New Laptop Battery Rules from TSA
If you'll be travelling by air in 2008 be sure to review the new rules for carrying batteries on airplanes. The new battery rules are here at TSA's websiteOn new rule is that you are NOT allowed to pack lithium batteries in your *checked* luggage, though you *are* allowed to have them in carry on baggage in clear plastic bags.It's also a good idea to review the 3-1-1 rule here at TSA:3-1-1 for carry-ons = 3 ounce bottle or less (by volume) ; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin.
