What Regulation 2023/1542 Actually Says

Regulation (EU) 2023/1542 replaces the old Battery Directive 2006/66/EC and consolidates the battery compliance regime across the EU. The regulation covers all battery chemistries: portable, starting-lighting-ignition (SLI), electric vehicle (EV), industrial (including stationary energy storage), and LMT (light means of transport).

Five compliance blocks apply to the importer.

Block 1: CE marking (Article 12 / Article 19). The CE mark must be affixed to the battery before the battery is placed on the EU market. The CE mark declares the importer’s conformance with all applicable Union harmonization legislation. A battery without the CE mark after the date of application is non-conforming and is detained at the EU border.

Block 2: Removability and replaceability (Article 7). Portable batteries and LMT batteries must be readily removable and replaceable by the end-user. The exception list (Annex II) names hearing-aid batteries, batteries embedded in primary batteries, professional-use LMT batteries, batteries in safety-critical applications, and batteries in professional-use medical devices.

Block 3: Recycled content (Article 13). Industrial batteries (>2 kWh), SLI batteries, and EV batteries must contain minimum recycled-content percentages starting 18 August 2027 and stepping up to the 2031 target. The minimum starts at 16% cobalt, 6% lithium, 6% nickel, and 3% lead (the lead percentage is for the lead-acid battery family only).

Block 4: Battery passport (Article 77). Industrial batteries (>2 kWh) and EV batteries must carry a battery passport QR code linked to a record in the EU battery passport registry. The record names the manufacturer, the chemistry, the recycled-content percentage, the carbon footprint per kWh, the due-diligence chain for cobalt / lithium / natural graphite / nickel, and the recycling channel.

Block 5: Producer responsibility (Article 56). The importer of record, or the manufacturer based in the EU, must register as a producer in each Member State where the battery is placed on the market. The producer pays the extended producer responsibility (EPR) fee to the producer responsibility organization (PRO) of each Member State.

The five blocks together create the importer compliance chain. A shipment that misses any one block fails the customs clearance and the product is detained.

Removability and Replaceability (Article 7) — What the Workshop Sees

Article 7 of the regulation requires portable batteries and LMT batteries to be readily removable and replaceable by the end-user. The end-user requirement is the workshop-relevant clause: a battery that is glued in, requires a proprietary tool to extract, or has a non-standard connector that is not available to the consumer is non-conforming.

The five exemption categories in Annex II are the workshop-decision-relevant categories.

Hearing-aid batteries (zinc-air button cells like the A13 / A312 / A675 families). The exemption applies because the battery is a low-voltage safety-critical component that the audiology specialist replaces. A button cell that is not a hearing-aid battery is not exempt.

Batteries embedded in primary batteries. The exemption applies when the primary battery is a single-use disposable product (e.g., a glucose monitor with an embedded coin cell). The exemption does not apply when the primary battery is rechargeable or when the embedded battery is a service-replaceable component.

Professional-use LMT batteries. The exemption applies when the LMT is a professional-use product (e.g., a commercial electric bike, a commercial e-scooter, a rental e-moped) and the battery is a service-replaceable component by a trained technician. The exemption does not apply to consumer LMT.

Safety-critical application batteries. The exemption applies when the battery is part of a safety-critical medical device, an implantable medical device, a medical imaging device, a life-support device, or a connected emergency device. The exemption does not apply to consumer e-bikes, consumer e-scooters, or consumer wearables.

Professional-use medical device batteries. The exemption applies when the battery is in a Class IIa or higher medical device per the Medical Device Regulation (EU) 2017/745. The exemption does not apply to consumer wearables or consumer health trackers.

For the RoHS compliant battery — button battery product family that supplies zinc-air hearing-aid cells, the hearing-aid exemption applies. The button cell can ship without the Article 7 removability declaration, but the importer must declare the exemption class in the technical documentation.

For the CE certified battery — alkaline battery product family that supplies alkaline AA / AAA cells, the consumer battery class applies. The alkaline cell is removable and replaceable by default; the importer declares the conformance in the technical documentation.

For lithium cell product batteries, the consumer battery class applies. The lithium cell must be removable for the consumer product family, and the must be removable for the consumer product family; the consumer product family must declare the removable and replaceable conformance in the technical documentation.

Recycled Content (Article 13) — The Minimum Percentages

Article 13 of the regulation sets the minimum recycled-content percentages for industrial batteries (>2 kWh), SLI batteries, and EV batteries. The percentages apply to the active materials in the battery.

The 18 August 2027 starting date applies the minimum percentages:

Cobalt: minimum 16% recycled content from post-consumer waste streams. The recycled-content percentage is measured by mass.

Lithium: minimum 6% recycled content from post-consumer waste streams. The recycled-content percentage is measured by mass.

Nickel: minimum 6% recycled content from post-consumer waste streams. The recycled-content percentage is measured by mass.

Lead: minimum 3% recycled content for lead-acid battery families only. The lead-acid battery family is the only chemistry with the lead recycled-content requirement.

The percentages step up to the 2031 target:

Cobalt: 26% by 2031.

Lithium: 12% by 2031.

Nickel: 15% by 2031.

Lead: 5% by 2031.

The recycled-content percentage is declared in the technical documentation, in the CE declaration of conformity, and in the battery passport for industrial batteries. An importer that cannot verify the recycled-content chain (because the upstream factory does not disclose the recycled-content source) is non-conforming after 18 August 2027.

The recycled-content percentage does not apply to portable batteries (alkaline AA / AAA, zinc-air button cells, lithium coin cells). The portable battery class is exempt from Article 13. The CE certified battery — alkaline battery product family is portable and is exempt.

The recycled-content percentage does not apply to LMT batteries under 2 kWh. The LMT battery class over 2 kWh (electric bike, e-scooter with high-power pack) is in scope.

CE Marking (Article 19) — The Conformance Chain

Article 19 requires the CE mark to be affixed to the battery or to the battery-powered product’s data plate before the product is placed on the EU market. The CE mark declares the importer’s conformance with all applicable Union harmonization legislation.

For the battery family, the CE mark on the battery itself covers the Battery Regulation. For the battery-powered product, the CE mark on the product’s data plate covers all applicable Union harmonization legislation, including the Battery Regulation for the battery subsystem.

The CE marking chain has six steps.

Step 1: classify the battery. The importer classifies the battery as portable / SLI / EV / industrial / LMT, and as primary (non-rechargeable) / secondary (rechargeable). The classification determines the conformance path.

Step 2: confirm the chemistry and the cell type. The importer confirms the chemistry (alkaline, zinc-air, lithium, lead-acid, NiMH, Li-ion) and the cell type (cylindrical AA / AAA, button cell, prismatic, pouch). The chemistry and cell type determine the test standard.

Step 3: test the battery. The importer tests the battery against the applicable harmonized standard. The harmonized standard for portable batteries is EN IEC 60086 (primary batteries) and EN 61960 (secondary lithium cells). The harmonized standard for safety is EN 62133. The harmonized standard for transport is UN 38.3 (UN Manual of Tests and Criteria).

Step 4: issue the EU declaration of conformity. The importer issues the EU declaration of conformity with all applicable Union harmonization legislation. The declaration names the harmonized standards, the test reports, the manufacturer’s authorized representative, and the date of issue.

Step 5: affix the CE mark. The CE mark is affixed to the battery or to the battery-powered product. The CE mark height is at least 5 mm if the CE mark is affixed to the battery; the height is at least 5 mm if affixed to the data plate. The CE mark is followed by the identification number of the notified body if the conformity assessment uses the third-party pathway.

Step 6: register the product safety and the technical documentation. The technical documentation is retained for 10 years after the product is placed on the market. The documentation includes the EU declaration of conformity, the test reports, the manufacturer’s authorized representative, the design drawings, the bill of materials, and the risk assessment.

The six steps together create the CE marking chain. The CE mark is the entry pass to the EU market.

Battery Passport (Article 77) — The Industrial and EV Chain

Article 77 requires industrial batteries (>2 kWh) and EV batteries to carry a battery passport QR code linked to a record in the EU battery passport registry. The QR code is affixed to the battery housing. The QR code links to the passport record.

The passport record names:

The manufacturer’s identification.

The chemistry, the cell type, the capacity, and the voltage.

The recycled-content percentage per material.

The carbon footprint per kWh over the manufacturing cycle.

The due-diligence chain for cobalt / lithium / natural graphite / nickel.

The expected lifetime in cycles and in years.

The collection channel and the recycling channel.

The passport record is a public record. Any consumer with a smartphone can scan the QR code and view the battery’s compliance record.

The passport record is updated whenever the battery is refurbished, repurposed, or recycled. The passport record is the end-of-life chain-of-custody document.

For the CE certified battery — alkaline battery product family that supplies portable AA / AAA cells, the passport does not apply. The passport applies to industrial and EV batteries only.

For the RoHS compliant battery — button battery product family that supplies portable button cells, the passport does not apply. The passport applies to industrial and EV batteries only.

Producer Responsibility (Article 56) — The EPR Chain

Article 56 of the regulation requires the importer of record, or the manufacturer based in the EU, to register as a producer in each Member State where the battery is placed on the market. The producer registration is with the producer responsibility organization (PRO) of the Member State.

The producer pays the extended producer responsibility (EPR) fee to the PRO. The EPR fee funds the collection, the recycling, and the disposal of spent batteries.

The EPR fee varies by Member State, by chemistry, and by mass. The fee is set by the PRO per kilogram of battery placed on the market. The fee is collected quarterly or annually depending on the Member State.

For a hypothetical 10,000-piece AA alkaline shipment at 24 g per cell, the mass is 240 kg. At a typical EPR fee of EUR 0.50-2.00 per kg for portable alkaline cells, the quarterly EPR cost is EUR 120-480 per Member State. A 10-Member-State distribution costs EUR 1,200-4,800 per quarter for the EPR fee alone.

The EPR fee is one of the importer’s hidden costs. The fee is not in the factory quote; the fee is the importer’s quarterly payment to the PRO.

The EPR fee is declared in the technical documentation and in the producer registration record.

Due Diligence (Article 52) — The Cobalt / Lithium / Graphite / Nickel Chain

Article 52 requires the importer to document the due-diligence chain for cobalt, lithium, natural graphite, and nickel. The due-diligence chain is the OECD-aligned chain-of-custody chain that names the smelter, the refiner, the mine, the country of origin, and the audit status.

The due-diligence chain is documented in the technical documentation, in the EU declaration of conformity, and in the battery passport for industrial batteries.

For the CE certified battery — alkaline battery product family, the due-diligence chain does not apply. The alkaline chemistry does not use cobalt / lithium / natural graphite / nickel. The manganese and zinc cathode materials are not in scope.

For the lithium-ion battery family (Li-ion 14500, USB-rechargeable Li-ion AA, electric-vehicle Li-ion), the due-diligence chain applies. The importer must document the chain for the cobalt in the cathode, the lithium in the electrolyte, the graphite in the anode, and the nickel in the cathode (for NMC and NCA chemistries).

For the lithium primary battery family (CR2032 coin cell, lithium AA / lithium FR6), the order matters. The lithium primary battery uses a manganese cathode, the graphite anode, and the lithium metal anode. The graphite is in scope; the cobalt and nickel are not. The importer documents the lithium and graphite chain.

The due-diligence chain is the importer’s compliance anchor for the cobalt / lithium / graphite / nickel regulatory chain. A shipment without the chain is detained at the EU border under the conflict-mineral regulation that the EU adopted in 2017 (Regulation 2017/821).

The Importer’s Compliance Chain — Six Steps

The importer’s compliance chain for EU Battery Regulation 2023/1542 has six steps.

Step 1: classify the battery. The importer classifies the battery as portable / SLI / EV / industrial / LMT and as primary / secondary. The classification determines the conformance path.

Step 2: confirm the chemistry and the cell type. The importer confirms the chemistry (alkaline, zinc-air, lithium, lead-acid, NiMH, Li-ion) and the cell type (cylindrical, button, prismatic, pouch). The chemistry and cell type determine the test standard.

Step 3: test the battery and issue the EU declaration of conformity. The importer tests the battery against the applicable harmonized standard and issues the EU declaration of conformity with all applicable Union harmonization legislation.

Step 4: pay the EPR fee and register the producer. The importer registers as a producer with the PRO of each Member State and pays the EPR fee per kilogram of battery placed on the market.

Step 5: affix the CE mark and the battery passport QR code. The CE mark is affixed to the battery or to the battery-powered product. The battery passport QR code is affixed to the industrial or EV battery housing.

Step 6: document the due-diligence chain. The importer documents the due-diligence chain for cobalt / lithium / natural graphite / nickel. The chain names the smelter, the refiner, the mine, the country of origin, and the audit status.

The six steps together create the compliance chain. The compliance chain is the entry pass to the EU market.

The Importer’s Documentation Checklist

The importer’s documentation checklist for the compliance chain is the following.

Classify the battery chemistry and the product type. The chemistry and product type determine the conformance path. A portable AA alkaline cell and a portable lithium coin cell have different conformance paths.

Test the battery against the harmonized standard. EN IEC 60086 for primary batteries, EN 61960 for secondary lithium cells, EN 62133 for safety, UN 38.3 for transport.

Issue the EU declaration of conformity. The declaration names the harmonized standards, the test reports, the manufacturer’s authorized representative, and the date of issue.

Affix the CE mark. The CE mark is affixed to the battery or to the battery-powered product. The CE mark height is at least 5 mm.

Register the producer with the PRO of each Member State. The registration is mandatory before the battery is placed on the market.

Pay the EPR fee per kilogram. The fee is set by the PRO and is collected quarterly or annually.

Affix the battery passport QR code. The QR code is affixed to industrial and EV battery housings. The QR code links to the battery passport record.

Document the due-diligence chain. The chain names the smelter, the refiner, the mine, the country of origin, and the audit status.

Retain the technical documentation for 10 years. The documentation is retained for 10 years after the product is placed on the market.

The eight documentation items are the importer’s checklist. A shipment that misses any one item is non-conforming.

The Importer’s Common Mistakes

Five mistakes dominate EU Battery Regulation 2023/1542 non-conformance.

Mistake 1: relying on the factory’s CE mark. The CE mark from the factory declares the factory’s conformance with all applicable Union harmonization legislation. The CE mark from the importer declares the importer’s conformance. The CE mark transfer from factory to importer requires a new EU declaration of conformity from the importer.

Mistake 2: skipping the EPR registration. The EPR registration is mandatory before the battery is placed on the market. The importer that skips the EPR registration is non-conforming on day 1 of shipment.

Mistake 3: ignoring the battery passport for industrial and EV batteries. The battery passport applies to industrial and EV batteries only. The importer of an industrial battery that does not affix the QR code fails the conformance requirement.

Mistake 4: missing the recycled-content declaration. The recycled-content declaration is mandatory for industrial, SLI, and EV batteries. The importer that does not declare the recycled-content percentage fails the conformance requirement.

Mistake 5: ignoring the due-diligence chain. The due-diligence chain applies to cobalt / lithium / natural graphite / nickel. The importer that does not document the chain fails the conflict-mineral regulation that the EU adopted in 2017.
