It can be used as a hand luggage to carry portable electronic devices and backup batteries for laptops, mobile phones, cameras, watches, etc., containing no more than 100Wh (lithowatt hours) of lithium batteries.
1, it is determined if the lithium battery rated capacity of the lithium battery is not marked directly nominal energy Wh (watt-hours), the lithium battery may be rated in terms of energy as follows:
1) If the nominal voltage (V) and nominal capacity (Ah) of the battery are known, the value of the nominal watt hour can be calculated by calculation: Wh = VxAh, the nominal voltage and nominal capacity are usually marked on the battery.
2) If the battery is only marked with milliampere (mAh), divide this value by 1000 to get ampere-hours (Ah).
For example, the nominal voltage of a lithium battery is 3.7V, the nominal capacity is 760mAh, and its rated watt hours are: 760mAh/1000=0.76Ah; 3.7Vx0.76Ah=2.9Wh
2. Protection measures for spare lithium batteries The backup batteries must be individually protected against short circuits (insert the original retail packaging or otherwise insulate the electrodes, such as tape on exposed electrodes or separate each battery into a separate one) Among plastic bags or protective boxes).
3, portable lithium battery can be used for carrying luggage with no more than 100Wh (watt hours) lithium battery notebook computers, mobile phones, cameras, watches and other personal use portable electronic devices and backup batteries boarding.
Generally speaking, the rated energy of the lithium battery of the mobile phone is 3~10Wh; the energy of the lithium battery of the SLR camera is 10~20Wh; the energy of the lithium battery of the portable camera is 20-40Wh; the energy of the lithium battery of the notebook computer is 30-100Wh More than a little. Therefore, lithium batteries in mobile phones, commonly used camcorders, SLR cameras, and most electronic devices such as laptops usually do not exceed the 100Wh limit.
