I recently found out that Lithium cells are no longer allowed in checked luggage on airplanes in the US.
Personally I have tortured those lithium button cells and have never had them do anything really dangerous other than spew some nasty stuff out.
I would understand if this referred to litium-ion cells.. Does anyone have any bad expirence with standard lithium coin cells catching fire? Since this seems to be what they are concerned with.[
"Energizer lithium coin batteries are exempt from the classification as dangerous goods as they meet the requirements of the special provisions listed below. (Essentially, they are properly packaged and labeled, contain less than 1 gram of lithium and pass the tests defined in UN model regulation section 38.3)."
However, these comments may have gotting their attention: "Handling: Accidental short circuit for a few seconds will not seriously affect the battery. Prolonged short circuit will cause the battery to lose energy, generate significant heat and can cause the safety release vent to open. Sources of short circuits include jumbled batteries in bulk containers, metal jewelry, metal covered tables or metal belts used for assembly of batteries into devices. Damaging a lithium battery may result in an internal short circuit."
"The contents of an open battery, including a vented battery, when exposed to water, may result in a fire and/or explosion. Crushed or damaged batteries may result in a fire."
I had a 2032 coin cell get shorted by my car keys while in my pocket. No explosion or fire, but it sure burned my leg.
Not exactly a coin battery, but interesting: Primary Lithium battery explodes!

There was an Austrian Airlines jet brought down because a shipment of watches had a large number of the lithium cells in them leak in the unpressurized cargo hold and catch fire.
The "nasty stuff" is extremely flamable in large quantities.

Those who cannot remember the past are condemned to misquote it.

is the flight prohibition against lithium CELLS or battery PACKS? like the laptop PC battery packs that have had fire problems,and would have exposed contacts that could be shorted by other items in the baggage. Or spare cellphone battery packs,out of their OEM packaging.
Are lithium-ion batteries the next threat to airline safety?
FAA data show that from March 20, 1991, through Aug. 3, 2010, batteries and battery-powered devices were involved in 113 incidents with "smoke, fire, extreme heat or explosion" on passenger and cargo planes. The data are for lithium and non-lithium batteries and are not a complete list of such incidents, the agency says.
I think this is what inspired the TSO to step up enforcement:

NASA won't allow any litium cells in space. We had to use 'Capstore' NVRAM in our products for space applications. Since the cost difference was small, we dropped the battery backed NVRAM from our products.

For the last time: I am not a mad scientist, I'm just a very ticked off
scientist!!!
Well I didn't know the regulations, but I was told by the post office here in Japan that no lithium battery Coin cell included or lead acid batteries are allowed in Air Mail.
Go figure they got the translation wrong and of course nobody knows enough about how things work to even ask the question why they are banning it. Honestly I can understand Li-ion batteries being banned, but non rechargable coin cells didnt make any sense to me.
On that note as well.. Did anyone know there is a 1lb / 455gram limit on all parcels flying airmail to the USA? It isnt being enforced everywhere yet, but this is what the TSA requested / demanded.
Lovely. The TSA imposes this limit and Japan retaliates.
Here's the brilliant logic: Packages containing explosives were found in Britain and Dubai on two cargo planes from Yemen bound for the U.S. in late October. The TSA heightened its aviation alert level since then. Therefore, anything weighing over 1 lb must be a bomb.

That would effectively ban all parcels over 1lb to the US, since there is no longer any international surface mail into or out of the US. Such a rule will never fly, as it would pretty much curtail any international small quantity commerce. Would REALLY piss off the troops, too, as it would pretty much mean they couldn't send anything home other than letters. Would also severly cripple military contractors, etc.
