Posted:From Reuters: They are the latest in ongoing efforts in the airline industry to manage the use of lithium-ion batteries, which are known to combust and are used in many devices, from phones and laptops to toys. Top airlines banned hoverboards during the Christmas holiday season in 2015. Earlier this year, the U.N.'s aviation agency prohibited shipments of lithium-ion batteries as cargo on passenger planes. A January report from the FAA said at least 171 incidents of smoke, fire, extreme heat or explosion involving batteries have occurred since 1991. In some instances, they have caused emergency landings, as when a camera short-circuited and started a small fire in the overhead bin of an American Airlines flight in September 2013.
