TSA Limits Lithium Batteries on Airplanes

yali writes "The U.S. Transportation and Security Administration has issued new rules limiting travel with lithium batteries. As of January 1, no spare lithium batteries are allowed in checked luggage. Batteries carried in the cabin are subject to limitations on per-battery and total lithium content, and spare batteries must have the terminals covered. If you're returning home from the holidays with new toys, be sure to check out the new restrictions before you pack."

    I expect that many spare batteries will simply be seized and tossed in the trash.

    Try sold on eBay instead. Seized property is typically sold by the states in Surplus Property auctions, where it can be bid on by the public at large, or in some cases the airports themselves sell the stuff in lots on eBay. The government is making a buck on the battery it confiscates from you.

  3. Lithium Ion too - just not as restrictive by El+Gigante+de+Justic · · Score: 5, Informative

    From the TSA webpage, it does apply to some Lithium-Ion batteries.
            Batteries up to 8-grams "equivalent lithium content" installed in devices or as spares are allowed. For Lithium-ion batteries between 8 and 25 grams aggregate lithium equivalent content are also allowed, but you can only have 2 total (both spare and installed).
            Lithium Metal batteries just have tighter restrictions.

    As for the reasons behind this (since some apparantly didn't read TFA)- it sounds like there was a cargo hold fire on one plane caused by lithium batteries and apparently the current fire control systems in planes can't handle lithium fires.

  4. Safety issue not terrorism by calidoscope · · Score: 4, Informative
    Restrictions on shipping lithium primary batteries by air cargo have been in place for over a year now and this also applied to equipment with lithium primary batteries. There are similar restriction for shipping large lithium secondary batteries.


    The news rules do make sense, a in-flight fire on an airliner is pretty serious, especially if there is no nearby place to land (e.g. halfway between California and Hawaii).

    Figures the one time I don't have mod points is the one time I see a post by someone who obviously didn't read the actual links. Lithium batteries are NOT "now illegal to carry". There's just some rules being put in place for when they can be in checked baggage or must be carried on, and how they must be stored. Looking at the actual page on the subject, it looks like they went to great lengths to make sure it won't directly impact most travelers with regards to the batteries people tend to travel with. On that note I see nothing anywhere suggesting that this has anything to do with terrorism. And as you say if it's "to reduce the possibility of a lithium battery shorting out" then they can be in their shipping packages and be "no more dangerous than many other items that you can carry on planes". Which is exactly what they suggest for storing spare batteries.

    I'm all for government conspiracy theories and thinking most of this stuff is completely idiotic. But nothing is going to improve if we go around making grossly inaccurate statements about what a rule actually is.

    Read the article - it clearly states that installed batteries are exempt.
    The AP article may state this, but the DOT page does not. Installed batteries are also subject to limits -- from the DOT page:

    The following quantity limits apply to both your spare and installed batteries. The limits are expressed in grams of "equivalent lithium content." 8 grams of equivalent lithium content is approximately 100 watt-hours. 25 grams is approximately 300 watt-hours:

  7. Very vague information by amper · · Score: 4, Informative
    What really bothers me about this is that the info page from the TSA provides only very vague information concerning exactly what is or is not permitted, and the rules seem to be defined so poorly as to beg for inadvertent violation of the rules by passengers as well as violation of passengers' rights by overzealous security personnel.

    There is no distinction made between non-rechargeable and rechargeable batteries. This may be for a good reason, but the TSA page seems to refer primarily to rechargeable batteries.

    • Under the new rules, you can bring batteries with up to 8-gram equivalent lithium content. All lithium ion batteries in cell phones are below 8 gram equivalent lithium content. Nearly all laptop computers also are below this quantity threshold.
    • You can also bring up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any batteries that fall below the 8-gram threshold. Examples of two types of lithium ion batteries with equivalent lithium content over 8 grams but below 25 are shown below.
    • For a lithium metal battery, whether installed in a device or carried as a spare, the limit on lithium content is 2 grams of lithium metal per battery.
    • Almost all consumer-type lithium metal batteries are below 2 grams of lithium metal. But if you are unsure, contact the manufacturer!


    Note the specification of the word "aggregate" in the second item. That word doesn't appear in the first item. Does that mean I can bring *any number* of batteries that have an individual lithium content of less than 8-grams?

    Note the specification of "lithium metal battery" in the third and fourth items. This term does not appear in either of the first or second items. The first and second items refer to "lithium ion batteries". What is the distinction between a "lithium ion battery" and a "lithium metal battery"? Even worse, in the second item, the term "lithium ion battery" is only referred to as an example. The operative phrase only says "up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any batteries that fall below the 8-gram threshold".

    Can anyone cite the relevant regulations rather than this public info disaster?

    that you not travel with recalled batteries. http://safetravel.dot.gov/remember.html

    Other things that you can find are why they are doing this e.g. flight crews can better monitor safety conditions to prevent an incident, and can access fire extinguishers, if an incident does happen -- http://safetravel.dot.gov/tips.html

    YOU CAN TRAVEL WITH MOST LI-ION CONSUMER BATTERIES assuming the TSA agents follow the rules as stated

    For the lazy people not willing to look at the actual page, nor the willingness to get through the TSA's obtuse writing here is the punch line:
    The following quantity limits apply to both your spare and installed batteries. The limits are expressed in grams of "equivalent lithium content." 8 grams of equivalent lithium content is approximately 100 watt-hours. 25 grams is approximately 300 watt-hours:
    * Under the new rules, you can bring batteries with up to 8-gram equivalent lithium content. All lithium ion batteries in cell phones are below 8 gram equivalent lithium content. Nearly all laptop computers also are below this quantity threshold. -- My Macbook Pro battery is 60 watt hours or about 5.5 grams of lithium
    * You can also bring up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any batteries that fall below the 8-gram threshold. Examples of two types of lithium ion batteries with equivalent lithium content over 8 grams but below 25 are shown below ( the picture shows a pro-camcoder extended use battery and an external extended use laptop battery).

    I usually travel with 10 or more Li-ion batteries of various sizes and this language does not lead me to believe that I will have any trouble because I never check my batteries.I am still concerned as enforcement of these new rules is left up to poorly trained agents, so I worry about losing very expensive batteries because one idiot see lithium on the label and chucks it.

    I am a commercial pilot. I've had a large battery go into thermal runaway in flight. It scared the hell out of me. The flight crew put it in a metal trashcan (so the firefighting gloves are a good idea) and I had depresurized and was going to toss it out over Kansas when it stopped venting and pulsing. I didn't see it; I was on oxygen up front, but my crew really wanted to throw it out even though it stopped pulsing.

    So yeah, this is an annoyance, but, in retrospect, I think it's a good idea, and thinking about the spare laptop battery showed into a pocket with some random AV cables, it could light off the overhead compartment before anyone notices.
