New Battery Rules For Air Travel Effective January 1

- Rob Bushway

The government has issued new rules for air travel with spare lithium batteries. These rules are effective January 1, 2008:

• Spare batteries are the batteries you carry separately from the devices they power. When batteries are installed in a device, they are not considered spare batteries.
• You may not pack a spare lithium battery in your checked baggage
• You may bring spare lithium batteries with you in carry-on baggage – see our spare battery tips and how-to sections to find out how to pack spare batteries safely!
• Even though we recommend carrying your devices with you in carry-on baggage as well, if you must bring one in checked baggage, you may check it with the batteries installed.

Batteries that are separate from the device cannot be checked in. So, tuck the thing in a machine and it cannot be a bomb. Next stop: you have to swallow the batteries to be able to carry them aboard a plane...
