Which threshold defines UN 3480 Lithium Ion Batteries for cells and batteries?

• A. Cells greater than 20 Wh and Batteries greater than 100 Wh
• B. Cells greater than 200 Wh and Batteries greater than 1000 Wh
• C. Cells greater than 5 Wh and Batteries greater than 25 Wh
• D. Cells greater than 1 Wh and Batteries greater than 2 Wh

Answer: (A)

The key idea is that UN 3480 defines different transport rules based on capacity, measured in watt-hours. For lithium ion cells, the threshold is 20 Wh per cell. For lithium ion batteries, the threshold is 100 Wh per battery. Exceeding these amounts means stricter packaging, labeling, and documentation requirements as larger batteries require more oversight during transport. Among the options, the correct thresholds are 20 Wh for cells and 100 Wh for batteries, which is why that choice is right. The other thresholds don’t match the standard UN 3480 limits and would imply different, incorrect regulatory requirements.
