Electronic devices

We reduce the impact of the batteries in your electronic devices

From the standard model compatible with major brands to the tailor-made model, we address all types of devices for industrial or domestic use (portable electrical, lighting, home automation, handling equipment, etc.)

A solution for every need


We give a second life to your out-of-use batteries thanks to our reconditioning activity.

Make it last

We are in a position to establish an accurate diagnosis of the health status of your batteries thanks to our characterization technology.


No need to import your batteries or cells from China, our batteries are manufactured in France in our factory located in Angers.


We manufacture batteries from second-life cells while guaranteeing a level of performance greater than or equal to new.
