Because some have been known to spontaneously combust, the Department of Transportation (DOT) is banning some lithium batteries from your checked-in luggage. In the spring, a laptop battery related fire erupted in the overhead compartment of a Jetblue flight, and on an American Airlines flight from Argentina, prompting the DOT to issue a warning about packing spare batteries. Lithium batteries are commonly used in laptops and cellphones. However, the rules mainly apply to professionals and/or people who travel with spare batteries. For the most part, batteries installed in the electronic device are fine. Inside, a handy chart to tell you what’s been banned.
