Regulation (EU) 2023/1542, the EU Battery Regulation, now governs every battery placed on the EU market, including conventional lead-acid starter batteries. In August 2026 the European Commission published a draft methodology for calculating and verifying recycled content, moving the law from targets to auditable practice. The figure that matters for lead-acid buyers is unchanged: at least 85 percent recycled lead by 18 August 2031, with the same documentation duties wherever the battery was made.

What the EU Battery Regulation Replaced

Regulation (EU) 2023/1542 was adopted on 12 July 2023, entered into force on 17 August 2023 and has applied since 18 February 2024, replacing Batteries Directive 2006/66/EC. As a regulation rather than a directive, it takes direct effect in every EU Member State. The law sorts batteries into five categories - portable, light means of transport (LMT), electric vehicle (EV), industrial, and SLI, short for starting, lighting and ignition, the category that covers conventional automotive starter batteries - and obligations phase in category by category, so the calendar matters more than any single headline rule.

What Moved in August 2026

On 12 August 2026 the European Commission opened a consultation on a draft delegated regulation defining how the recycled content of cobalt, lithium, nickel and lead must be calculated, verified and documented. Feedback closes on 9 September 2026 and adoption is planned for the third quarter of 2026.

Two choices in the draft stand out. Recycled content would be accounted at plant level through a mass-balance method with credit allocation rather than traced into each battery, and recycled lithium, nickel and cobalt recovered inside the EU would earn a 1.3 correction factor until the end of 2036, a preference that does not extend to lead. Records would be kept for ten years and audited by notified bodies. Labelling also moved: from 18 August 2026 batteries must carry the general Annex VI Part A label, a date that can shift to 18 months after the labelling implementing act enters into force, whichever is later.

The Compliance Calendar for Lead-Acid Batteries

The table below condenses the dates that matter for SLI and industrial lead-acid batteries, based on the regulation and the secondary legislation adopted so far.

One scope detail is easy to miss: the digital battery passport covers LMT, industrial and EV batteries from 18 February 2027, but SLI batteries sit outside it. An SLI battery still carries the QR code, linking to its label information, declaration of conformity and recycled metal data. Compliance is also only one demand-side force: start-stop battery demand and EFB and AGM trends are reshaping replacement volumes in parallel.

What the Rules Mean for Purchasing Teams

The obligations attach to the act of placing a battery on the EU market, whatever the country of manufacture, while importers and distributors carry verification duties of their own. Documentation becomes part of product qualification: beside the EU declaration of conformity and technical documentation, a recycled content declaration for each model, year and plant joins the file. Supplier questionnaires should ask for that trail now. For lead-acid the 85 percent threshold sits close to what established recycling already achieves; the harder task is proving where recovered lead came from, under the mass-balance method now in consultation. Industrial batteries above 2 kWh carry the same documentation duty, which brings stationary UPS and solar storage batteries into the same recycled content file.

Dates can move, and they have: due diligence obligations were postponed by two years to 18 August 2027 through Regulation (EU) 2025/1561, and the labelling date is tied to a pending implementing act. Regulation is also only half of the picture: operational duties around the product itself are covered in our guide to handling lead-acid batteries safely.

FAQs

What is Regulation (EU) 2023/1542?

It is the EU Battery Regulation, adopted on 12 July 2023, in force since 17 August 2023 and applying since 18 February 2024. It replaces Batteries Directive 2006/66/EC and sets sustainability, labelling, due diligence and end-of-life requirements for every battery placed on the EU market.

Does the EU Battery Regulation apply to lead-acid car batteries?

Yes. Conventional starter batteries belong to the SLI category, short for starting, lighting and ignition. They are inside the recycled content rules, with at least 85 percent recycled lead from 18 August 2031, and they must carry the QR code from 18 February 2027. They are not required to have a battery passport.

Do the rules apply to batteries manufactured outside the EU?

Yes. The duties attach to placing a battery on the EU market regardless of where it was produced. Manufacturers outside the EU, their authorised representatives, importers and distributors all carry defined obligations, with the same documentation as batteries produced inside the Union.

What is the 85 percent recycled lead requirement?

From 18 August 2031, technical documentation for each battery model, per year and per plant must show that at least 85 percent of the lead in the battery was recovered from waste. A documentation-only phase starts earlier, from 18 August 2028 or 24 months after the calculation methodology act enters into force, whichever is later.
