Under Section II, what are the watt-hour limits for cells and batteries?

• A. Cells equal to or less than 20Wh; Batteries equal to or less than 100Wh
• B. Cells equal to or less than 50Wh; Batteries equal to or less than 150Wh
• C. Cells equal to or less than 10Wh; Batteries equal to or less than 50Wh
• D. No limits

Answer: (A)

The main idea is that there are safety limits on how much energy a lithium battery or its individual cells can store when shipped, to reduce the risk of fire during transport. Under Section II, the allowed energy capacities are set so that individual cells may be up to 20 watt-hours, and complete batteries (packs) may be up to 100 watt-hours. This distinction matters because a single cell has less total energy than a full battery packed with multiple cells, so the higher limit applies to the assembled battery. If a cell or battery exceeds these thresholds, it falls under more restrictive shipping rules and may require different packaging, labeling, or even hazardous materials treatment. The other options propose different limits or claim no limits, which do not align with these safety thresholds.
