Why are lithium batteries restricted for air shipping and what are the limits?

Short answer Lithium batteries are restricted for air shipping due to their potential fire hazard. When transported improperly, they can overheat, catch fire, or even explode. The limits for shipping lithium batteries vary based on their watt-hour (Wh) rating and whether they are contained within devices or shipped separately. What to check Battery type: Ensure you know whether the battery is lithium-ion or lithium metal. Watt-hour rating: Check the watt-hour rating for lithium-ion batteries (typically limited to 100 Wh for air transport). Weight: Confirm the weight of the battery, as there are restrictions on the total weight allowed for air shipping. Packaging: Ensure that the battery is packaged according to the carrier's guidelines, including proper labeling. Carrier policies: Review the specific policies of your chosen carrier regarding lithium battery shipments. What to do next Identify the type of lithium battery you are shipping and its specifications. Check the watt-hour rating if it is a lithium-ion battery, ensuring it does not exceed the limits set by your carrier. Contact the seller or manufacturer for any specific shipping guidelines related to the battery. Review your carrier's shipping policies to confirm they allow the shipment of lithium batteries. Package the battery securely, following all regulations and guidelines for hazardous materials. Label the package correctly, indicating that it contains lithium batteries. Arrange for pickup or drop-off with your chosen carrier, ensuring you comply with any additional requirements. Common pitfalls Not checking the watt-hour rating, leading to potential rejection of the shipment. Improper packaging that does not meet safety regulations.
