Specialty battery systems

From automated guided vehicles (AGV) to military applications, we design and manufacture specialised, custom-made, low-voltage battery systems for a wide range of demanding applications. Our battery systems are integrated with control electronics. Customised housings, as well as the charging equipment, are designed on a case-by-case basis to ensure the best possible fit for each application.


The power tool sector, especially the professional segment, requires batteries with extreme robustness, maximum power and energy density. The capability to combine balanced technology to meet cost and performance is key. The voltage range usually exceeds legacy battery pack solutions and requires strict competencies.


In medical applications, the engineering and official certification requirements are so demanding that choosing the right partner is crucial. Reliability and solution efficiency make a huge difference. The power supply cannot fail; it must work. To achieve this goal, battery experience alone is not sufficient. It requires global expertise in battery, hardware and regulations.

Military and Defence Applications

In this very exacting sector, equipment is exposed to the harshest environmental conditions whether in simulation training or real battle conditions. Reliability means keeping soldiers alive and giving them tactical advantages. Executing military projects requires unique know-how which Leclanché has acquired over the past 20 years.

Robotics & AGV

Robots used in production processes are essential to ensuring quality and efficiency controls. Our engineered battery solutions, which integrate fast charge technologies and high levels of intelligence, enhance robots’ capabilities. We not only provide battery and related controls but a complete turnkey solution, which includes charger, docking station and a remote access platform. AGVs are a typical application where our fast-charging technology dramatically reduces downtime.

Portable Systems

We design and manufacture portable systems for the most demanding situations. We meet the challenges of extreme conditions to ensure our batteries and systems reliably continue to perform when you need them. Typical customers include integrators of defence and simulation equipment.
