Prohibited or Restricted Items

Battery or Fuel-Powered

For the safety of all passengers, we have strict guidelines about battery and fuel-powered items that are permitted aboard a Delta aircraft. Please review the following guidelines before coming on board.


Guidelines for fuel cell systems:

  • Portable electronic devices (i.e. cameras, cellular phones, laptop computers and camcorders) powered by fuel cell systems, and not more than two spare fuel cell cartridges per passenger, are allowed when transported in carry-on baggage
  • No more than two spare fuel cell cartridges maybe carried by a passenger.
  • Fuel cell systems containing fuel and fuel cell cartridges, including spare cartridges are permitted in carry-on baggage only
  • Fuel cell cartridges may not be refillable by the user. Refueling the fuel cell systems is not permitted, except that the installation of a spare cartridge is allowed
  • Each fuel cell cartridge and system must be durably marked by the manufacturer with the wording: "APPROVED FOR CARRIAGE IN AIRCRAFT CABIN ONLY"


Gasoline-powered equipment, such as chainsaws and lawn equipment, is only allowed if it's new and in its original packaging and has never been opened. You may not check gasoline or any other flammable fuel to power the device.


Lithium cells or batteries power many consumer electronic devices and medical devices, like watches, laptop batteries, calculators, cell phones, hearing aids and much more. You can bring lithium-battery powered devices as carry-on items or in checked baggage.  Spare lithium batteries are allowed as carry-on items only with batteries individually protected to prevent short circuit.


Tips to properly transport spare lithium batteries:

  • Pack spare batteries in carry-on baggage.
  • Keep spare batteries in the original retail packaging to prevent unintentional activation or short-circuiting.
  • If original packaging is not available, effectively insulate battery terminals by isolating spare batteries from contact with other batteries and/or metal.
  • Specifically, place each battery in its own protective case, plastic bag or package, or place tape across the battery's contacts to isolate terminals.
  • Take steps to prevent crushing, puncturing, or putting a high degree of pressure on the battery, as this can cause an internal short circuit, resulting in overheating.

Size Limits for Lithium Batteries:

Passengers are permitted to travel with lithium ion batteries that contain a maximum of 160-watt hours per battery.  Any lithium ion battery containing more than 160-watt hours is prohibited from carriage on all passenger aircraft. Lithium ion batteries installed in a personal electronic device can be transported as checked or carry-on baggage. Lithium ion batteries not installed in a device (spares) must be in carry-on baggage and no more than two (2) spares between 100 and 160-watt hours are allowed.

Quantity Limits for Lithium Batteries:

Each person is limited to a maximum of 20 spare batteries.

For more information on dangerous goods, visit the FAA's Pack Safe page and TSA What Can I Bring page. Damaged, defective or recalled lithium batteries must not be carried in carry-on or checked baggage. Additional information concerning recalled consumer batteries and battery systems may be located on the Consumer Product Safety Commission website.
