Airplane Cargo Holds Can Be Too Hot for Li-Ion

By - Source: Tom's Hardware US | B 21 comments

Could this limit what you take with you on holidays?

The Transport Security Administration (TSA) has mandated since 2008 that no loose lithium ion batteries may be packed in with checked luggage. This means that all your spare batteries will be going in with your carry-on, which may not be a bad thing if your flight doesn't have any in-seat power.

If you don't want to deal with the added shoulder weight, you'll have to pair the lithium ion battery with the device. (Read more about the rules here.)

New findings brought to light by the Federal Aviation Administration (FAA) say that lithium ion batteries are sensitive to heat and can ignite in a hot environment. Of course, that is a characteristic of batteries in general, but the new research could lead to an even further more restrictive set of guidelines for what people can bring when flying.

The FAA also acknowledged publicly that the UPS 747-400 plane that crashed in Dubai earlier this year was carrying a large quantity of lithium batteries.

    These regulators are slightly overzealous...

    Li-Ion batteries only ignite at fairly high temperatures (around 600 C), which I doubt will be reached in a cargo room. Defective batteries are of course far more prone to ignition (due to thermal runaway), but how many people take a defective battery with them?

    Okay, terrorists and really stupid people might, but we can't forbid everything... When will people and governments learn to accept that you cannot prevent everything? Sometimes, a marginal bit of safety does not outweigh a loss of freedom and convenience.

    beamthegreatlol?



    dude stop loling at the first post of each story. Its really anoying. u have loled at a plane crashing, at a disabled boy using an ipad, and at a translation app. NONE OF THOSE ARE FUNNY.

    the plane in Dubai crashed right after take off... The batteries couldnt've ignited in such a short period of time, unless it was in the plane for a few days already

    It must have been something else besides batteries.

    i agree. Better safe than sorry. And you won't know what terrorists will do....maybe they hide leaked lithium-ion batteries inside Everyready bunnies and make some timer to leak it and set to detonate or something. Who knows.

    Not all batteries which pass certain tests are consider safe that's why the FAA ruled out to restrict all lithium batteries for safety.

    I thought the cargo hold of airplanes was cold. I was sure I read a article talking about pets in the cargo hold, is it safe for them because it's very cold when at altitude.

    Ditto. What causes heat in the cargo hold? Ambient temperatures building up on a hot day somewhere?

    Simple reason. Crashed plane = $$$.

    go to youtube and search lithium ion battery fires, like the kind apple uses or cameras or just about any laptop. all it takes is way too much overcharging and then your luggage bag is full of nice combustibles in a flying coffin with a limited oxygen supply which incidentally will only make the fire burn hotter and faster. when at high altitude if the fire doesn't get you first asphixiation will. it will all be over in a few minutes as that plane will not be able to get to the ground fast enough. if that doesn't bother you you must have a parachute in your carry on bag?

    what happens when you get locked into a non-ventilated metal box on a 90-110º day? just sayin. batteries don't have sweat glands.

    cargo holds are cold when at high altitude, which is why the pilots turn on a heater in the cargo hold. the cargo hold doesn't need air conditioning as it's not typically holding anything living. so unless they are flying ice cream or puppy dogs the temp is what ever is outside except on the ground, then it's a locked metal box, and in dubai it was probably a 114ºF day with a typical bright sunny day beating down on all that nice metallic aircraft skin making it into a nightmare of a sweatbox.
