how dangerous these things are in an airplane.

    I'm a pilot. I understand it quite well.

      I choose to believe you actually don't know the risks becaues the alternative is that you are a terrible human being. It seems vastly more likely that you simply don't understand that you risked everyones lives.

        If you really feel the need to think ill of me then I am not going to stand in your way, but please consider the possibility that I really do understand and that I took appropriate precautions. (You might even think to ask me about those before passing judgement.) Also, you should keep in mind that lithium batteries can catch fire with no warning signs at all, so just because your laptop battery hasn't swollen up is no guarantee that it is safe. Have you ever taken a laptop on a plane? Does that make you a terrible person who risked everyone's lives?

        Lithium batteries contain safety systems that become compromised when the part is mechanically deformed. A damaged battery is significantly more dangerous than an undamaged one (although undamaged batteries aren't really safe either). As the Li-Ion batteries contain their own oxidizer a fire caused by one is extremely difficult to contain. There are no FAA approved ways to transport damaged Lithium batteries that I'm aware of - but since your a pilot perhaps you could enlighten?
