Can You Bring a Lithium Ion Battery on a Plane?

Lithium-ion (Li-ion) batteries have become a staple in modern technology, powering everything from smartphones and laptops to electric vehicles and cameras. However, when it comes to traveling, especially by plane, lithium-ion batteries can pose a safety risk. This has led to strict regulations regarding the transportation of these batteries. In this article, we will explore the rules and guidelines for bringing lithium-ion batteries on a plane, and provide essential safety tips to ensure that your battery does not cause any issues during your flight.

Why Are Lithium-Ion Batteries Regulated on Planes?

The primary reason lithium-ion batteries are regulated by airlines is due to their potential to overheat and cause fires. In rare cases, lithium-ion batteries can undergo a phenomenon called thermal runaway, in which the battery's internal temperature rises uncontrollably. This can lead to a fire or explosion, which poses a significant risk to aircraft safety. As a result, the International Air Transport Association (IATA) and various national aviation authorities have established rules to minimize this risk.

While these events are extremely rare, airlines and regulators take the safety of passengers and crew seriously, leading to the implementation of specific guidelines for transporting lithium-ion batteries.

Can You Bring Lithium-Ion Batteries on a Plane?

In short, yes, you can bring lithium-ion batteries on a plane, but there are specific guidelines you must follow. These guidelines vary depending on the size of the battery and whether it's installed in a device or being carried separately.

1. Lithium-Ion Batteries in Electronic Devices (Phones, Laptops, Cameras, etc.)

Generally Allowed in Carry-On Luggage: Most lithium-ion batteries installed in personal electronic devices (such as smartphones, laptops, and cameras) are allowed in your carry-on luggage. The Federal Aviation Administration (FAA) and other international aviation authorities recommend packing devices with lithium-ion batteries in your carry-on bag rather than checked luggage, as this allows for quicker access in case of a fire.
Size Limits: Airlines impose restrictions on the size of the lithium-ion battery you're allowed to carry. These restrictions are based on the battery's watt-hour (Wh) rating:
- Batteries up to 100 Wh: Lithium-ion batteries up to 100 watt-hours are generally allowed in carry-on luggage without any special requirements.
- Batteries between 100 Wh and 300 Wh: Batteries with a capacity between 100 and 300 Wh, such as those used in larger laptops or camera equipment, are typically allowed in carry-on luggage, but may require approval from the airline. There may also be limits on the number of batteries you can carry.
- Batteries over 300 Wh: Batteries exceeding 300 Wh (typically found in large devices like electric vehicles or medical equipment) are not allowed in passenger aircraft cabins or in checked luggage. Special arrangements and approvals are required for transporting these types of batteries.
Power Banks: Power banks, which are portable external chargers, are also subject to these guidelines. Power banks typically fall under the same watt-hour restrictions, so you will need to ensure that they do not exceed the allowed limits. Additionally, many airlines limit the number of power banks you can carry.

2. Lithium-Ion Batteries in Checked Luggage

Batteries Installed in Devices: If the lithium-ion battery is installed in a device (such as a smartphone or tablet), it is generally allowed in checked luggage. However, as mentioned earlier, carrying lithium-ion batteries in your carry-on is preferred in case of emergencies.
Loose Batteries: Loose lithium-ion batteries (batteries that are not installed in a device) are not allowed in checked luggage. This includes spare batteries for devices like cameras or laptops. Loose batteries pose a significant fire risk, so they must be carried in your carry-on baggage.
Proper Packaging for Spare Batteries: If you need to carry spare lithium-ion batteries (i.e., loose batteries), they must be stored in their original packaging or in a plastic bag to prevent contact with other metallic objects, which could cause a short circuit. Some airlines also require that the battery terminals be covered with tape to further reduce the risk of short-circuiting.

3. Airline-Specific Rules and Recommendations

Different airlines may have slightly varying policies, so it’s always a good idea to check the specific rules of the airline you’re flying with before your trip. Some airlines may have more stringent rules regarding the size and number of lithium-ion batteries you can bring onboard. For example, some may limit the total number of batteries you can carry in your carry-on luggage, while others may have special procedures for transporting batteries over 100 Wh.

4. International Travel Considerations

When traveling internationally, it's important to be aware that lithium-ion battery regulations can vary by country. While the IATA provides guidelines that are generally followed worldwide, some countries may have additional restrictions or requirements for lithium-ion batteries. Always check the customs and aviation regulations of the countries you will be traveling to and from to ensure compliance.

Safety Tips for Traveling with Lithium-Ion Batteries

To ensure safe travel with lithium-ion batteries, follow these additional tips:

Keep Batteries in Original Packaging: If possible, keep spare lithium-ion batteries in their original packaging. If the packaging is not available, store them in a protective case or plastic bag to prevent contact with metal objects.
Avoid Overcharging Before the Flight: Make sure your electronic devices are charged to around 50% before the flight. Avoid overcharging devices immediately before your trip, as fully charged batteries may be more prone to overheating.
Monitor Devices During the Flight: If your device starts to overheat, emit a burning smell, or show any signs of distress, immediately inform the flight attendants. Many airlines have safety protocols in place to handle battery-related incidents.
Don’t Use Damaged Batteries: If your lithium-ion battery is damaged, swollen, or leaking, do not attempt to bring it on the plane. Discard it properly by taking it to a certified battery disposal or recycling center.

What to Do If a Lithium-Ion Battery Catches Fire on a Plane

Though extremely rare, a lithium-ion battery fire can occur in-flight. If you ever experience a battery fire on a plane, follow these steps:

Notify the Crew: Alert the flight attendants immediately. They are trained to handle emergencies, including battery fires.
Use the Appropriate Fire Extinguisher: Flight attendants have special fire extinguishers designed to handle lithium-ion battery fires.
Follow Crew Instructions: In the unlikely event of a lithium-ion battery fire, the flight crew will provide instructions. Always follow their guidance.

Conclusion

Lithium-ion batteries are allowed on planes, but strict regulations are in place to ensure safety. While carrying lithium-ion batteries in your carry-on is generally recommended, it's crucial to understand and follow the airline’s guidelines regarding battery size, watt-hour ratings, and proper packaging. By taking the necessary precautions, you can travel safely and avoid any risks associated with lithium-ion batteries during your flight.
