Lithium Batteries

How your lithium batteries are stored and their watt-hour (Wh) ratings determines whether or not they may travel by air.  Use the following guide to help you find out if your batteries are accepted on Singapore Airlines and SilkAir flights:

*Watt hours (Wh) = Amp hours (Ah) x Voltage (V) 
All batteries & battery-powered devices carried must be for personal use (not for resale or distribution by a vendor)

Carriage of Baggage Powered by Lithium Batteries

Baggage powered by lithium batteries (commonly known as “Smart Baggage”) may include motors, power banks, GPS, GSM, Bluetooth, RFID or Wi-Fi technology. 

All current requirements on the carriage of lithium batteries will apply to the carriage of “Smart Baggage”.

In addition, the following requirements must be fulfilled for the “Smart Baggage” to be accepted as: 

A. Cabin baggage:

  • Lithium battery must not exceed 160 Wh.
  • Lithium battery must be removable but may remain installed in the device.
  • The baggage must be within cabin baggage allowance.
  • All transmitting functions (example: Bluetooth, Wi-Fi) must comply with the PED restrictions in the onboard Passenger Safety Information Card.



B. Check-in baggage: 

  • Lithium battery must be removed and carried into the cabin.
  • Lithium battery must not exceed 160 Wh.
  • Each passenger can carry a maximum of 2 spare lithium batteries of 100-160Wh into the cabin.



If the "Smart Baggage" does not meet the above safety requirements, it will be refused at check-in. It will be the passenger's responsibility to arrange for the storage or disposal of such items prior to boarding.
