We will analyze the **Certification of Lead Acid [Batteries](https://cnbatteries.com/products/)**, differences in **production standards**, methods for determining compliance, and real-world examples, deeply exploring user concerns and providing solutions. ## **1. Qualification Certification System: Requirements in Major Global Markets** ### **China** **Mandatory Certification:** - **GB 44240-2024**: China’s first mandatory national standard for lithium battery safety in energy storage applications (also applicable to [lead-acid](https://cnbatteries.com/products/) battery storage scenarios). It covers cell vibration, needle penetration, and forced discharge tests, taking effect on August 1, 2025. **Voluntary Certification:** - **CQC Certification**: Issued by the China Quality Certification Center, covering standards like **GB/T 19638** (for stationary valve-regulated lead-acid batteries) and **GB/T 5008** (for starter lead-acid batteries). **Green Product Evaluation:** - **GB/T 42391-2023 (“Green Product Evaluation Specifications – Lead-Acid Batteries”)**: Focuses on environmental indicators and full lifecycle pollution control to promote green industry transformation. ### **International Certifications** ##### **IEC Standards:** - **IEC 60896** (stationary valve-regulated batteries) - **IEC 60095** (starter batteries) These are internationally recognized standards covering performance and safety testing. ##### **United States:** - **UL 1989** (backup battery safety standard) - **UL 1778** (UPS system standard) These focus on explosion prevention and thermal runaway protection. ##### **Europe:** - **EN 61056** (general battery pack specifications) - **EN 60254** (traction battery standards) Compliance with **CE certification** is required, emphasizing environmental protection and recycling. ##### **Japan and South Korea:** - **JIS C 8702** (Japanese Industrial Standard) - **KC 62619** (Korean energy storage battery safety certification) These require high-temperature stability and long cycle life. ##### **Other Regions:** - **India**: **BIS certification (IS 1651 standard)**, ensuring battery capacity and high-temperature endurance. - **Southeast Asia**: Mostly follows **IEC standards**, with some local adaptations (e.g., Thailand’s **TISI certification**). ## **2. Manufacturer Qualification Requirements and Compliance Verification** ### **Core Certifications:** - **Quality Management System:****ISO 9001** is the basic requirement; some manufacturers need **IATF 16949** (automotive industry standard). - **Environmental Permits:** Compliance with **China’s “Lead-Acid Battery Industry Access Conditions”** or **EPA (U.S. Environmental Protection Agency) pollution control requirements**. - **Product Certification:** CQC (China), UL (U.S.), CE (Europe), issued by recognized institutions like **Beijing Jianheng Certification Center, TÜV Rheinland**, etc. ### **How to Verify Compliance** - **Certification Authority Authenticity:** For example, **UL certification** must be tested by **Underwriters Laboratories**, and **CE certification** must be approved by an **EU Notified Body**. - **Public Verification Platforms:** In China, the **National Standard Information Public Service Platform** allows verification of GB standard compliance. - **Supply Chain Transparency:** Reputable companies disclose material suppliers (e.g., electrolyte meeting **GB/T 42391-2023 standards**). ## **3. Production Standard Differences and Product Performance** ### **China’s GB Standards:** - **GB/T 19638**: For **stationary valve-regulated batteries**, focusing on cycle life (≥350 cycles) and explosion protection. - **GB/T 5008**: For **starter batteries**, emphasizing **cold start performance (current output at -18°C)**. ### **International Comparisons:** - **IEC 60896 vs. UL 1989**: IEC focuses on **long-term float charge life**, while UL prioritizes **short-circuit protection and thermal runaway testing**. - **EN 61056 vs. JIS C 8702**: European standards emphasize **recycling and environmental protection**, while Japan’s standard strictly limits **electrolyte leakage risks**. ### **Impact of Standards on Product Performance:** - **High-Temperature Adaptability:****IEC 60254-compliant traction batteries** operate stably at **55°C**, suitable for **tropical regions**. - **Energy Density:** U.S. **UL-certified batteries** optimize **space utilization (e.g., AGM technology)**, while China’s **GB standards** prioritize **safety**. ## **4. Case Studies and Market Trends** - **Envision Energy**: Expected to receive **China’s first GB 44240 certification** in 2025. Their **energy storage batteries** pass **200+ global tests** across **UL, IEC, KC**, and other standards, ranking among the top three in global shipments. - **Leoch International**: **China’s largest lead-acid battery exporter**, strengthening its presence in the U.S. and Europe via **Leoch Energy**. Their products meet **UL 1989 and EN 61056** standards. - **China Mobile Procurement**: In the **2025 tender**, they require **lead-acid batteries** to meet **GB/T 19638 and IEC 60896** standards. High-power models must pass **≥350-cycle lifespan tests**. ## **5. Risks of Incomplete or Non-Compliant Certifications** If a **lead-acid battery manufacturer** lacks the necessary **product and production certifications**, potential consequences include: 1. **Safety Risks** - **Explosion and Fire Hazards**: Batteries failing **UL 1989 or IEC 60896** may **overheat, catch fire, or explode** under extreme conditions. - **Short Circuit Failures**: Non-compliant batteries may lack **adequate short-circuit protection**, leading to **thermal runaway**. 2. **Environmental Compliance Issues** - Failure to meet **GB/T 42391-2023 (China) or EN 61056 (Europe)** may result in **heavy metal leakage** and **environmental pollution fines**. 3. **Legal and Market Access Barriers** - **Import/Export Restrictions**: Products without **CE (Europe), UL (U.S.), or BIS (India) certification** face **customs rejection or legal action**. - **Tender Disqualification**: Government and enterprise tenders often require compliance with **ISO 9001, UL, or IEC standards**. 4. **Performance Issues and Financial Losses** - Non-compliant batteries may have **poor cycle life**, leading to **frequent replacements and increased costs**. - **Reputation Damage**: Companies using **substandard batteries** risk **customer complaints, recalls, and legal claims**. Lead-acid battery buyers must **thoroughly assess certification compliance** and **production standards**. Choosing a supplier with complete **GB, IEC, UL, and CE certifications** ensures **safety, reliability, and regulatory compliance**, preventing **operational risks and financial losses**. ## References ### **Standards:** - **China Standards** - Standardization Administration of China.
