Lithium Batteries: A Hot Topic

Learn about the risks, the data and how the FAA helps prevent lithium battery incidents on aircraft.

A lithium battery on fire

Lithium batteries are in products we use every day — from laptops and hand-held devices, such as vapes and cell phones, to battery-powered tools and electric vehicles. However, they can be dangerous on aircraft if not packed or shipped properly.

Look at the Data

From January 23, 2006, until July 22, there were 398 reported aviation-related incidents involving lithium batteries that were carried as cargo or in passenger baggage.

There were 42 reported incidents involving vapes or e-cigarettes on aircraft since 2020 with the majority of those being on passenger aircraft. And for the 41 lithium battery incidents reported through July of this year, e-cigarettes/vapes were in the lead for category of incident. Incidents involving battery packs or spare batteries seemed to surge in 2017.

Chart with lithium battery incidents from 2009–2022.
The FAA’s Lithium Battery Incident charts include a running list of aviation cargo and passenger baggage events involving smoke, fire, extreme heat or explosion involving lithium batteries or unknown battery types dating back to 2006.

Understand the Risk

Smoke in the aircraft is a definite cause for alarm, but do you know why lithium batteries pose a risk? Learn more in this video.

Why should spare batteries and lithium battery-powered devices be kept with you in the cabin? If the battery does begin to smoke or catch fire, the trained crew can be alerted and respond quickly. Passengers can learn how to safely pack bags to reduce the risk from these and other common dangerous goods with the resources at the bottom of this page or the FAA’s PackSafe chart.

Damaged or recalled batteries and battery-powered devices, which are likely to create sparks or generate a dangerous evolution of heat, must not be carried aboard an aircraft (e.g. carry-on or checked baggage) unless the damaged or recalled battery has been removed or otherwise made safe. The airline may offer further public guidance on transporting individual recalled products.

Helping Prevent Incidents

The FAA takes several approaches to reduce the risk of aviation incidents including testing, regulation changes, international collaboration on standards, training and outreach. Information sources such as the Lithium Battery Incident reports help to inform these efforts. Here are a few things the FAA is doing to help prevent or respond to aircraft incidents involving lithium batteries:

Battery testing

  • The FAA’s William J. Hughes Technical Center includes a vast array of state-of-the-art laboratories to enable research, engineering, development, test, and evaluation of advanced aviation technologies and to ensure that risks introduced to the aircraft can be mitigated. The Fire Safety Branch’s research focus areas include cargo, propulsion and fuel systems, cabin interior fire protection, and advanced fire-resistant materials. Lithium batteries are included in this research, watch some of our testing videos.

Collaboration on standards

Education for passengers, shippers and airline crew
