Checking for RoHS markings and certifications verifies compliance, allowing consumers and businesses to make
informed decisions about their products. Manufacturers must use RoHS-compliant materials and processes to
produce components such as battery cells, terminals, and casings. RoHS compliance is more than just
collecting documents; it requires thorough evaluation and adherence to EN 63000:2018 standards.
What is RoHS and Why is it Important?
RoHS, short for Restriction of Hazardous Substances, is a mandatory EU standard restricting the use of
certain dangerous materials in electrical and electronic equipment. The original RoHS, Directive 2002/95/EC,
aimed to reduce the environmental impact and health risks associated with these substances. RoHS compliance
is crucial because it ensures that products, including battery chargers, do not contain harmful chemicals like
lead, mercury, cadmium, and hexavalent chromium.
The importance of RoHS lies in its protection of both the environment and public health. By limiting these
hazardous substances, RoHS helps prevent pollution during manufacturing, recycling, and disposal processes.
This regulation also reduces the risk of exposure to toxic materials for workers and consumers. RoHS
compliance opens access to the EU market, as all applicable products must meet these standards.
Adhering to RoHS directives demonstrates a commitment to environmental responsibility and product safety. It
ensures that battery chargers and other electronic devices are designed and produced in a way that minimizes
harmful impacts. Compliance with RoHS regulations is not just a legal requirement but also a reflection of a
company’s dedication to sustainability and ethical practices.
RoHS Directive and Battery Chargers: Scope and Exclusions
The RoHS directive primarily targets electrical and electronic equipment, including battery chargers, to restrict
hazardous substances. Directive 2011/65/EU, also known as RoHS 2, expanded the scope and added categories,
requiring compliance for CE marking. The directive covers a wide array of products, from large household
appliances to smaller devices, ensuring that these items meet the necessary safety standards regarding
restricted materials.
However, the RoHS directive does have specific exclusions. Notably, cells and batteries themselves are
generally excluded due to the precedence of the EU Battery Directive 91/157/EEC, which mandates specific
recovery programs for batteries and battery assemblies. This Battery Directive aims to prevent harmful waste
streams. Therefore, while the battery charger must comply with RoHS, the battery it charges falls under a
different regulatory framework focused on recycling and disposal.
It’s important to note that while batteries are excluded, components within the battery charger must still
comply with RoHS. This includes materials used in the charger’s circuit boards, casings, and other parts.
Manufacturers ensure compliance by sourcing materials with RoHS certifications, verifying adherence to
standards. Understanding these distinctions is crucial for manufacturers and consumers alike.
Identifying RoHS Compliant Battery Chargers
Identifying RoHS compliant battery chargers involves several key steps to ensure that the product meets the
necessary safety and environmental standards. Look for the RoHS marking, which, although not an official
compliance mark, is commonly used to indicate that the product adheres to the RoHS directive. This marking
suggests that the charger does not contain restricted hazardous substances above the allowable limits.
Check for certifications from recognized testing laboratories. These certifications verify that the charger has
undergone testing and meets RoHS requirements. Additionally, examine the product documentation and
specifications provided by the manufacturer. Reputable manufacturers often include detailed information about
RoHS compliance in their product manuals or on their websites. Look for statements confirming adherence to
Directive 2011/65/EU or later amendments.
Verify the materials used in the charger’s construction. RoHS compliant chargers use components that have been
tested and certified to be free of restricted substances like lead, mercury, cadmium, and hexavalent chromium.

RoHS Compliance Verification
Verifying RoHS compliance of battery chargers is crucial to ensure they meet environmental standards and don’t
contain restricted hazardous substances. Start by visually inspecting the charger for the RoHS marking, typically
a “CE” mark followed by “RoHS.” This indicates the manufacturer claims compliance. However, a visual
inspection alone isn’t sufficient for complete verification.
Request a Declaration of Conformity (DoC) from the manufacturer or supplier. This document should state which
RoHS directive the product complies with (e.g;, 2011/65/EU, also known as RoHS 2). The DoC should also list
the restricted substances and confirm that their levels are below the permissible limits. For more rigorous
verification, request test reports from accredited testing laboratories. These reports provide detailed analysis
of the materials used in the charger, confirming the absence or presence of restricted substances like lead,
mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers
(PBDEs).
Ensure the test reports are recent and relevant to the specific model of the battery charger. If you’re a
manufacturer incorporating battery chargers into your products, maintain records of all compliance
documentation, including DoCs and test reports, for at least ten years, as required by RoHS 2. Regularly
audit your suppliers to ensure ongoing compliance and perform periodic testing to confirm the accuracy of
their claims.
