Lithium Batteries

In September 2016, the FAA and DOT issued safety notices related to the Galaxy Note 7, after Samsung recalled the device for safety reasons. Federal hazardous materials regulations prohibit airline passengers and crewmembers from traveling with lithium cells, batteries or portable electronic devices that have been identified by the manufacturer as being defective for safety reasons.

Lithium batteries are used in aircraft in a number of devices. The use in portable electronic devices is probably the most frequent, but they are also installed to provide power for various aircraft systems. When handled improperly, lithium batteries can overheat and ignite, causing fires that are hard to extinguish.

Lithium Batteries in Portable Electronic Devices

As portable electronic devices (PEDs), such as smart phones and laptops continue to increase in popularity, passengers and crewmembers are more frequently bringing these devices on board aircraft. Passengers routinely want to use these devices for the duration of the flight, but one charge or one set of batteries will not always permit that to happen, so spares are brought along. Note that batteries properly installed in the PEDs pose less of a fire risk as long as they are recharged properly.

The Department of Transportation (DOT) regulations for Hazardous Materials (HAZMAT) permit the carriage of lithium and lithium-ion batteries in consumer electronic devices. Packing of spare batteries is an important consideration. The DOT requires the following with respect to lithium and lithium-ion batteries:

  • Spare batteries must be protected from damage and short circuit. This can be accomplished by:
    • placing the spare batteries in their original retail packaging;
    • putting tape over the terminals of the battery to insulate them; or
    • placing each battery in a separate plastic or protective pouch.
  • Spare batteries may not be carried in checked baggage or in baggage areas not accessible during flight.
  • Loose batteries not protected from short circuit are not permitted to be carried in any part of the aircraft.

The FAA has issued a safety alert for operators (SAFO) providing guidance on how to safely extinguish fires caused by disposable lithium and rechargeable lithium-ion batteries. The guidance refers to the need not only to extinguish a fire, but also to cool the batteries to prevent thermal runaway and re-ignition.

Lithium Ion Battery Fire Risk: Education Key to Mitigationt
June 20, 2018
Virtually every air traveler is carrying a device powered by a lithium ion battery, and most passengers are traveling with more than one such device. Over the past several years, the FAA’s Fire Safety Branch has been conducting research on the risk of in-cabin fires related to lithium ion batteries and potential methods to mitigate such risks. At this week’s NBAA Flight Attendants/Flight Technicians Conference, attendees will hear from Steve Summer, an engineer in the FAA’s Fire Safety Branch, about the results of research conducted on handling in-flight lithium battery-related fires, and the unique hazards of these incidents.
