Notice on Safe Transportation of Lithium Batteries
1、 Passengers or crew members should carry portable electronic devices (watches, calculators, cameras, mobile phones, laptops, camcorders, etc.) containing lithium or lithium-ion battery cells or batteries for personal use as hand luggage on board, and the lithium content of lithium metal batteries should not exceed 2 grams, and the rated energy value of lithium-ion batteries should not exceed 100 Wh (watt hours). Items exceeding 100Wh but not exceeding 160Wh can be loaded onto equipment in checked baggage or hand luggage with the approval of the airline. Lithium batteries exceeding 160Wh are strictly prohibited from being carried.
2、 The backup battery of portable electronic devices must be individually protected against short circuits (by placing it in the original retail packaging or insulating the electrodes in other ways, such as applying tape to exposed electrodes, or placing each battery in a separate plastic bag or protective box), and can only be carried in carry on luggage. Only two backup lithium batteries with a capacity of 100-160Wh approved by the airline can be carried.
3、 Passengers and crew members carrying lithium-ion battery powered wheelchairs or other similar means of transportation, as well as portable medical electronic devices containing lithium metal or lithium-ion battery cells or batteries carried by passengers for medical purposes, must carry them in accordance with the transport and packaging requirements of the International Civil Aviation Organization's Technical Regulations for the Safe Transport of Dangerous Goods by Air and obtain approval from the airline.
4、 The calculation method for the rated energy of lithium batteries: The unit of rated energy is watt hours Wh, and the calculation method is to multiply the rated capacity of the battery cell or battery (in ampere hours Ah) by the nominal voltage (in volts V). Example: If the rated capacity of a certain brand of mobile phone lithium battery is 1650mAh and the nominal voltage is 3.8V, then the rated energy is 1.65 times; 3.8=6.7Wh。
