DOT bans checked, loose lithium batteries on flights starting Jan 1st 2008

It was announced that starting January 1st, 2008, you can no longer pack "loose lithium batteries" into your checked luggage on flights. If your battery is attached to a device (cellphone, laptop, PSP, camera, etc.) -- or is packed into a plastic bag -- then you're okay. According to the report, "Common consumer electronics such as travel cameras, cell phones, and most laptop computers are still allowed in carry-on and checked luggage," though, "The rule limits individuals to bringing only two extended-life spare rechargeable lithium batteries, such as laptop and professional audio/video/camera equipment lithium batteries in carry-on baggage." The new ban is related to lithium batteries' propensity to explode, and not due to any terrorism concerns. This may not affect all travelers as normally we wouldn't carry spare batteries as we have the all mighty charger. Just for portable device fanboys, take note.
