Several writers have recently mentioned the January 1, 2008 limitations on carrying lithium batteries in checked and carry-on luggage. And several of the news sources seem to have gotten it wrong. Go to safetravel.dot.gov for complete information, but the way we read it you can take a lithium battery attached to a device (camera, cell phone, laptop) plus two spares. But the spares must be in your carry-on bag, not checked luggage. The electronic devices themselves (with battery attached) can be in either or both your carry-on and your checked luggage. As with all things governmental and travel related, there are lots of silly exceptions – if you can get through the mumbo jumbo, you should be able to glean the correct information from the SafeTravel website.
