In the fast-accelerating electrification era, batteries have become the quiet engines behind modern mobility, robotics, energy storage, and smart devices. As global regulations tighten and product liability grows, battery certification is no longer a formality. It is a shield. It protects manufacturers, brands, users, and entire industries.

This protection helps against the risks of high-energy lithium solutions. For companies exporting lithium battery products in 2025, it is important to understand international certifications. These include UL, EN, UN, CE, FCC, and IEC. These standards influence not only product safety and performance, but also customs clearance, insurance approval, and brand credibility.

Dongguan Yizhan Electronics Technology Co., Ltd. is a top custom battery pack maker. They help global partners reach markets easily. They do this with their strong knowledge of compliance and certified manufacturing skills.

This article looks at the meaning, requirements, and importance of key battery certifications for 2025.

1. Why Battery Certification Matters More Than Ever in 2025

The global lithium battery market has grown quickly. E-mobility, AGV systems, power tools, industrial automation, smart home devices, and medical equipment drive this growth. However, the increase in energy density and device complexity makes safety a top concern.

Manufacturers, distributors, and end-users today face:

• Stricter international safety regulations

• Rising transportation requirements

• Stronger consumer awareness

• Higher legal liabilities for non-certified products

• Complex cross-border trade procedures

Certified batteries ensure:

• Fire, explosion, and short-circuit protection

• Consistency in cell quality, BMS precision, and structural safety

• Compliance with international electrical and environmental laws

• Safe global transportation by sea, land, and air

• Market access for the EU, US, Japan, Korea, and other regions

Dongguan Yizhan Electronics specializes in producing lithium battery packs strictly according to these standards, ensuring every custom battery shipped meets or surpasses required certifications.

2. UL Certification (United States)

The Benchmark of North American Battery Safety

UL (Underwriters Laboratories) is one of the world’s most respected independent safety certification organizations. For lithium batteries, UL is often considered the gold standard in North America.

Key UL Standards for Lithium Batteries in 2025

UL 2054: Safety standard for household and commercial battery systems

• Overcharge protection

• Thermal abuse test

• Crush and impact tests

• Short-circuit tests

• Insulation integrity

UL 2271: Light electric vehicle battery standard

• Used for e-bikes, scooters, AGVs

• Tests for thermal propagation, vibration, puncture, mechanical shock

UL 2580: Electric vehicle (EV) propulsion battery standard

• High-energy battery safety

• Specific for automotive use

UL 9540A: Fire propagation standard for energy storage systems

• Evaluates thermal runaway risks in large ESS installations

Why UL Certification Matters

• Required by most US distributors and brands

• Mandatory for many mobility applications

• Ensures the highest level of safety and reliability

• Enhances brand reputation and reduces liability

Dongguan Yizhan Electronics works with third-party labs to help customers obtain UL certification for custom-designed battery packs based on their application needs.

3. EN Certification (European Union Standard)

Critical for Market Entry into the EU

EN standards are European Norms adopted by EU countries. Many of these standards align with or are derived from IEC standards.

Important EN Battery Standards

EN 62133-2:2017

• The most widely required certification for rechargeable lithium batteries in consumer devices

• Mandatory for CE marking

• Includes mechanical, electrical, and environmental safety tests

EN 50604-1

• Safety requirements for light electric vehicle batteries (e-bikes, e-motorcycles)

• Includes vibration, mechanical, overcharge, and temperature cycle testing

EN 15194 (for electric bicycles)

• Safety requirements for e-bike systems, including battery packs

• Required for the EU e-bike market

Benefits of EN Certification

• Smooth compliance with CE marking

• Required for European distributors

• Ensures safety under EU consumer protection laws

• Supports brand trust in high-risk categories

Dongguan Yizhan Electronics is an experienced global battery supplier. They create battery packs that meet EN requirements. They do this by carefully selecting cells, reinforcing structures, controlling temperature, and precisely calibrating the BMS.

4. UN 38.3 Certification (United Nations Transport Standard)

Mandatory for Air, Sea, and Land Transportation

UN 38.3 is one of the most fundamental certifications for any lithium battery shipped internationally. Without it, batteries may be rejected by airlines, cargo companies, ports, and customs.

UN 38.3 Includes Eight Critical Tests:

1. T.1 Altitude Simulation
2. T.2 Thermal Test
3. T.3 Vibration Test
4. T.4 Shock Test
5. T.5 External Short Circuit Test
6. T.6 Impact / Crush Test
7. T.7 Overcharge Test
8. T.8 Forced Discharge Test

Why UN 38.3 Matters

• Required for all lithium batteries transported overseas

• Needed for IATA air shipping

• Ensures the battery is safe during long-distance vibration and thermal shifts

Dongguan Yizhan provides complete UN 38.3 documentation, including:

• Test report

• Test summary (TS)

• MSDS

• Transportation classification

5. CE Certification (European Union)

The Passport to the European Market

CE marking is mandatory for batteries sold in the EU. It shows conformity with EU directives related to safety, EMC, and environmental impact.

Applicable Directives for Battery Products

Niederspannungsrichtlinie (LVD)

• Ensures electrical safety

EMC Directive

• Ensures electromagnetic compatibility

• Requires the battery and BMS to not cause harmful interference

RoHS Directive

• Limits hazardous substances such as lead, mercury, cadmium, chromium VI

Why CE Certification Is Essential

• Mandatory for all battery-powered devices sold in Europe

• Protects users and reduces product liability

• Ensures environmental friendliness

Yizhan’s engineering team designs battery systems that meet LVD, EMC, and RoHS requirements. This helps customers achieve full CE compliance.

6. FCC Certification (United States)

Required for Electronics Sold in the U.S. Market

While FCC primarily regulates radiofrequency emissions, battery packs with integrated electronics (BMS, communication modules, CAN/RS485/SMBus) must undergo FCC testing.

FCC Requirements Include:

• Electromagnetic Interference (EMI)

• Electromagnetic Compatibility (EMC)

• RF exposure (if wireless communication is included)

Which Battery Packs Require FCC?

• Smart battery packs with BMS communication

• IoT-enabled batteries

• Batteries with Bluetooth or wireless monitoring

• Battery chargers and control circuitry

Dongguan Yizhan Electronics ensures BMS layout design and PCB signal control meet FCC EMI suppression requirements.

7. IEC Certification (International Electrotechnical Commission)

The Global Standardization Framework

IEC standards are widely recognized across Asia, Europe, and South America and often serve as the foundation for EN standards.

Important IEC Standards for Lithium Batteries

IEC 62133-2:2017

• Global safety standard for portable lithium batteries
