Section I states thresholds: Cells greater than what watt-hours and Batteries greater than what watt-hours?

Section I states thresholds: Cells greater than what watt-hours and Batteries greater than what watt-hours?

• A. Cells greater than 10Wh and Batteries greater than 50Wh
• B. Cells greater than 20Wh and Batteries greater than 100Wh
• C. Cells greater than 50Wh and Batteries greater than 200Wh
• D. Cells greater than 100Wh and Batteries greater than 500Wh

Answer: (B)

The main idea is that energy content in lithium-ion cells and batteries determines when extra air-shipping rules apply. The thresholds act as cutoffs: once a cell has more than 20 watt-hours, it falls under more stringent packaging and handling rules; once a battery has more than 100 watt-hours, it triggers even tighter requirements. This pairing—cells over 20 Wh and batteries over 100 Wh—is what Section I uses, so it’s the correct match. Think of it in practical terms: small items like many smartphone batteries (well under 20 Wh) stay under lighter rules, while larger batteries (over 100 Wh) require UN packaging, special labeling, and possibly additional approvals. The other threshold sets don’t reflect the policy in Section I, so they don’t represent the point at which these enhanced requirements begin.
