The first battery with a lifetime capacity guarantee
We manufacture and market second-life batteries for small and medium-scale photovoltaic storage. Thanks to their reparability, our batteries are the most affordable and sustainable on the market. Our subscription model guarantees our customers long-term battery capacity.
Your energy, your battery, our guarantee
Our second-life batteries come with a capacity guarantee, so that our customers can enjoy their energy with complete peace of mind over the long term.

1 - Collecting
We recover lithium-based batteries after their first life in micro-mobility from our partners, Decathlon Switzerland in particular, to avoid their premature destruction in the conventional recycling scheme.

2 - Test
After dismantling the batteries down to the single cell, we test each cell on our robotized installation. Almost 80% of the cells tested can be reused in our second-life batteries.

3 - Reconditioning
Our battery architecture, entirely developed by our teams, guarantees optimum use of each cell and long-term battery reparability.
