Can be checked in, check your laptop during the flight. Domestic airlines do not prohibit the inspection of laptops. It should be noted that laptops are valuable items. Airports and airlines will not be responsible for lost or damaged computers, so if you need to save them, you need to protect them. .
1. Airlines have size and weight restrictions. Each person can bring one object, the volume of which does not exceed 20 x 40 x 55 cm and the weight does not exceed 5 kg. First class passengers can carry two pieces of 5 kg baggage
2 According to the “Air Transport Notice on Enhancing the Safety of Lithium Batteries in Passenger Baggage” (Bureau [2011] n ° 30) published by other departments. of the Civil Aviation Administration. Electricity requirements invented in 1888): Batteriesor lithium or lithium-ion batteries intended for personal use by passengers or crew members of portable electronic devices (watches, calculators, cameras, cell phones, laptops, video cameras, etc.) must be carried on board. the plane as hand luggage.
3. In summary, laptops can be registered, but lithium batteries can only be taken with you. Therefore, if you want to check your laptop, you need to remove the lithium battery from the laptop and take it with you.
Detailed information:
According to the ICAO “Technical Instructions for the Safe Transport of Dangerous Goods by Air” (2011-2012 edition), passengers or members of crew may contain lithium or lithium ions. for personal use.Portable electronic devices equipped with batteries or batteries (watches, calculators, cameras, mobile phones, laptops, camcorders, etc.) must be carried on board as carry-on baggage.
In addition, the lithium content of lithium metal batteries should not exceed 2 grams, the rated energy value of lithium-ion batteries should not exceed 100 wh (watt hours), and those exceeding 100 wh but not exceeding 160 Wh may be charged during inspection Baggage equipment or carry-on baggage approved by the airline. Lithium batteries exceeding 160Wh are prohibited.
There are two reasons why lithium batteries cannot be verified by air:
1. The lithium contained in lithium batteries is an extremely unstable metal. is in the cabin, it is likely to be squeezed and collided, which can easily cause spontaneous ignitionof the lithium battery, seriously threatening aviation safety.
2. Lithium batteries can guarantee their safety under normal use, but if they experience aging, short circuit, high current discharge, high temperature environment, etc., they may ignite or explode spontaneously. Reports, generally speaking, lower quality lithium batteries with cut corners are more likely to have problems.

< p>Baidu Encyclopedia - Lithium-Ion Battery TransportationAre all laptop batteries lithium batteries? Otherwise, is it okay if it's a laptop with a lithium battery?
1. Pay attention to the cycle cycle of the baNote: The number of cycles, not the number of charges, is directly related to the life of the lithium battery. This number of cycles refers to one charge cycle. In simple terms, it is the process of the lithium battery from full to empty and then from empty to full. Nowadays, the lifespan of lithium batteries is generally 300-500 cycles, so if the battery is used normally, it can be used for a long time.
2. Do not repeat 90% to 100%, or overload. So-called overcharging means that you cannot wait to fully charge the battery after using only a few percent of the battery. in this range, the battery will be seriously damaged, especially the 90% to 100% battery range. In this case, don't charge blindly. After using it for a while, remove the power source and use the battery as a battery.Lifespan When the battery is consumed below 80%, recharge it again.
3. Do not over-discharge, for example, always use the battery until less than 5% remains. This actually has nothing to do with the lithium battery itself, but is mainly caused by the battery. laptop power management chip. If the battery is too low, the voltage will naturally drop. At this time, the battery management chip may think there is a battery problem and then lock the battery. Therefore, it is best to keep it. battery power is more than 20%.
4. Lithium batteries are afraid of heat and collision. Make sure the laptop is used in a comfortable environment, i.e. the ambient temperature is neither too high nor too low. only damage the battery, but also damage the battery. The computerTheir laptop itself does not provide any service. Of course, avoid direct sunlight.
5. When using a laptop, try to connect it to the power source, do not use battery power, and choose to remove the battery when it is not the battery. Today's laptops basically have batteries that can be removed and installed freely. You should choose to remove the battery and store it separately when the battery is at a higher level.
Detailed information:
The number of charging and discharging times of the batteries at lithium is generally the same. does not exceed 800 times. Each time it is recharged, its lifespan is shortened. It is recommended to use an external power supply whenever possible. If the power supply needs to be plugged and unplugged several times during use and thethe built-in battery of the laptop is not removed, the battery life will be greatly reduced. , because each time the external power supply is connected, it is equivalent to charging the battery once.
Zhongguancun Online-Double.11 Shopping Tips Do you really know the battery capacity?
Laptop batteries are roughly divided into two types , one is the most commonly used lithium battery. Batteries and nickel-metal hydride batteries each have their own advantages and disadvantages. Ni-MH batteries have a high single-cell capacity, but their voltage is low, so the size of nickel-metal hydride batteries is a bit large, so laptops using nickel-metal hydride batteries are not very small. Lithium batteries are more practical. There are 18650 and 103448 (thin) lithium batteries in laptop computerstables. very light and has a large capacity.
