Leclanche battery


Leclanché made an early investment in developing a DNV-GL certified battery system for marine applications, and is the first battery supplier to fully comply with the stringent 2015 regulations that are currently in force.

As international marine regulations continue to limit SOx and NOx emissions, our energy storage systems provide all electric and hybrid power solutions that bring game-changing efficiencies and reduce the environmental impact of all vessel types. Customer applications include ferries, tugboats and container ships.

Leclanché is working on a project in Denmark to create the world’s largest fully electric ferry, connecting the island of Aero to Als in southern Denmark. The landmark project, backed by the EU, will replace diesel-powered ferries, creating energy saving of up to 50% and major emission reductions. Read more here.


The system has been designed to provide the safest practical operation on board a vessel:

  • Fire suppression architecture
  • Leclanché G-NMC cell technologies
