What are the precautions for lithium-ion batteries on airplanes

① Carry it with you? Still consign? Neither power banks nor lithium-ion batteries can be checked in. They must be carried on the plane in hand luggage. Because there are more and more accidents caused by rechargeable batteries in recent years, it shows that the design of some rechargeable batteries is not safe enough. Under certain conditions, it may cause sparks or explosions. Therefore, it is not allowed to check lithium ion on any flight. battery. ②Do I have to carry electronic products that cannot be disassembled with lithium-ion batteries? You can clarify the problem in the following two ways: All removable spare batteries and independent lithium-ion batteries, such as those used in mobile phones, cameras, and tablets, should be taken with you as long as they can be removed. b: Lithium-ion batteries that cannot be removed, such as iPhones, MacBooks and other electronic products that cannot be replaced with lithium-ion batteries. In theory, passengers can check these products. However, airport security has the opportunity to conduct additional security checks on the baggage. ③How many lithium-ion batteries can each person carry? Each airline has different regulations, but in general, each airline uses the battery capacity to determine the number of lithium-ion batteries that each passenger can carry. Taking Cathay Pacific as an example, each passenger can only carry 20 spare batteries with a capacity of less than 100 watt-hours (Wh)/2 grams of lithium ion (LC), and a maximum of 2 spare batteries with a capacity between 100Wh and 160Wh. . Large lithium-ion batteries over 160Wh must be declared and transported as cargo in accordance with the International Air Transport Association Dangerous Goods Regulations (IATA Dangerous Goods Regulations) and cannot be carried as luggage. ＊Instructions for carrying lithium-ion batteries on the plane ＊④How to calculate the capacity of spare lithium-ion batteries? Take out your lithium-ion battery, check it, and you will find that mAh and V are usually printed on it. mAh is 'milliampere hour'. We need to convert it to 'watt hour'Wh' lists the battery capacity, but generally batteries use 'mAh' as the battery capacity unit. The calculation method for converting 'mAh' to 'Wh' is as follows: E(Wh)u003dQ(mAh)×V(V)/1000 Calculated by SamsungGALAXYS3 battery, the battery capacity is 2100mAh, and the voltage is 3.8V.
