Import Tips
• Zinc-air cells ship with protective tabs; damaged seals cause premature activation and duty disputes
• Lower voltage (1.4V) distinguishes from alkaline LR44 equivalents for proper HTS selection
• Hearing aid zinc-air batteries often get medical duty treatment - verify end-use certificates
