Transporting data loggers with lithium batteries

Most of Gemini’s Data Loggers are powered by lithium batteries (‘lithium metal cells’) which have regulations restricting their transportation by road, sea or air due to the hazardous nature of lithium.

Many Tinytag data loggers are powered by lithium batteries ('lithium metal cells') which are subject to regulations restricting their transportation.

Provided there are no more than four data loggers contained per package (each logger containing one lithium metal cell) then the package may be transported freely anywhere in the world by ground or air. Please note however:

  • This only applies to data loggers with batteries fitted (not spare batteries or service kits)
  • The data loggers and the batteries in them must be free from damage.
  • All batteries inside the data loggers must meet the requirements in the UN Manual of Tests and Criteria, Part III, Subsection 38.3 and must contain less than 1g of lithium.

All batteries supplied by Gemini Data Loggers meet these requirements. Customers are responsible for checking the compliance of any batteries not supplied by Gemini Data Loggers.

Please note that many replacement lithium 'c' cells (the battery used by some Tinytag Radio loggers) contain more than 1g of lithium. For this reason when returning any lithium battery powered Radio loggers to us they must be sent without their batteries.

Shipments containing more than four loggers

When transporting more than four loggers (each containing one lithium metal cell) by ground or air the following additional shipping instructions must be adhered to*.

  • Pack loggers in strong, rigid outer packaging to protect them from damage (e.g. a ridged cardboard box).
  • Attach a Lithium Mark to the package. Please note, this label must be printed in black and red as shown in the link. The minimum size is 120 x 110mm, and the telephone number of someone knowledgeable about the shipment must be added.

* Shipping instructions given here are general guidelines. Some carriers may have additional requirements (e.g. declaring the hazard on the Consignment Note as partially regulated lithium metal batteries in equipment UN3091/P.I. 970 Section II). Customers are responsible for checking their local regulations and any carrier specific requirements.
