For those of you who travel by air with your cameras, be aware that as of January 1, 2008, it’s no longer legal to put lithium ion batteries in checked baggage. From now on, all spare lithium ion batteries must be kept in carry-on bags, with the terminals covered. REVISED: The US Department of Transportation has clarified its rules. Small lithium-ion batteries – like the types that are used in laptop computers and cameras are exempt from the new rules becuase they contain less than 8 grams of lithium. So, you should be able to travel normally, even after the new restrictions.
These days, most cameras use either Lithium Ion or Nickel Metal Hydride batteries. Lithium Ion batteries are usually marked with an Li-Ion monicker of some kind.
Obviously, batteries in your camera aren’t a concern, unless you’re hoping to put your camera in your checked bag, which is usually not a good idea, for any number of reasons.
Most spare batteries ship with covers for the contacts and it’sa good idea to use these when packing your batteries.
Though I’ve never tested this, it’s probably better to carry on your batteries anyway, as keeping them in your checked baggage could subject them to cold that will make them lose their charge. Cold won’t permanently damage your batteries, but it could result in them needing to be topped off.
