La Belle Batterie - Unlocking the second-hand electrical market by offering accurate, independent and transparent information on the state of electric vehicles battery

La Belle Batterie is the first certification service for EV and PHEV batteries. Its mission is to unlock the second-hand electrical market by offering consumers and professionals accurate, independent and transparent information on the state of health of electric vehicles (EV) and plug-in hybrid vehicles batteries (PHEV)

The "La Belle Batterie" certificate enables buyers of used electric vehicles to have more information about the vehicle they want to buy. Therefore, sellers will also be able to sell faster and with transparency, which could result in an increase. With La Belle Batterie, customers can diagnose their vehicle themselves, in 5 minutes, directly at home. No more need for expensive labour in a garage. This solution is also available for car aftermarket professionals, such as garages or used car dealers.
