International transportation of lithium batteries, whether by sea or air, requires a UN38.3 report and MSDS.
1.UN38.3 is the testing standard. The full name can be found in Section 38.3 of Part 3 of the “Manual of Testing and Standards for the Transport of Dangerous Goods” specially formulated for the transport of dangerous goods, which requires lithium batteries to pass successfully a high level, high and low level simulation. Temperature cycles and vibrations before transport. Testing, impact testing, external short circuit at 55°C, impact testing, overload testing and forced discharge testing can ensure the transportation safety of lithium battery. If the lithium battery is not installed with the device and each package contains more than 24 cells or 12 batteries, it must also pass the free fall test1.2 meters.
2.MSDS (Material Safety Data Sheet) is the chemical safety data sheet. It is used by chemical manufacturers and importers to clarify the physical and chemical properties of chemicals (such as pH value, flash point, flammability, reactivity, etc.) and possible effects on the health of users (such as induction, teratogenic, etc.) A document of the dangers generated.
I hope the above is helpful to you. If the answer is helpful to you or other passing friends, please accept and like it. Thank you very much~
First of all, lithium batteries are usually equipped with a protective plate to prevent overloading and overloading. -discharge problems. If it is determinedIf the battery is too discharged, the protection panel will also protect it. It is recommended to do the following (operate with caution): 1. Disassemble the battery and separate the battery and the protection board. 2. Apply a voltage of 5 V. To the positive and negative terminals of the battery. Pay attention to using low current and duration. 3. Install the protection panel, 4. Charge or use the test.
Principle. : Directly adding a voltage higher than that of the battery is a forced charging process for the battery. Because the plate guard is ignored, the battery will be charged, allowing the plate guard to continue to operate.
