Lithium batteries are allowed in hand luggage, but not checked baggage
Lithium-ion batteries are allowed in hand luggage but not in checked baggage. This is because 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. Federal rules mandate that lithium-ion batteries must be taken out of checked baggage and kept in carry-on luggage or left at home.
Most consumer-type lithium batteries are permitted in hand luggage. However, there are limits to the amount of lithium allowed in each battery. According to government rules, the new lithium quantity limits apply to both spare and installed batteries and are expressed in grams of "equivalent lithium content". Passengers may carry consumer-sized lithium-ion batteries with no more than 8 grams of equivalent lithium content or 100 watt-hours (Wh) of power per battery. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, handheld game, standard laptop computer batteries, or a camcorder battery.
Passengers can also bring up to two larger lithium-ion batteries that each contain between 8 and 25 grams of equivalent lithium content per battery in their carry-on luggage. It is important to note that spare lithium batteries are not allowed in checked baggage. They must be stored in carry-on luggage and protected either in their original packaging or by wrapping them.
Some airlines allow lithium-ion batteries in checked luggage as long as they are installed in a device and are fully powered off. However, it is generally recommended to keep lithium batteries in carry-on baggage. If you are unsure about the specific rules and requirements, it is best to contact the device manufacturer or refer to the official guidelines provided by the relevant aviation authorities.

You can bring batteries in their original packaging or safety pack them
If you're travelling with batteries, you'll want to make sure you're doing so safely and following the correct procedures. The rules around batteries can be a little complicated, so it's always a good idea to check with the specific airport and airline you're flying with. That being said, there are some general guidelines you can follow.
Firstly, it's important to distinguish between the types of batteries you're travelling with. Most consumer-type lithium batteries are usually permitted, while very large, professional batteries may be prohibited. If you're unsure, it's best to contact the device manufacturer or refer to the official guidelines from the U.S. Department of Transportation's SafeTravel website.
Now, when it comes to packing batteries, you have a couple of options. You can bring batteries in their original packaging, which is often the safest and most straightforward method. Alternatively, if you're travelling with loose batteries, you can take some additional safety precautions. Place them in individual sealable plastic bags or use tape to cover the battery terminals, protecting them from short circuits.
It's worth noting that some batteries, like spillable wet cell batteries, are typically not allowed on aircraft. However, if they are part of a passenger's electric wheelchair, they may be permitted with prior notification to the airline. Lithium-ion batteries, including rechargeable lithium, lithium polymer, and LIPO batteries, are generally allowed but with some restrictions. Passengers can carry consumer-sized lithium-ion batteries with no more than 8 grams of equivalent lithium content or 100 watt-hours of power per battery.
Lastly, when it comes to where to pack your batteries, it's recommended to keep them in your carry-on baggage. Spare lithium batteries are typically not allowed in checked luggage due to safety concerns. By keeping them in your carry-on, you can easily access them and ensure they are safely stored throughout the flight. Remember, the TSA may need to physically inspect your baggage, so it's essential to cooperate and have your items easily accessible.

Loose batteries can be put in sealable plastic bags to prevent short circuits
Loose batteries with exposed electrical contacts can cause an explosion and fire during a flight if they come into contact with other metal objects. To prevent this, it is recommended that travellers put loose batteries inside individual sealable plastic bags or use tape to cover the battery terminals. This protective measure ensures that the batteries are safely transported and helps prevent short circuits.
When travelling with batteries, it is important to follow safety guidelines. While most consumer-type lithium batteries are permitted, there are restrictions on certain types of batteries. For example, spillable wet cell batteries, commonly used in cars or motorcycles, are usually prohibited in checked or carry-on baggage. However, these batteries are allowed if they are part of a passenger's electric wheelchair, with prior notification to the airline.
To ensure safety, travellers should also be aware of restrictions on devices powered by lithium-ion batteries, such as hoverboards. Due to incidents of overheating and fires, several major US airlines have banned hoverboards from checked or carry-on baggage. Additionally, the TSA and the Department of Homeland Security have enhanced screening requirements at selected gateway airports in the United States due to security concerns.
It is recommended to keep batteries and related equipment in carry-on baggage rather than checked baggage. In the unlikely event of a battery-related issue, such as overheating, having the batteries accessible in the cabin allows for a quicker response and better management of the situation. Travellers should also consider purchasing batteries from reputable sources and only using batteries approved for their devices.
By following these guidelines and safely packing loose batteries in sealable plastic bags, travellers can help ensure a safe journey for themselves and their fellow passengers.
