TSA Clarification (?)

Effective January 1, passengers can no longer pack loose batteries in checked bags. Unlimited loose batteries are allowed in carry-on bags, though they recommend separating them in individual zippered bags or compartments if not in their original packaging. There is one exception: Passengers carrying lithium batteries that have 8 to 25 grams of equivalent lithium content are limited to two uninstalled batteries in each carry-on. Most electronic items such as laptops, digital cameras and cellphones use batteries that fall far short of that content.
