How can a shipper verify that the battery's Wh rating is correct?

• A. By checking the battery's documentation or label and using supplier data.
• B. By guessing based on battery size.
• C. By using the device manual.
• D. By assuming a standard 10 Wh.

Answer: (A)

Verifying the exact watt-hours comes from using the official energy value published by the manufacturer or supplier. The watt-hour rating is the documented energy content of the battery, and shipping rules rely on that precise figure to determine classifications and packaging. The most reliable way to confirm it is to check the battery’s label and the supplier’s documentation or data sheet, which specify the watt-hours or provide the exact values needed for verification. This avoids guessing based on physical size or relying on a device manual, which may describe usage but not certify the battery’s exact energy content. If the label or docs don’t show the watt-hours, you can calculate it from voltage and capacity (in ampere-hours) provided by credible sources, but the verified value should come from the manufacturer or supplier data.
