Lithium batteries can overheat, short-circuit, and catch fire
Lithium-ion batteries are generally safe. However, they can overheat, short-circuit, and catch fire if they are damaged or defective. This is a concern for airlines because, in the event of a fire, flight attendants can respond to the issue more quickly if it occurs in the cabin rather than in the cargo hold.
Lithium-ion batteries are found in many consumer electronic devices, such as smartphones, tablets, laptops, cameras, and electronic cigarettes. These devices are allowed in carry-on baggage but must be turned off and protected from accidental activation and damage. Spare lithium-ion batteries, including those for portable rechargers and vaping devices, are prohibited in checked baggage and must be carried in carry-on baggage.
To prevent short circuits, battery terminals should be protected by the manufacturer's packaging or covered with tape and placed in separate bags. Additionally, passengers should take steps to prevent crushing, puncturing, or putting a high degree of pressure on batteries, as this can cause an internal short circuit, resulting in overheating.
If lithium-ion batteries are damaged, defective, or recalled, they must not be carried in carry-on or checked baggage. This is because damaged or defective batteries can release flammable electrolyte vapors, which, combined with an ignition source and oxygen, can cause a fire.
To reduce the risk of incidents, passengers are encouraged to check for recalls or damage to their devices before travelling and to keep their electronics in a protective case or sleeve to prevent damage during the flight.

They can be carried in hand luggage if protected from damage
Lithium batteries are highly susceptible to damage, which can cause them to short circuit, overheat, and even catch fire. This poses a serious safety risk to passengers and crew, especially if the batteries are stored in the cargo hold. To mitigate this risk, the Federal Aviation Administration (FAA) has implemented guidelines for the safe transport of lithium batteries on aircraft.
Passengers are permitted to carry devices containing lithium batteries, such as smartphones, tablets, cameras, and laptops, in their hand luggage. However, it is crucial that these devices are protected from damage and accidental activation during transportation. This can be achieved by keeping them in their original packaging or by placing them in a protective case or sleeve.
Spare lithium batteries, including those used in electronic cigarettes and vaping devices, are also allowed in carry-on baggage. However, passengers must take extra precautions to prevent short circuits. Each battery should be individually protected by keeping them in their original retail packaging or by insulating the battery terminals with tape or a protective case. It is also important to ensure that spare batteries are not transported in quantities exceeding the maximum limit allowed by the airline.
By following these guidelines, passengers can safely transport their lithium-battery-powered devices and spare batteries in their hand luggage. Keeping these items in the cabin ensures that any potential issues, such as overheating or short-circuiting, can be quickly addressed by cabin crew and passengers, reducing the risk of accidents.

Damaged or defective batteries are prohibited in carry-on or checked baggage
Lithium-ion batteries are capable of overheating or short-circuiting, especially if they are damaged. This can lead to a process called thermal runaway, resulting in smoke, fire, and, in some cases, explosions. In the rare event that a lithium-ion battery catches fire, the entire cargo hold could be engulfed in flames.
To reduce the risk of these incidents, the Federal Aviation Administration (FAA) prohibits passengers from carrying damaged, defective, or recalled lithium batteries in their carry-on or checked baggage. This is because damaged or defective batteries are more likely to create sparks or generate dangerous levels of heat. If a battery does begin to smoke or catch fire in the cabin, flight attendants can respond to the issue more quickly than if it were in the cargo hold.
Passengers can protect themselves and others by keeping their electronic devices in a protective sleeve or case. This will prevent the device from being squeezed too hard, which could damage the battery and cause thermal runaway. Additionally, passengers should ensure that their devices are turned off and protected from accidental activation when packed in checked baggage.
It is important to note that different airlines may have specific policies regarding lithium batteries. For example, Southwest Airlines requires that portable chargers remain in plain sight during use, and prohibits charging devices in the overhead bin. Some airlines may also prohibit passengers from using portable batteries altogether during the flight. Therefore, it is recommended to check with the airline for any specific policies or restrictions before travelling with lithium batteries.

Some airlines have implemented policies prohibiting the use of portable batteries during flights
Lithium-ion batteries are capable of overheating or short-circuiting, especially if they are damaged. This can lead to a process called thermal runaway, resulting in smoke, fire, and, in some cases, explosions. While thermal runaway events are rare, they do happen. For example, in November 2024, a cell phone caught fire in the cabin of a plane shortly before takeoff, leading to an evacuation and two injuries.
Due to the risks associated with lithium batteries, some airlines have implemented policies prohibiting the use of portable batteries during flights. For example, Southwest Airlines has a policy that requires passengers to keep portable chargers in plain sight and not in overhead bins. Similarly, several Asian airlines have implemented a ban on using or charging power banks during flights, although they can still be stored in overhead compartments. Other airlines that have implemented similar bans on using and charging power banks during flights include Thai Airways, Singapore Airlines, and Malaysia Airlines.
These policies are in place to ensure the safety of passengers and crew. Lithium batteries, which are commonly found in power banks, can catch fire or explode if they are damaged, overcharged, overheated, or exposed to water. By prohibiting the use of portable batteries during flights, airlines can reduce the risk of fires or explosions occurring onboard.
It is important to note that the policies regarding the use of portable batteries during flights vary among airlines. Passengers should check with their specific airline to understand the policies and requirements before their flight.
