Which description best matches UN 3481?

• A. Lithium ion cells or batteries contained in or packed with equipment
• B. Lithium ion batteries shipped without equipment
• C. Lithium metal batteries in equipment
• D. Non-rechargeable batteries packed with gear

Answer: (A)

UN 3481 describes lithium ion batteries that are contained in equipment or packed with equipment. This means the batteries are part of the device during transport or shipped alongside the device, rather than being sent separately. The other scenarios refer to different classifications: standalone lithium ion batteries not in equipment fall under a different UN number; lithium metal batteries have their own separate numbers; and non-rechargeable batteries packed with gear involve a different category altogether. So the best match is lithium ion cells or batteries contained in or packed with equipment.
