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.

Below are some tips for safe travel with batteries:
Keep batteries and equipment with you, or in carry-on baggage - not in your checked baggage! In the cabin, flight crew can better monitor conditions, and have access to the batteries or device if a fire does occur.
 
If original packaging is not available for spare batteries, effectively insulate battery terminals by isolating the batteries from contact with other batteries and metal. Do not permit a loose battery to come in contact with metal objects, such as coins, keys, or jewelry.
 
Place each battery in its own protective case, plastic bag, or package, or place tape across the battery's contacts to isolate terminals. Isolating terminals prevents short-circuiting.
 
Take steps to prevent crushing, puncturing, or putting a high degree of pressure on the battery, as this can cause an internal short-circuit, resulting in overheating.
 
If you must carry a battery-powered device in any baggage, package it to prevent inadvertent activation. For instance, you should pack a cordless power tool in a protective case, with a trigger lock engaged. If there is an on-off switch or a safety switch, tape it in the "off" position.
 
Lithium batteries are considered a hazardous material because they can overheat and ignite in certain conditions. Safety testing conducted by the Federal Aviation Administration (FAA) found that current aircraft cargo fire suppression systems are not capable of suppressing a fire if a shipment of primary lithium batteries is ignited in flight.
 
The Transportation Security Administration (TSA) has and will continue to work closely with the FAA on potential aviation safety and security issues, and TSA security officers are thoroughly and continually trained to find explosive threats. For more information, please visit http://www.tsa.gov
