TSA limits lithium batteries on airplanes

yali writes: The U.S. Transportation and Security Administration has issued new rules limiting travel with lithium batteries. As of January 1, no spare lithium batteries are allowed in checked luggage. Batteries carried in the cabin are subject to limitations on per-battery and total lithium content, and spare batteries must have the terminals covered. If you're returning home from the holidays with new toys, be sure to check out the new restrictions before you pack.
