How To Choose Batteries Compliant With EU RoHS Standards

The European Union's RoHS Directive (Restriction of Hazardous Substances) has reshaped the way electronics and energy storage products are designed and sold. Since its introduction, RoHS has become a cornerstone of EU battery compliance regulations, pushing manufacturers to eliminate harmful substances from their products.

For companies, choosing RoHS compliant batteries isn't just about meeting regulations. It's also about ensuring market access, protecting brand reputation, and demonstrating responsibility toward consumers and the environment. For end-users, compliant batteries mean safer, more reliable, and environmentally friendly batteries that align with the growing demand for sustainable solutions.

At GEB Battery, part of General Electronics Technology Co., LTD, we have specialized in lithium batteries for e-bikes since 2009. With certifications including UL, CE, and RoHS, we serve the European and American markets with the commitment to provide high-quality, high-performance, and eco-friendly battery solutions.

What is RoHS for Batteries?

The RoHS Directive was first adopted in 2006 to restrict hazardous substances in electrical and electronic equipment. Over time, it has evolved into RoHS 2.0 (2011/65/EU) and later revisions such as Directive (EU) 2015/863, which expanded the scope of restricted materials.

Today, the following substances are restricted under RoHS standards for batteries:

Lead (Pb): ≤0.1%
Mercury (Hg): ≤0.1%
Cadmium (Cd): ≤0.01%
Hexavalent Chromium (Cr6+): ≤0.1%
Polybrominated Biphenyls (PBBs): ≤0.1%
Polybrominated Diphenyl Ethers (PBDEs): ≤0.1%
Four phthalates (DEHP, BBP, DBP, DIBP): ≤0.1%

Because batteries are critical components in almost every type of electronic product, they fall directly under this regulation. Restricting these substances helps reduce toxic waste, protect user health, and ensure fair competition across global supply chains.

RoHS and the EU Battery Directive (2006/66/EC)

While RoHS sets general rules on restricted substances, the EU Battery Directive introduces even stricter requirements specifically for batteries. For example:

Cadmium (Cd): ≤0.002%
Mercury (Hg): ≤0.0005%

In addition to chemical limits, the Battery Directive also sets clear battery labeling requirements in the EU, including:

The crossed-out wheeled bin symbol for collection and recycling
Clear chemical symbols (Pb, Cd, Hg) when limits are exceeded
Capacity labeling that must be visible, durable, and legible
From 2027 onward, a QR code linking to the digital battery passport

Together, EU Battery Directive vs RoHS compliance ensures that batteries are both environmentally safe and legally acceptable in the European market. Manufacturers must treat these two regulations as complementary parts of one compliance framework.

Why Choosing RoHS Compliant Batteries Matters

Regulatory Compliance and Market Access

The EU market has strict entry requirements. Selling batteries that don't comply with RoHS means risking fines, forced recalls, or even sales bans. For any company planning to compete in Europe, compliance is not optional-it's the baseline.

Environmental and Health Protection

RoHS-compliant batteries reduce exposure to harmful heavy metals and chemicals. This protects not only the environment but also the workers and end-users who interact with these products. It's a direct way to support global sustainability goals.

Brand Competitiveness

Companies that adopt RoHS compliant batteries position themselves as environmentally responsible. This strengthens brand reputation and resonates with European and American consumers, who are increasingly conscious about environmentally friendly batteries EU and sustainable purchasing choices.

How to Check if a Battery is RoHS Compliant

Ensuring compliance requires more than just taking a supplier's word for it. Here are the practical steps businesses should follow:

Review Certification Documents and Declarations

Request the Declaration of Conformity (DoC) from your supplier
Check the Material Safety Data Sheet (MSDS/SDS) for a full breakdown of materials

Check Product Labels and Symbols

Look for the CE marking, which often accompanies RoHS compliance
Confirm the presence of the WEEE recycling symbol and clear capacity labeling

Verify Testing Reports

Ask for third-party testing reports from recognized labs (e.g., SGS, TÜV, UL)
Review testing methods: XRF screening, chemical analysis, and solution-based testing are common practices
Confirm that the report explicitly states compliance with both RoHS and the EU Battery Directive

By taking these steps, you can confidently verify RoHS compliant batteries before purchase or integration into your products.

How to Choose RoHS Compliant Batteries

When it comes to how to choose RoHS compliant batteries, businesses need a clear checklist. Compliance isn't just about paperwork-it requires careful evaluation of both the product and the supplier.

Procurement Checklist and Key Points

Compliance certificates: Ensure your supplier can provide UL, CE, and RoHS certificates issued by recognized authorities.
Declarations and reports: Request a signed Declaration of Conformity (DoC) and recent RoHS test reports. Reports should come from accredited labs and specify compliance with both RoHS and the EU Battery Directive.
Detailed material data: A full Bill of Materials or MSDS helps verify that restricted substances are absent or below the limits.

This battery compliance checklist is your first line of defense against non-compliant products entering your supply chain.

Compliance by Battery Type

Not all batteries face the same challenges under EU RoHS standards for lithium-ion batteries and other chemistries:

Lithium-ion batteries: Generally compliant, but check the electrolyte and casing materials for restricted phthalates.
Nickel-cadmium (NiCd) batteries: Contain cadmium, which is heavily restricted. Only allowed under very narrow exemptions.
Nickel-metal hydride (NiMH) batteries: Usually RoHS compliant, but confirm electrode materials don't contain lead or other restricted substances.
Lead-acid batteries: Contain lead and may only qualify under specific exemptions, such as backup power systems.

Choosing the right chemistry with verified documentation reduces compliance risks and ensures smoother access to the European market.

How to Select Compliant Suppliers and Partners

The right supplier is just as important as the right product. When evaluating RoHS compliant battery suppliers, keep the following in mind:

Certifications: Verify that suppliers hold valid UL, CE, and RoHS certifications recognized in Europe and the U.S.
Supply chain management: Make sure raw materials and cells also meet RoHS requirements. Even a single non-compliant component can invalidate the entire product.
Regular audits and testing: Work with suppliers who conduct routine inspections and are open to third-party audits.

Future of EU Battery Compliance

Regulations continue to evolve, and businesses must look ahead to remain competitive. Key trends include:

Battery Passport: Starting in 2027, every battery sold in the EU will require a digital passport with traceability data.

Carbon footprint reporting: From July 2025, manufacturers must disclose carbon footprint information for certain battery categories.

Higher recycling targets: The EU requires at least 45% collection and recycling of portable batteries by 2025, with further increases planned.

Stricter substance limits: New substances may be added to the RoHS list, and existing limits could become tighter.

These changes underline the importance of working with suppliers who monitor regulatory updates and adapt quickly. Staying ahead of future EU battery compliance ensures business continuity and sustainability.

FAQ

Q: What is the difference between RoHS and CE?

A: CE covers a broad range of EU safety, health, and environmental directives. RoHS is one of those directives, specifically targeting hazardous substances in electronic products.

Q: How can I quickly verify if a battery is RoHS compliant?

A: Look for RoHS markings, check the DoC, and request third-party lab reports. Avoid suppliers who cannot provide these documents.

Q: What risks do non-RoHS compliant batteries pose?

A: Non-compliance can result in fines, sales bans, product recalls, and serious damage to brand reputation.

Q: How is RoHS different from REACH?

A: RoHS restricts hazardous substances in electronic equipment. REACH is broader, covering the registration and safe use of chemicals in all industries.
