Lithium Batteries

As you probably know, traveling with consumer electronic and medical devices containing lithium cells or batteries (e.g. watches, calculators, cameras, cell phones, laptops, camcorders, hearing aids, etc.) is allowed onboard as carry-on. Spare lithium batteries are allowed as carry-on only, and must be individually protected to prevent short circuits.

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.
