New Dept of Transportation airline rules concerning 'lithium' 'batteries' in carry-on luggage.

Thanks for the heads up. I'm flying on the 6th, this is good to know.

I normally travel with...

GPS unit = 2 'batteries'
Digital camera = 4 'batteries' (with 2 of those being spares)
MP3 / CD player = 2 'batteries'
Laptop = 1 (although their 'batteries' don't count against you)
Plus a handfull of extras just because I'd hate to be somewhere and run out of juice!

I guess this isn't neccessarily a bad rule because you probably don't need all of these items WHILE YOUR FLYING. This is good information to know though. Thanks

Glad I bumped into this thread. Flying up there on the 6th.

according to the article, just put your spare 'batteries' in a zip lock or other plastic container (instead of loose) and you should be fine to keep everything with you.

And make that THICK individual bags for each battery. The intent is to keep the contacts from touching any material that could short out the battery and cause extremely high currents. This goes for any battery you are carrying that isn't installed in a device. Currents on some ni-cads can reach 300 amps for a very short period of time short circuited. Under these conditions Li-Ion 'batteries', especially the new 'Lithium' polymer can explode violently. Most DSLR 'lithium' packs come with a plastic snap-on cover to protect the contacts. I'd recommend always keeping this on when it's not in the camera or charging. Not just when flying, but at home or in the field.

So why aren't you guys using Ni-MH 'batteries'? I thought everyone had switched over to them instead of 'Lithium'?

(I assume this law does not concern Ni-MH 'batteries')

Okay, so I'm a dunce... all of my AA 'batteries' are Ni-MH and I just assumed the "world" was going to Ni-MH. But I just checked ... the 'batteries' for my Canon bodies are all 'Lithium' Ion 'batteries'.

As you were...

So if I'm reading this right, you can have unlimited 'batteries' as long as they're installed, but only two spares in baggies in carry-on. Spares even in baggies are not allowed in checked bagged, correct?

I just want to get this straight since I'm flying on Sunday. So I CANNOT carry my 3 spare 'batteries' for my Canon? I have 5 total but two are always in the battery grip.

Try leaving two in the battery grip, take the grip off the camera, store one in the camera, and two in ziplocks!

The two spares is related to 'batteries' between 8 and 25 grams of 'lithium'. (at least that's what I've read)

'Batteries' like the BP511 (from what I've read) have less than 1 gram of 'lithium' each. If you keep the plastic back on them so the terminals aren't exposed then you're storing them properly.

I think the trouble will arise with insufficiently trained security personnel. Take a print of what is stated on the DOT site with you and highlight any areas that are pertinent to your equipment.

Also, Sam's advice is good to avoid confusion.

This is why I love this place. :) That's a great idea!

Didn't know I gave any advice...but sure!

IANAL, but from my reading of it, the important lines of the announcement for photographers are:

Originally posted by The DOT:

Common consumer electronics such as digital cameras, cell phones, and most notebook computers are still allowed in carry-on and checked luggage. Moreover, any number of spare 'batteries' for these devices will be allowed in carry-on baggage if they are properly protected from short circuiting and do not exceed 8 grams (~100 watt hours) of equivalent 'lithium' content. All 'lithium'-ion cell phone and standard notebook computer 'batteries' are below 8 grams (~100 watt hours) of equivalent 'lithium' content. 'Batteries' not installed in electronic devices are not permitted in checked baggage.

This means that you can take as many small 'batteries' with you in hand luggage as you like, as long as they are seperately bagged, and don't total more than 8g of 'lithium'. You probably won't ever exceed the latter unless you're carrying 10+ camera 'batteries' or 2+ laptop 'batteries', so just make sure you bag them all individually and you should be fine...
