Battery certification is far more than a legal checkbox—it’s the key to global market access, product safety, and customer trust. For businesses selling lithium batteries powering e-bikes, energy storage systems, EVs, or consumer electronics, complying with international standards determines whether your products can be sold, shipped, and used safely worldwide. In this guide, we break down the most critical battery certifications, their requirements, and regional differences to help you navigate global compliance with confidence.
Why Battery Certification Matters
- Safety Assurance: Prevents fires, explosions, and electrical hazards during use, charging, and transport.
- Market Access: Mandatory for importing or selling batteries in most countries (e.g., UL for North America, CE for the EU).
- Risk Mitigation: Reduces legal liabilities and warranty claims by proving compliance with global regulations.
- Customer Trust: Certified products are more attractive to buyers and OEM partners, signaling reliability.
Key Global Battery Certifications: Details & Requirements
1. UL (Underwriters Laboratories) – U.S. & Global Safety Standard
UL is a leading independent safety certification body based in the U.S., renowned for rigorous testing of electrical products. It’s a prerequisite for entering the North American market and widely recognized worldwide.
- Core Purpose: Ensure battery safety under normal and fault conditions (e.g., short circuits, overcharging).
-
Key Standards:
- UL 1642: Lithium battery cells (cell-level safety tests).

- Cost & Timeline: $150,000 – $200,000; 10 – 12 weeks (requires testing 52 battery packs).
- Region: U.S. (globally recognized); annual factory inspections required to maintain certification.
2. EN Standards – EU Safety & Performance
EN (European Norms) are adopted by the European Committee for Standardization (CEN), aligned with IEC standards. They form the basis for CE marking, mandatory for EU market access.
- Core Purpose: Comply with EU safety, EMC (Electromagnetic Compatibility), and environmental directives.
-
Key Standards:
- EN 15194: Electrically Assisted Pedal Cycles (EPACs/e-bikes).

3. UN 38.3 – Global Transport Safety
UN 38.3 (UN/DOT 38.3) is a mandatory certification for shipping lithium batteries via air, sea, road, or rail. All lithium-ion/lithium-metal batteries are classified as "dangerous goods" and require this certification for global transport.
- Core Purpose: Ensure safe handling and transport to prevent accidents.
- Key Tests: Altitude simulation, thermal testing, vibration, impact, short circuit, overcharging, forced discharge.
- Cost & Timeline: $40,000 – $70,000; 4 – 6 weeks (tests 16 battery packs).
- Region: Global; self-declarable but often verified by third-party labs (e.g., Intertek, TÜV SÜD).
4. CE Marking – EU Market Access
CE (Conformité Européenne) is a self-declaration mark indicating compliance with EU directives. For batteries, it requires adherence to safety, EMC, and environmental standards.
- Core Purpose: Declare compliance with EU directives for legal sale in the EU/EEA.
-
Applicable Directives:
- EMC Directive (2014/30/EU): Electromagnetic compatibility.
- Low Voltage Directive (2014/35/EU): Electrical safety.
- RoHS Directive (2011/65/EU): Restriction of hazardous substances.
- Cost & Timeline: $50,000 – $100,000; 4 – 6 weeks (documentation and testing required).
- Region: EU and EEA; self-declared but requires retained test records.
5. FCC (Federal Communications Commission) – U.S. EMC & Wireless Compliance
The FCC regulates electromagnetic interference (EMI) in the U.S. Batteries with wireless components (e.g., Bluetooth, 4G) need FCC certification to avoid interfering with other electronic devices.
- Core Purpose: Ensure wireless/battery systems don’t cause radio frequency interference.
-
Key Parts:
- Part 15B: Unintentional radiators (EMC).
- Part 15C: Intentional radiators (Bluetooth, Wi-Fi).
- Parts 22/24/27: Cellular modules (2G/3G/4G).
- Cost & Timeline: $40,000 – $70,000; 3 – 5 weeks.
- Region: U.S. (accepted in some other markets).
6. IEC (International Electrotechnical Commission) – Global Standards
IEC develops international electrical standards that form the basis for national certifications worldwide. IEC certification (via the CB Scheme) facilitates global trade by recognizing tests across countries.
- Core Purpose: Ensure global safety and performance consistency.
-
Key Standards:
- IEC 62133-1/2: Portable sealed secondary batteries.
- IEC 62660-1/2: EV lithium-ion battery performance and safety.
- IEC 62619: Industrial battery safety.
- IEC 61427: Batteries for renewable energy storage.
- Cost & Timeline: $70,000 – $100,000; 6 – 8 weeks (tests 33 sealed packs + 11 open packs).
- Region: Global; integrated into local standards.
7. IP Rating – Global Dust & Water Protection
IP (Ingress Protection) ratings verify a battery’s resistance to dust and water, critical for outdoor applications (e.g., e-bikes, solar storage).
- Core Purpose: Ensure safe use in harsh outdoor environments.
- Example: IP67 = "6" (full dust protection) + "7" (protection against immersion in 1m of water for 30 minutes).
- Cost & Timeline: $10,000 – $20,000; 1 – 2 weeks.
