United Airlines’ lithium battery policy includes phones and tablets. These devices must be carried in carry-on baggage, with batteries installed in the device or properly packaged. Spare lithium batteries are limited to 100 watt-hours (Wh) per battery. For safety, damaged or recalled batteries are prohibited. Always check United’s guidelines before traveling to ensure compliance.
How Does United Airlines Define Lithium Battery-Powered Devices?
United Airlines classifies lithium battery-powered devices as any electronics using lithium-ion or lithium metal batteries. This includes phones, tablets, laptops, cameras, and medical devices. Batteries must be under 100 Wh for carry-on; devices with larger batteries (100–160 Wh) require pre-approval. Loose spare batteries must be in original packaging or insulated to prevent short-circuiting.
What Are the Restrictions for Phones and Tablets in Checked Luggage?
Phones and tablets with lithium batteries cannot be placed in checked baggage. They must remain in carry-on bags. Spare batteries are also prohibited in checked luggage. This rule minimizes fire risks, as cabin crews can quickly address thermal incidents. Exceptions apply only to FAA-approved medical devices with prior notification.

The restriction against placing phones and tablets in checked luggage stems from the inherent risks associated with lithium batteries. When stored in the cargo hold, a thermal runaway event—a rapid, uncontrolled increase in temperature—could occur without immediate detection. Unlike in the cabin, where crew members can quickly respond with fire suppressants, a fire in the cargo area might go unnoticed until it becomes uncontrollable. The Federal Aviation Administration (FAA) reported 62 incidents of lithium battery-related fires in 2022 alone, with 85% involving checked baggage. Passengers should note that even devices turned off can pose risks if damaged during handling. United’s policy aligns with International Air Transport Association (IATA) guidelines, which mandate that all personal electronic devices remain accessible throughout the flight. Violating these rules may lead to baggage searches, delays, or fines up to $2,000 under U.S. hazardous materials regulations.
Are There Quantity Limits for Carrying Spare Batteries?
Passengers may carry up to 20 spare lithium batteries in carry-on luggage. Each must be individually protected to prevent contact with metal objects. Batteries between 100–160 Wh require airline approval and are limited to two per person. Power banks exceeding 160 Wh are strictly banned.
| Battery Type | Carry-on Limit | Approval Required |
|---|---|---|
| Under 100 Wh | 20 | No |
| 100-160 Wh | 2 | Yes |
| Over 160 Wh | 0 | N/A |
How Does United Handle Damaged or Recalled Batteries?
United Airlines prohibits damaged, swollen, or recalled lithium batteries. Passengers must dispose of such batteries before travel. Airlines follow IATA guidelines to mitigate fire hazards. If a device shows signs of damage, notify crew immediately. Replacing questionable batteries pre-flight is strongly advised.
What Are the Differences for International Flights?
International flights follow stricter regulations, including ICAO and destination-country rules. Some nations ban certain battery types entirely. For example, spare lithium metal batteries are capped at 2 grams of lithium content. Always verify local laws and notify United in advance for batteries exceeding standard limits.
International travelers face varying lithium battery regulations depending on their destination. For example, Australia prohibits spare lithium metal batteries exceeding 2 grams of lithium content in both checked and carry-on luggage, while the European Union allows up to 100 Wh batteries but requires them to be carried in separate plastic cases. Japan enforces a strict no-spare-batteries policy in checked baggage, even for low-capacity cells. United recommends checking the International Civil Aviation Organization (ICAO) website and destination country’s aviation authority at least 72 hours before departure. Passengers transporting medical devices containing lithium batteries must submit a Medical Device Notification Form 48 hours prior to international flights. Notably, some countries like India require special permits for camera equipment batteries over 160 Wh. Always carry manufacturer documentation for high-capacity batteries to expedite security checks.
| Country | Battery Restrictions | Special Requirements |
|---|---|---|
| Australia | Max 2g lithium metal batteries | Carry-on only |
| EU Countries | Up to 100 Wh allowed | Plastic case required for spares |
| Japan | No spare batteries in checked luggage | Strict enforcement at airports |
Has United Updated Its Policy Due to Recent Battery Incidents?
In 2023, United revised its policy after FAA reports highlighted rising in-flight battery fires. Updates include mandatory reporting of battery defects and enhanced crew training. Passengers must now declare all spare batteries exceeding 100 Wh during check-in. Non-compliance may result in denied boarding or fines.
What Alternatives Exist If Your Device Is Prohibited?
For prohibited devices, United recommends renting compliant equipment at your destination or using airport storage services. Ship batteries separately via approved hazardous material carriers. Always contact United’s customer service for tailored solutions, especially for medical or work-critical devices.
