How to pack and ship wet batteries
A wet cell battery is the original type of rechargeable battery, and thus has a longer shelf life than dry cell batteries. Wet cell batteries get their power from a liquid electrolyte and generate gases, meaning they must be vented and kept upright during transportation to avoid leakage.
Like lithium batteries, there are strict regulations to follow when shipping wet batteries internationally.
An IATA Dangerous Goods label must be attached, along with the correct UN number and shipping name for the particular type of batteries.You must also complete a Dangerous Goods Shipper's Declaration, detailing the contents and potential hazards of the shipment.
For example, in Morocco an industrial supplier in Tangier exporting wet lead-acid batteries for forklifts to factories in Spain must ship them upright with leak-proof vented packaging, IATA Dangerous Goods labels, the correct UN number, and a shipper’s declaration to comply with cross-border safety regulations.
