What is the current battery limits in airline baggages while taking a flight in China?
The current regulation on lithium batteries in airline baggage in China is issued in 2011 by Civil Aviation Administration of China in the “Notice on Strengthening of Safety of Lithium Batteries In Passenger Baggage In Air Transport” ( No.1888), which requires the adherence with the ICAO “Safe Transport of Dangerous Goods Technical Rules” (2011-2012 edition) with the following provisions:
Passengers’ or crew members’ personal lithium or lithium ion cells or batteries for portable electronic devices (watches, calculators, cameras, mobile phones, laptop computers, camcorders, etc.) should be carried as hand baggage, and the lithium contained shall not be more than 2 grams and the lithium-ion battery energy value shall not exceed 100Wh (Watt-hour, Wh= V x mAh/1,000). For those ranged between 100Wh and 160Wh, they can be hand carried with approval of the airlines. Lithium battery with energy value exceeding 160Wh is forbidden to be carried as luggage in flights in China.
Generally speaking, mobile phone’s battery energy value is rated between 3 to 10Wh; SLR camera battery energy is 10-20Wh; camcorder battery energy is 20-40Wh; laptop battery energy is 30-100Wh. Therefore, energy value of batteries for most mobile phones, camcorders, SLR cameras and laptop computers and other electronic equipments will not exceed the limit of 100Wh.
Battery Energy Value Calculation
The lithium battery nominal voltage is 3.7V, nominal capacity is 760mAh,
760 mAh / 1000 = 0.76Ah
The watt hours (wh) = 3.7V × 0.76Ah = 2.9Wh
