Find a single checklist

Damaged/Defective according to the Dangerous Goods Transport Regulations is when at least one of the following criteria is fulfilled for the cells / batteries:

• Cells / Batteries were identified as being defective for safety reasons.
• Cells / Batteries have leaked or vented.
• Cells / Batteries have sustained physical or mechanical damage.
• Cells / Batteries cannot be diagnosed prior to transport.

Note:
In assessing a cell or battery as damaged or defective, an assessment or evaluation shall be performed based on safety criteria from the cell, battery or product manufacturer or by a technical expert with knowledge of the cell’s or battery’s safety features. An assessment or evaluation may include, but is not limited to, the following criteria:

1. Acute hazard, such as gas, fire, or electrolyte leaking;
2. The use or misuse of the cell or battery;
3. Signs of physical damage, such as deformation to cell or battery casing, or colours on the casing;
4. External and internal short circuit protection, such as voltage or isolation measures;
5. The condition of the cell or battery safety features; or
6. Damage to any internal safety components, such as the battery management system.

If the assessment of a qualified person ensures that the cells/batteries under normal transport conditions NOT prone to rapid disintegration, dangerous reaction, flame formation, dangerous heat development then select the checklist for "defective/damaged" (5-5).

If the assessment of a qualified person has ensured that the cells/batteries are prone to rapid decomposition, dangerous reaction, flame formation, dangerous heat development under normal transport conditions, then select the checklist for "safety-critical defective" (5-6).

1. The Watt-hour Rating is calculated using the nominal voltage in Volt (V) and the capacity Ampère hours (Ah) in the following formula:

   Wh = V x Ah

   Take for example the accumulator of a mobile phone: 3,7 V x 1500 mhA = 3,7 V x 1,5 Ah = 5,55 Wh
   Newer lithium ion batteries show the Wh amount on the outer casing of the battery.

   You might need to contact the battery manufacturer or use the material data sheet in order to determine the Wh amount.

2. What is the difference between a cell and a battery? (see Frequently Asked Questions)

1. You might need to contact the cell / battery manufacturer or from the UN 38.3 Test Summary in order to determine the amount of grams.

Total lithium content means the sum of all lithium metal content of the lithium metal cells contained in the lithium hybrid battery.

Total nominal energy means the sum of all nominal energies of the lithium ion cells contained in the lithium hybrid battery.
