Lithium Batteries


Lithium batteries have become such a common, everyday item that they have been taken for granted by consumers, with little thought given to the precautions that need to be taken to ensure lithium batteries do not pose a hazard in air transport. This issue can present itself either in passenger baggage but even more so in air cargo.

Lithium batteries are defined as dangerous goods by the United Nations, which specifies the very stringent manufacturing and testing requirements the batteries must meet. Specific requirements to ensure that they can be carried safely by air in both cargo and baggage are determined by ICAO (International Civil Aviation Organisation) and these are then reflected in IATA’s Dangerous Goods Regulations.

Lithium metal batteries

Sometimes referred to as ‘primary’ batteries, lithium metal batteries are typically non-rechargeable and used in long-life applications such as watches, calculators and emergency locator beacons. The term lithium metal encompasses lithium alloy batteries and includes those containing sulfuryl chloride and thionyl chloride.

Lithium ion batteries

Sometimes referred to ‘secondary’ batteries, lithium ion batteries are rechargeable and used in consumer electronics such as mobile phones and laptop computers and in larger applications such as e-bikes and motor vehicles. The term lithium ion includes lithium polymer and lithium iron phosphate batteries.

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: 

Watt-hour Rating (Wh) or (Li Content)



Carry-on Baggage

Checked Baggage

Operator Approval


≤100Wh (2g)



Small lithium batteries and cells for mobile phones, cameras, watches, portable music players, most original laptop computers, etc





   Mob. phone



Video camera



Spare             batteries



In equipment






Spare batteries(these batteries must be individually packed to prevent short circuit)










(no limit)


Yes (but recommended to put in carry-on baggage)

















>100 to≤    160 Wh


















Medium lithium batteries and cells include extended life batteries for laptop computers, and batteries used by audiovisual professionals. Lithium metal batteries with a lithium content exceeding 2g but not exceeding 8g.




Commercial camera and video equipment

Portable medical equipment





In equipment







Spare batteries









Yes (two   pieces per passenger)


 Yes (but recommended to put in carry-on baggage) 
















>160 Wh 


Large lithium batteries and cells primarily for equipment used in industry, and may be found in some electric and hybrid vehicles, mobility devices, scooters, etc



  Electric bicycle

Electric segway



Forbidden in any baggage

Must be presented and carried as Cargo in accordance with the IATA Dangerous Goods Regulations

For lithium-ion battery powered wheelchairs or other similar mobility aids for use by passengers whose mobility is restricted by a disability, health/age, or a temporary mobility problem (eg broken leg), please contact our reservations office for assistance.




>300 Wh 












Battery-powered wheelchairs/ mobility aids with lithium ion batteries (collapsible), lithium ion battery must be removed and carried in the cabin. It is recommended that passengers make advance arrangements with each operator.




Battery operated     wheelchair



                                    Mobility Aid



In equipment









   Spare batteries


Yes( battery must not exceed 300Wh, or for a device that is fitted with 2 batteries , each battery must not exceed 160Wh)


A max. of one spare battery not exceeding 300Wh or two spares not exceeding 160Wh may be carried

























Electronic cigarettes are also called ‘personal vaporizers’ or ‘electronic nicotine delivery system’ are battery powered devices which can cause overheating through the accidental activation of their heating elements resulting in fires.

 Important Notes on Lithium Battery:

  • 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

          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.

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.

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.

          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)

          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.

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 IATA Dangerous Goods Regulations.

For US DOT regulations, passengers travelling to and from the US with lithium batteries should visit for details.

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.

A person guilty of an offence under subarticle (1) of The Airport and Civil Aviation (Security) Act shall be liable, on conviction, to a fine (multa) or to imprisonment for a term not exceeding two years or to both such fine and imprisonment.           

Electronic cigarettes cannot be carried in your checked baggage, and must not be used on board our aircraft.
