Effective January 1, 2008, spare lithium batteries - extra batteries not installed on devices - will no longer be allowed in checked baggage. Spare lithium batteries may be packed in carry-on baggage and lithium batteries installed in a device may be packed in either checked or carry-on, as long as the battery is installed in the device, according to the Transportation Security Adminstration (TSA).

New US DOT Hazmat Safety Rule to Place Lithium Battery Limits in Carry-on Baggage on Passenger Aircraft Effective January 1, 2008

Passengers will no longer be able to pack loose lithium batteries in checked luggage beginning January 1, 2008 once new federal safety rules take effect.  The new regulation, designed to reduce the risk of lithium battery fires, will continue to allow lithium batteries in checked baggage if they are installed in electronic devices, or in carry-on baggage if stored in plastic bags.

Common consumer electronics such as travel cameras, cell phones, and most laptop computers are still allowed in carry-on and checked luggage.  However, the rule limits individuals to bringing only two extended-life spare rechargeable lithium batteries (see attached illustration), such as laptop and professional audio/video/camera equipment lithium batteries in carry-on baggage.

"Doing something as simple as keeping a spare battery in its original retail packaging or a plastic zip-lock bag will prevent unintentional short-circuiting and fires," said Krista Edwards, Deputy Administrator of the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration.

Lithium batteries are considered hazardous materials because they can overheat and ignite in certain conditions.  Safety testing conducted by the FAA found that current aircraft cargo fire suppression system would not be capable of suppressing a fire if a shipment of non-rechargeable lithium batteries were ignited in flight.

"This rule protects the passenger," said Lynne Osmus, Federal Aviation Administration (FAA) assistant administrator for security and hazardous materials.  "It's one more step for safety.  It's the right thing to do and the right time to do it."

In addition to the new rule, PHMSA is working with the FAA, the National Transportation Safety Board, the Consumer Product Safety Commission, the battery and airline industries, airline employee organizations, testing laboratories, and the emergency response communities to increase public awareness about battery-related risks and developments.
