Avoid Delays & Fines: Ultimate Guide to Safely Shipping Lithium Batteries Internationally (100Wh)
1Ah = 1000mAh
Voltage (V) × Capacity (Ah) = Watt-hour (Wh)
Voltage (V) × Capacity (mAh) / 1000 = Watt-hour (Wh)
✅ Example:
3.7V × 2600mAh ÷ 1000 = 9.62Wh
📦 Inner Packaging Requirements
Each battery must be properly labeled and individually protected to prevent short circuits and physical damage.
Each battery must show Voltage (V), Capacity (mAh), and Model Number
All wire ends must be fully insulated
Individual Packaging: One battery per bag, then placed in an inner box
Tray Packaging: Each cell must be separated and fixed to prevent movement
Slot Packaging: One battery per slot, no movement allowed
With wires: Each wire end must be insulated with non-conductive material
Fill Empty Space: Ensure boxes are fully filled to prevent shaking during transport
🔋 Packaging for Batteries Below 99Wh
Minimum outer carton weight: 2.5 kg (suitable for labeling and safe handling)
Required labels: Cargo aircraft only label, Class 9 label, caution label, address label
Carton quality: Must be strong, clean, and new; avoid yellow sealing tape or damaged boxes
Weight limit per carton: ≤ 10 kg (ideal 9.8 kg + 0.2 kg for documents)
Fill completely: No empty space; carton should not collapse under pressure
Recommended carton dimensions:
Square box: 30 × 16 × 25 cm
Rectangular box: 48 × 24 × 17 cm
⚙️ Packaging for Batteries Above 100Wh
Must use UN-certified cartons (default SGP model recommended)
Minimum carton weight: 4.5 kg
Labels: Cargo aircraft only, Class 9, and address label (three sides)
Weight control: Should not exceed the UN-rated limit; ideal per carton ≤ 23.8 kg + 0.2 kg for documents
Fill completely: Ensure the carton is firm and not deformable under pressure
All boxes in the same shipment should use the same UN model code
Note: Using non-standard box types (e.g. CNY model) is at the shipper’s own risk
