Effective January 1, 2008, passengers on planes will no longer be able to carry loose rechargeable lithium batteries (the kind that are commonly used in digital cameras, camcorders, and laptops) in their checked baggage. However, you can have them in your carry-on bags, as long as they’re in their original packaging or in a simple resealable plastic bag. And you’re limited to a total of only two spare rechargeable lithium batteries in your carry-on bags. It seems that under certain circumstances, these batteries can explode and catch fire. Hmmm. Makes me wonder what exactly are those circumstances? So if you’re traveling, plan ahead. And just to be safe, don’t carry lithium batteries in your pants pockets. Ouch.
