Environmental Compliance: Environmental compliance refers to adherence to standards that protect users from hazardous materials in batteries. Many batteries contain substances that can be harmful if managed improperly. Standards such as RoHS (Restriction of Hazardous Substances) ensure that the materials used in batteries are non-toxic and that products are recyclable. Compliance can also lead to reduced environmental impact over the product’s life cycle, aligning with increasing global sustainability goals.
