New security rules for batteries on planes

If you don't want to lose your spare lithium batteries for your camera, notebook or cell phone, you might want to pack carefully for your next flight.

New rules from the Transportation and Security Administration that take effect on January 1 ban travelers from carrying loose lithium batteries in checked baggage. Passengers are allowed to pack two spare batteries in their carry-on bag, as long as they're in clear plastic baggies.

Fortunately, you don't have to worry about the batteries that are already installed in the devices you're bringing. The TSA has said it's safe to check in items like a laptop or iPhone that already have the batteries in place.

The agency said that loose lithium batteries not installed in devices pose a fire risk to passenger planes. Recently, the National Transportation Safety Board could not rule out the possibility that lithium batteries started a fire in a plane at the Philadelphia National Airport last year, according to the Associated Press.

If you do plan on bringing spare batteries in your carry-on bag, be aware of some other rules: You can only bring batteries with an equivalent of up to 8 grams of lithium content. (Most batteries for cell phones and laptops meet this requirement.) And for lithium metal batteries, whether carried as a spare or installed in a device, batteries are limited to 2 grams of lithium metal.

Batteries starting fire.

"Recently, the National Transportation Safety Board could not rule out the possibility that lithium batteries started a fire in a plane at the Philadelphia National Airport last year [http://...|http://...]" What??? So, with this logic, anything that can create a fire is a security risk. Do you know how many things can actually be used to create fires? A magnifying glass, certain types of stones, even little pieces of wood (you know, like the ones they give you in restaurants, what are they called? Toothpicks?). Or, HOW ABOUT THE BOXES OF MATCHES THEY LET PEOPLE TRAVEL WITH INSIDE THE PLANE! But no, even though fire is a security risk, the easiest method of producing one (matches) is not taking out of the equation and instead blamed on something else (batteries) because "it's possible"... F***ing brilliant thinking on NTS part. So now I can't work during the fight because my onboard battery runs out too quickly with all the programs I'm dealing with at once. Oh no, wait, it's alright, if I put the battery inside a plastic bag it's fine! What? What kind of twisted game are they playing here? "The battery is dangerous! It may kill us all! Ah, but through a thin layer of plastic, everything will be fine." Stupid scare tactics. How pathetic!

If you don't like it contact DOT and the FAA...

These batteries are considered HAZMAT due to fire hazard. How quickly would your family sue if one started a fire on the plane and you died? It was only a matter of time given past problems with Lithium batteries, we've been dealing in my company for years with the restrictions on sending them by air freight.

Clip Art?

What's with the fighter jet airborne refueling clip art? A fighter jet will come shoot your plane down if it is taken over by terrorists wielding batteries?

TSA A**holes are simply conditioning the sheeple to accept that they can be f**ked with anytime the government wants. Get out now, while you still can!! The USA is going to collapse under the weight of it's number one product - Bullsh*t!!

Spare Batteries Hot?
by oobflyer December 30, 2007 9:35 AM PST
I thought batteries got hot while in use, or while charging... how could spare batteries pose a threat while packed in a suitcase?

A thing or two about lithium batteries
by gmorita December 30, 2007 11:34 AM PST
While I disagree with the NTSB decision I understand some of their reasoning since my work has involved the design and use of lithium batteries. The NTSB has had these restrictions on the shipment of lithium batteries for in place several years. I just don't agree with extending the rules to passenger aircraft. The major problem with lithium ion batteries is the fact that once they catch fire they CANNOT be extinguished. Current lithium ion batteries contain organic solvents (a fuel) AND an oxidizer (cobalt oxide). When the interior of the battery reaches about 175C the cobalt oxide cathode breaks down and liberates free oxygen which then reacts with the organic solvents (think of mixing kerosene and liquid oxygen as in rockets). Once the reaction starts it generates more heat which releases more oxygen which generates more heat and so on. Primary lithium batteries have a similar problem except they use lithium metal and manganese dioxide. Which under the right circumstances can create a fire that cannot be extinguished. I have seen a battery of the same type used in cameras explode and blow the door (2'x2') off an environmental chamber. Since the fuel and oxygen are in such close proximity, the only way to stop the fire is to rapidly reduce the temperature (think liquid nitrogen). CO2 extinguishers are useless since the lithium will burn in the CO2 by stripping the oxygen away from the CO2 molecule. Again, I don't agree with the NTSB decision to extend the restriction to passenger aircraft but I have seen first hand the dangers lithium batteries pose.

Did anyone read the new rules? Certainly not the CNET "journalist"

Limitations of two grams are for lithium metal, and I still have not seen which batteries are in common use that are over 2 grams of lithium. My concern was about implications for traveling with Lithium ion batteries. Most consumer electronics batteries that use lithium are Li-ion technology. Here is my interpretation, as long as they are in carry on luggage, there is no limit on the number of Li-ion batteries with lithium equivalence under 8 grams (this includes all internal laptop batteries that I know of). You can only carry two spare Li-ion batteries which fall between 8 and 25 grams. Here is the direct quote from the DOT web site: "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." NOTE THIS PHRASE--- "IN ADDITION TO ANY BATTERIES THAT FALL BELOW THE 8-GRAM THRESHOLD". Visit here for the real story, though less than clearly written: http://safetravel.dot.gov/whats_new_batteries.html Of course, the real proof of this will be in how it is enforced by the TSA.

Just FYI, the picture with the story is not of a passenger plane, but of a military fefueler.

What else could it be.....
by technikallyright December 31, 2007 5:55 AM PST
Is it possible that the "threat" is not real Li batteries but what could be packed in luggage in a Li battery case? Just a thought......Lockerby anyone?
