Battery certification is not just a legal checkbox — it’s the key to ensuring safety, reliability, and global market access. From electric bikes and scooters to energy storage systems and EVs, compliance with certification standards determines whether your product can be sold, shipped, and safely used worldwide.
Battery certification covers safety, performance, transportation, and environmental standards such as UL, EN, UN 38.3, CE, FCC, IEC, IP67, ECE R136, etc. These certifications verify that a battery meets strict regulations for global market entry, ensuring it is safe, reliable, and compliant in different regions.
If you’re a manufacturer, importer, or product designer, navigating battery certifications can be daunting. In this guide, we’ll break down the most important battery certifications, explain their testing requirements, and show how they differ across markets — so you can confidently launch your product worldwide while ensuring battery compliance with international regulations..
Why Battery Certification Matters
