A. There are Federal regulations with very specific provisions regarding transportation of batteries and battery-powered equipment in checked and carry-on baggage on passenger aircraft. On March 26, 2007, PHMSA issued a safety advisory notice about the importance of properly packing and handling batteries and battery-powered devices when they are carried aboard aircraft. Guidelines on the safe carriage of batteries and other commonly carried consumer items (e.g., lighters, matches, aerosols, and ammunition) are available for travelers at safetravel.dot.gov
