Battery Shipping: Classification, Best Practices, and more | Maersk
Lithium batteries need to be shipped with care to avoid issues like delays or rejected cargo. Due to their potential fire risk, they are considered dangerous goods and must follow
Only a maximum of four can be sent, with two per container, and each battery must have a rating of below 100 watts per hour. It is essential to note that some countries have their own regulations and restrictions for shipping lithium batteries, so it is crucial to check with the destination country's customs authorities before shipping.
Improperly packaged lithium batteries can ignite, causing fires that are difficult to extinguish and pose a significant risk to the safety of transportation workers and the general public. Other battery types, such as alkaline or nickel-metal hydride (NiMH), are generally considered safer to ship.
In addition, a Shipper's Dangerous Goods Declaration (DGD) is generally required when shipping fully regulated lithium batteries, such as those not meeting exemption criteria. However, the need for a DGD depends on factors like battery type, quantity, and mode of transport – with air and ocean regulations differing significantly.
When you're shipping lithium-ion batteries by air, it's essential to follow specific regulations regarding their state of charge (SoC). The SoC, which reflects the battery's charge level compared to its full capacity, must not exceed 30% during transit.
