Lithium batteries

Last updated: 24 Dec 2015

Lithium batteries may be dangerous and can cause fire if not carried properly. Whether a lithium battery can be carried by air or not depends on its configuration and its Watt-hour (Wh) rating (for rechargeable lithium-ion/polymer batteries) or Lithium Content (LC) (for non-rechargeable lithium metal batteries).

Please use the following table to determine if the battery you intend to bring is acceptable:

Ban on hoverboards and other self-balancing scooters

Please note: Effective 9th December, 2015, small vehicles powered by lithium ion batteries are forbidden in passenger checked and cabin baggage.

Important Notes on Lithium Battery:

  1. Please ensure that you have the information available for our staff when requested on the Watt-hour (Wh) or Lithium content (g) for all the installed and spare batteries that you are planning to bring either as carry-on or check-in baggage. Lithium batteries with no or unclear marking of Watt-hour (Wh) rating or Lithium Content (LC) will be refused carriage.
    • Amp-hours (Ah) to Watt-hours (Wh) Conversion: Multiply Ah by Voltage (V), (1Ah = 1,000 mAh), both of these data are displayed on the information plate of the battery.
    • Example: 2.38Ah x 14.4V = 34 Wh for a laptop computer lithium-ion battery
  2. Lithium batteries must be of a type which meets the United Nations (UN) test requirements specified in the UN Manual of Tests and Criteria, Part III Section 38.3.
  3. Equipment/Electronic devices installed with built-in or plug-in lithium batteries such as laptop computers, cameras, mobile phones etc must be switched off with measures to be taken to ensure that they cannot be accidentally activated when placed in check-in baggage.
  4. The maximum number of equipment/electronic devices containing lithium batteries (each within 160Wh or 2g) for carriage in check-in baggage is 10 pieces per passenger, and up to 10 pieces in each bag. For example:
    • 10 pieces per passenger in total (e.g. one passenger checks in two bags)
    • 10 pieces maximum in one bag (e.g. two passengers check in one bag only)
  5. Spare batteries, also called “loose” batteries, are those not installed in equipment. A lithium-ion battery inside your laptop computer is an installed battery. A battery carried separately, as a backup when installed battery runs low, is a spare battery.
  6. Terminals of all spare lithium batteries placed in carry-on baggage must be protected from short circuit by:
    • Enclosing them in their original retail packaging, or
    • Taping over the terminals, or
    • Placing each battery in a separate plastic bag (or protective pouch)
  7. Portable battery charger / Power bank (with built-in lithium batteries) used to recharge the lithium-ion batteries contained in equipment, such as mobile phone, is considered as spare lithium battery.
  8. Non-rechargeable batteries with more than 2 grams of lithium (eg ‘C’ size battery and above) are forbidden in any baggage and must be presented and carried as Cargo in accordance with the .
  9. For US DOT regulations, passengers travelling to and from the US with lithium batteries should visit for details.
  10. Lithium batteries carried in any baggage must conform to the above acceptance criteria. For safety concern, we may refuse further carriage of any excessive and unacceptable batteries upon discovery.
  11. You may be requested by our staff to declare your conformance of the above lithium batteries regulations. It is a criminal offence to make a false statement in response to this question. The offence is punishable on conviction to a fine of HK$ 10,000 and /or imprisonment for up to 6 months and we will inform the Police and airport security services.  Please note that your bags may be searched before and / or after check-in.
  12. Electronic cigarettes cannot be carried in your checked baggage, and must not be used on board our aircraft.
