What You'll Learn

Battery types allowed in carry-on baggage
Passengers can carry most batteries and portable electronic devices in their carry-on baggage. This includes common devices such as laptops, cell phones, vaping devices, and mobility aids. However, there are specific guidelines for different types of batteries.
Dry cell alkaline batteries, such as AA, AAA, C, D, and 9-volt batteries, are typically allowed in carry-on baggage. Dry cell rechargeable batteries like Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCad) batteries are also permitted. It is recommended to keep these batteries in their original packaging to avoid raising suspicion.
Lithium-ion batteries, also known as rechargeable lithium, lithium polymer, LIPO, or secondary lithium, are allowed in carry-on baggage but with certain restrictions. Lithium-ion batteries with a watt-hour (Wh) rating between 0 and 100 Wh are permitted, while those between 101 and 160 Wh require air carrier approval. Lithium-ion batteries exceeding 160 Wh are prohibited from carriage on passenger aircraft. It is important to note that lithium-ion batteries not installed in a device (spares) must be individually protected to prevent short circuits and are typically limited to two spares per person.
Fuel cell systems containing fuel and fuel cell cartridges, including spare cartridges, are permitted in carry-on baggage only. These cartridges must be marked with the wording "APPROVED FOR CARRIAGE IN AIRCRAFT CABIN ONLY." Gasoline-powered equipment is only allowed if it is new, in its original packaging, and has never been opened.
Additionally, passengers are advised to secure battery chargers in their carry-on or checked bags. If a charger has an electrical cord, it should be wrapped tightly around the charger to avoid any potential safety hazards.

Battery packing tips
When packing for a flight, it is important to consider the types of batteries you are bringing and how to pack them safely. Here are some detailed tips to help you safely pack your batteries:
Know the Types of Allowed Batteries
First, it is essential to know which batteries are allowed in carry-on and checked baggage. Dry cell alkaline batteries, such as AA, AAA, C, D, 9-volt, and button-sized cells, are typically permitted. Dry cell rechargeable batteries like Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCad) are also allowed. Lithium-ion batteries, often used in consumer electronics like laptops and cell phones, are generally accepted but with restrictions.
Packing Tips for Lithium-Ion Batteries
Spare lithium-ion batteries, including power banks and cell phone charging cases, must be carried in carry-on baggage only. Each airport's security staff is trained to identify safety issues with batteries, so they must be packed properly. When bringing lithium-ion batteries, consider the following:
- Place each battery in its own protective case, plastic bag, or package to isolate the terminals and prevent short-circuiting.
- Cover the battery terminals with tape.
- Keep them in their original retail packaging, if possible.
- Ensure they are securely taped and not loose.
Other Battery-Powered Devices
If you are travelling with battery-powered devices, such as scooters or wheelchairs, you must inform the aircraft operator so they can be properly packaged for air travel. Additionally, if you are carrying electronic devices with batteries in your luggage, tape the power switch in the "off" position to prevent them from accidentally turning on during the flight.
Prohibited Batteries
It is important to note that some batteries are prohibited from being transported on airplanes. Car batteries, wet batteries, spillable batteries, and damaged/recalled batteries are not allowed in carry-on or checked baggage unless they are powering a scooter or wheelchair.
By following these tips and staying informed about battery safety guidelines, you can ensure a smooth travel experience and help prevent any fire-related incidents.

Getting TSA pre-check
TSA PreCheck is an expedited security initiative designed to help travellers move through the airport with greater convenience and less friction. Passengers with TSA PreCheck can often move through security much faster than those without, with 99% waiting less than 10 minutes, and many less than 5 minutes. TSA PreCheck passengers do not need to remove their shoes, laptops, 3-1-1 liquids, belts, or light jackets.
To apply for TSA PreCheck, you must be a United States citizen or permanent resident, and you must not have a criminal record. The application process involves the following steps:
- Fill out an online application form, which typically takes less than 5 minutes.
- Pay a $78 application fee.
- Make an appointment for a 10-minute in-person background check, during which you will hand over your documents for review, have your fingerprints taken, and possibly verify some of the information you provided.
- If approved, enjoy TSA PreCheck benefits for 5 years.
You may increase your likelihood of being selected for PreCheck by signing up for a Customs and Border Protection (CBP) Trusted Traveler Program, including Global Entry, SENTRI, and NEXUS, or by completing the PreCheck application program at a TSA Application Center. Several other government programs, such as CLEAR, offer TSA PreCheck without going through the standard application process, though you will generally be required to undergo another application process for a federal trusted travellers program.

Battery safety and security threats
Batteries are a common item that people need to bring when travelling by plane, whether they are for cameras, personal electronics, or other battery-operated equipment. However, batteries can pose safety and security threats. Here are some guidelines to ensure battery safety and address security threats:
Battery Safety
- Avoid bringing metal into contact with batteries. Metal conducts electricity, so anyone touching a metal object as it comes into contact with a battery risks electrocution.
- Never allow both terminals to make contact with an item (especially yourself) simultaneously. When both terminals are engaged, an electrical current will pass through anything touching them.
- Do not hand-guide batteries during the lifting/moving process. Touching the battery can lead to electrical shock or bring the handler into contact with corrosive battery acid.
- Wear protective equipment when handling batteries, including gloves, eyewear, and a hard hat. Gloves and protective eye gear guard against battery acid, while a hard hat is important during the lifting process in case a battery falls.
- Do not store batteries in direct contact with other batteries.
- Store batteries in a dry, cool location with stable temperatures, away from direct sunlight.
- Dispose of batteries appropriately.
Security Threats
The Federal Aviation Administration (FAA) has implemented safety guidelines for batteries being transported on airplanes to prevent fire-related incidents. TSA security officers are trained to identify potential safety and security battery-related threats in carry-on and checked bags. Here are some tips to avoid security issues when travelling with batteries:
- Tape up and secure loose batteries.
- Place each battery in its own protective case, plastic bag, or package, or place tape across the battery's contact points.
- Put batteries in their original box.
- Get a media badge if you are a professional photographer or videographer.
