Rechargeable batteries need to check in?

There are three points:1. Passengers are not allowed to carry lithium batteries in checked baggage.2. Portable electronic devices (watches, calculators, cameras, cell phones, laptops, video cameras, etc.). Items containing lithium or lithium-ion batteries for personal use should be carried on board as hand baggage, lithium metal batteries containing lithium shall not exceed 2g, lithium-ion batteries rated energy value shall not exceed 100wh (watt-hour). Those exceeding 100wh but not exceeding 160wh must be declared to the airline, and can be placed on the equipment in the checked baggage or hand baggage after approval by the airline. Lithium batteries over 160wh are strictly prohibited.3. Spare batteries for portable electronic devices must be individually short-circuit protected (placed in the original retail packaging or otherwise insulated from the electrodes, such as taping over exposed electrodes, or placing each battery in a separate plastic bag or protective case) and may only be carried in hand baggage. Only two airline-approved 100-160Wh spare batteries can be carried. Can I check-in rechargeable batteriesYou can carry rechargeable batteries on board the airplane, but you must comply with the relevant regulations of the Civil Aviation Administration of China (CAAC) and the airlines. Specific regulations are as follows: According to the current valid ICAO "Technical Rules for the Safe Transport of Dangerous Goods by Air" and "Regulations on the Administration of Transportation of Dangerous Goods by Civil Aviation of China", passengers carrying "rechargeable batteries" should comply with the following regulations: 1. The charging treasure must be carried by passengers for their own use. Charging treasure" can only be carried in hand luggage or carry-on, and is strictly prohibited to be carried in checked baggage. The rated energy of "rechargeable treasure" does not exceed 100Wh without the approval of the airlines; the rated energy exceeds 100Wh but does not exceed 160Wh, and can be carried only with the approval of the airlines, but each passenger is not allowed to carry more than two "rechargeable treasures". Fourth, it is strictly prohibited to carry a "rechargeable treasure" with a rated energy of more than 160Wh; it is strictly prohibited to carry a "rechargeable treasure" without a rated energy indicated, or without other labeled parameters to calculate the rated energy. 5. Don't use a "rechargeable treasure" to charge electronic devices during a flight. Do not use the "rechargeable battery" to charge electronic devices during the flight. For rechargeable batteries with an activation switch, the rechargeable batteries should always be turned off during the flight. I don't know how to manage my rechargeable battery when I fly. Lithium battery devices such as rechargeable batteries must be carried in the cabin. As lithium batteries are encapsulated in a pressure relief method, originally to ensure safety, but in the high-altitude, low-pressure environment, the consequences of bursting and burning occurred. The civil aviation authorities have therefore stipulated that lithium battery equipment must be carried into the cabin by passengers because the cabin is pressurized. In addition, it is stipulated that the lithium content of lithium metal batteries must not exceed 2g, and the rated energy value of lithium-ion must not exceed 100Wh (watt-hours). Those exceeding 100 watt-hours but not exceeding 160 watt-hours may be installed in equipment in checked or hand baggage with the consent of the airline. Lithium batteries exceeding 160 watt-hours are strictly prohibited. Lithium batteries should be labeled with a brand specification model that meets the national standard. According to this standard, at least ten cell phone batteries can be carried. So although passengers carry the necessary cell phones, computers, rechargeable batteries, cameras and other devices and spare batteries, they will still take them out for manual inspection by security personnel during the security check. You can take it on the airplane why I can not check the rechargeable treasure, but can carry not only the rechargeable treasure, separate lithium batteries can not be checked. If lithium batteries are installed in equipment (such as cameras, camcorders, laptops, cell phone batteries, etc.). , they can be checked in with the device. Once the two are separated, the individual lithium batteries can be carried on when their capacity meets the range. If it is out of range, approval is also required. Rechargeable batteries are spare lithium batteries, which can easily cause spontaneous combustion when heated at high altitude. If the lithium battery is put directly into the baggage, the baggage is squeezed and collided in the narrow cargo hold, it is likely to catch fire and explode, and the fire in the cargo hold is difficult to be found and controlled, so checking lithium batteries is very dangerous. What kind of rechargeable treasure only can not be consigned to carry-on?100Wh (including) the following rated energy in line with the norms; rated energy greater than 100Wh less than or equal to 160Wh, need to apply for approval in advance to the check-in counter, issued after the approval of the release of the single per person can carry on up to two; if the rated energy of more than 160Wh, then can not pass the security check. Even rechargeable treasure that meets the requirements can't be checked in and can only be carried with you. Count the capacity of your rechargeable treasure or lithium battery before you leave home, because it is dangerous goods, the airport will not give temporary storage. If you bring a mobile power that does not meet the specifications, you will end up throwing it away. Can I check my rechargeable battery? No. In August 2014, CAAC issued the "Announcement on the Regulations on Civil Aviation Passengers Carrying "Charging Bowls" on Flights", which for the first time specifically emphasized the regulations on civil aviation passengers carrying charging bowls on flights, and specifically highlighted the risks of charging bowls. The Announcement shows that in the future, when passengers take the airplane, can only carry rated energy within 160 watt hours of rechargeable treasure, belonging to the "three-free" products of rechargeable treasure is prohibited, prohibited consignment of rechargeable treasure. Rechargeable treasure is actually lithium batteries, easy to spontaneous combustion. In the past few years, there are many passengers at home and abroad on the flight smoking fire consignment lithium battery cases. A civil aviation industry insiders said: "rechargeable treasure in the bumps and other cargo collision, it is easy to appear this problem. Extended information:Charging treasure rated energy to determine the method:If the charging treasure is not directly labeled rated energy Wh (watt-hour), charging treasure rated energy can be converted in the following way:1. If the nominal voltage (V) and nominal capacity of the charging treasure is known (Ah), you can get the value of the rated energy by calculating:Wh = VxAh, usually in the charging treasure labeled nominal voltage and capacity.
