The ability to carry personal portable electronic devices such as laptops, cell phones, cameras, watches and spare batteries on board, with no more than 100 watt-hours of lithium-ion batteries in your carry-on.
Part one :Measurement Methods
Determination of additional energy of lithium-ion battery If the additional energy Wh (watt-hour) is not directly labeled on the lithium-ion battery, the additional energy of lithium-ion battery can be converted by the following methods:
(1) If the rated voltage (V) and rated capacity (Ah) of the battery are known, the value of the additional watt-hour can be calculated: Wh = VxAh. Nominal voltage and nominal capacity are usually labeled on the battery.
(2) If the only symbol on the battery is mAh, divide by 1000 to get Ampere hours (Ah).
Such as lithium-ion battery nominal voltage of 3.7V, nominal capacity of 760mAh, the additional watt-hour is: 760mAh/1000 = 0.76Ah; 3.7Vx0.76Ah = 2.9Wh
Part two :Alternate maintenance measures
Lithium-ion batteries are necessary to be maintained individually to prevent short-circuiting (place in original retail packaging or insulate electrodes in other areas, such as adhesive tape contacting the electrodes, or place each battery in a separate plastic bag or next to a maintenance frame).
Working summary:
Typically, the extra energy of a cell phone's lithium-ion battery is 3 to 10 Wh. The lithium-ion battery in a DSLR camera has 10 to 20 WH. Li-ion batteries in camcorders are 20 to 40 Wh. Li-ion batteries in laptops have a range of 30 to 100 Wh of battery life. As a result, lithium-ion batteries in electronic devices such as cell phones, portable camcorders, single-lens reflex cameras, and most laptop computers typically do not exceed an upper limit of 100 watt-hours.
