Lithium batteries banned from checked luggage

WASHINGTON -- To help reduce the risk of fires, air travelers are no longer be able to pack loose lithium batteries in checked luggage.

Passengers can still check baggage with lithium batteries if they are installed in electronic devices, such as cameras, cell phones and laptop computers. If packed in plastic bags, batteries may be in carryon baggage. The limit is two batteries per passenger.

The ban affects shipments of non-rechargeable lithium batteries, such as those made by Energizer Holdings Inc. and Procter & Gamble Co.'s Duracell brand.

"Doing something as simple as keeping a spare battery in its original retail packaging or a plastic Ziploc bag will prevent unintentional short-circuiting and fires," Krista Edwards, deputy administrator of the Pipeline and Hazardous Materials Safety Administration, said in a release.

The Federal Aviation Administration has found that fire-protection systems in the cargo hold of passenger planes can't put out fires sparked in lithium batteries.

The National Transportation Safety Board said it could not rule out lithium batteries as the source of a cargo plane fire at Philadelphia International Airport in 2006.
