At Fuji EnviroMAX, they are dedicated to setting environmental standards with the batteries they make. At one time, all batteries were made with mercury and cadmium, which are heavy metals. These heavy metals, along with other materials, have been proven to be harmful to the environment. Fuji Batteries decided they wanted to confront this environmental danger head-on, so they developed Fuji EnviroMAX to eliminate the use of materials like mercury and cadmium, which were hazardous to the environment.
