If you've been packing extra lithium batteries in your checked bag before a flight, you might want to avoid doing so in the future. The FAA warns that storing those batteries in luggage that'll travel in the cargo hold can "present a risk of both igniting and fueling fires." The agency wants airlines to prohibit the practice and to remind travelers at check-in not to stow extras in a checked suitcase. Worried about running out of juice for that toothbrush or point-and-shoot camera? You might want to wait until you land to pick up more batteries.
