Laptop Batteries: Suddenly Dangerous

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."
