The Civil Aviation Administration of China has made clear regulations for passengers to carry lithium batteries by plane:
First, passengers are not allowed to carry lithium batteries in their checked baggage.
Second, passengers can carry lithium-ion batteries or consumer electronic equipment (watches, calculators, cameras, mobile phones, laptops, cameras, etc.). ) for personal use. Spare batteries must be protected separately to prevent short circuit, and can only be carried in hand luggage. In addition, each spare battery shall not exceed the following quantities: lithium metal or lithium alloy batteries, and the lithium content shall not exceed 2g; For lithium-ion batteries, the total content of lithium does not exceed100g.
Third, passengers can carry lithium-ion batteries with the same total lithium content of more than 8 grams but not more than 25 grams. If a single battery is well protected against short circuit, it can be carried in hand luggage. Spare batteries are limited to 2 per person.
Fourth, other types of spare dry batteries, such as Ni-MH batteries, can also be carried around if short-circuit prevention measures are taken.
Extended data:
Lithium-ion batteries with a total lithium content of more than 25g should be transported by cargo according to the Air Transport Standard for Lithium Batteries (MH/T 1020-2007).
Reasons for prohibiting consignment:?
Aircraft are forbidden to consign lithium batteries, because the temperature in the cargo hold of aircraft is high and lithium batteries are easy to catch fire. But lithium batteries can be put in hand luggage according to the prescribed limit, because hand luggage is located in the cabin and the temperature is not that high. In addition, if the hand luggage catches fire, find it and put it out at the first time, so as not to cause more harm.
