Lithium batteries are widely used in people's lives, such as digital products such as cameras and notebook computers, as well as some other electrical appliances.

safe transportation of lithium batteries

Tips for safe transportation of lithium batteries:

1. Allowed portable lithium battery: It can be used as hand luggage to carry personal portable electronic equipment such as notebook computers, mobile phones, cameras and other spare batteries containing no more than 100Wh lithium batteries and spare batteries to board passenger aircraft.

2. Restricted lithium batteries: With the approval of airlines, electronic equipment that can carry more than (including) 100Wh but not more than 160Wh lithium batteries can be boarded. Each passenger cannot carry more than two such spare lithium batteries and cannot consignment.

3. Prohibited lithium batteries

It is forbidden to carry or consigne large lithium batteries or electronic equipment over 160Wh (except wheelchairs with lithium ion batteries).

4. Protection measures for lithium batteries

Spare batteries must be individually protected against short circuits (put in original retail packaging or otherwise insulate the electrodes, such as sticking tape on the exposed electrodes, or placing each battery in a separate plastic bag or protective box)

5. Lithium batteries that are not labeled with lithium content cannot be brought on board

Lithium batteries with lithium content exceeding the standard or not marked with lithium content will be refused transportation at the airport. The refusal to transport is as follows:
    1). Lithium battery with lithium content or rated energy> 2g or> 160wh;
    2). Lithium batteries that do not indicate the lithium content or rated energy;
   3). Lithium batteries that are confirmed as defective or damaged by the manufacturer for safety reasons.

Calculation method of battery lithium content or rated energy:

1. Calculation method of rated energy:

A. If the nominal voltage (V) and nominal capacity (Ah) of the battery are known, the value of the rated energy can be obtained by calculation:

Wh = V x Ah

Nominal voltage and nominal capacity are usually marked on the battery.

B. If only the milliampere hour (mAh) is marked on the battery, divide this value by 1000 to get the ampere hour (Ah).

For example: the nominal voltage of the battery is 3.7V, the nominal capacity is 760 mAh, and its rated energy is:

760 mAh ÷ 1000 = 0.76Ah

3.7V × 0.76Ah = 2.9Wh

2. Calculation method of lithium content in lithium battery:

If the battery is marked with current (mAh), you can divide the data by 1000 and multiply by 0.3 to get the grams of lithium content of the battery.

For example, if the battery current is 4600mAh, the lithium content is 4600mAh ÷ 1000 X 0.3 = 1.38 grams, which is less than 2 grams, which meets the safety standards.
