About Lithium Battery Regulations:

• Function: Lithium batteries are commonly used in electronic devices, such as cell phones, laptops, PDAs and electronic Watches. They are also used in long-term electronic medical devices that are implanted in patients, such as pacemakers, where the battery may last for more than 15 years. In other electronic devices, lithium batteries are preferred because they have a longer life than regular alkaline batteries, yet they are used with caution due to its high voltage
• Regulation: Lithium Cell ReplacementOn January 1, 2008, the regulation restricting the air tranSport of uninstalLED lithium batteries in checked luggage was passed by the United States Transportation Security Administration. This prevents the transport of extra lithium batteries in the luggage that will go to the airplane's cargo areas
• Exception: The regulation does allow the presence of extra lithium batteries in the carry-on luggage. This does not restrict the number of batteries that is packed. However, the concern is that if a lithium battery did explode, an airplane attendant could use fire prevention measures to extinguish the fire, whereas an explosion in the cargo area may be discovered too late
• Effects: Turn electronic devices that use lithium batteries off during air transport and secure the battery from being activated by enclosing the device in its proper case. This will secure the lithium battery during air travel
• Considerations: To prevent short circuits or activation, pack batteries with a piece of tape secure across the battery's terminals to prevent accidental contact with other conduit surfaces, such as any type of metal. New, unopened batteries are already secured in this fashion, so also consider traveling with packaged batteries
