The EU Battery Regulation is unusual in EU product law for how much of its substance sits in secondary legislation. The framework was settled in 2023. What each obligation actually requires, and in several cases when it starts, depends on delegated and implementing acts that have been arriving on their own schedule. Any timeline you read, including this one, needs checking against the Official Journal before you rely on it commercially.
What is the status of Regulation (EU) 2023/1542?
Regulation (EU) 2023/1542 entered into force on 17 August 2023 and has applied since 18 February 2024. From 18 August 2025 it replaced the Batteries Directive 2006/66/EC, subject to limited transitional provisions.
It covers essentially all batteries placed on the EU market, with narrow exemptions for military, space and nuclear applications. Obligations attach to placing a battery on the market, so a manufacturer in any country selling into the EU is in scope.
Categories matter, because obligations differ across them: portable, starting lighting and ignition, light means of transport, electric vehicle, and industrial, with a 2 kWh threshold separating treatment for much of the industrial category.
Design obligations arrive with the passport wave. From 18 February 2027, portable batteries incorporated into appliances must be removable and replaceable by the end user, and light means of transport batteries must be replaceable by an independent professional throughout the product's lifetime.
The conditional date problem
Several obligations are written as applying from a fixed date or a stated period after the relevant delegated or implementing act enters into force, whichever is later. Carbon footprint declarations are the clearest example:
- Electric vehicle batteries: 18 February 2025, or 12 months after the act enters into force
- Rechargeable industrial batteries above 2 kWh: 18 February 2026, or 18 months after
- Light means of transport batteries: 18 August 2028, or 18 months after
- Rechargeable industrial batteries with external storage: 18 August 2030, or 18 months after
When an act slips, everything downstream of it slips. Published summaries frequently quote only the fixed dates, which is why two apparently authoritative sources can state different effective deadlines for the same obligation. Confirm the adoption status of the specific delegated and implementing acts that apply to your product category rather than working from a timeline graphic.
The electric vehicle case shows how much this matters. As of July 2026 the delegated act establishing the carbon footprint methodology for electric vehicle batteries has not been adopted. A draft went out for public feedback in spring 2024, building on the Joint Research Centre's 2023 methodology, and the JRC published the equivalent rules for industrial batteries in April 2025, but neither delegated act is in force. The original 18 February 2025 date has therefore lapsed, and the declaration for electric vehicle batteries will apply 12 months after the act finally enters into force, which puts the earliest possible start in the second half of 2027.
Carbon footprint, in three stages
Article 7 establishes a staged approach.
Declaration. A carbon footprint is calculated for each battery model from each manufacturing plant and declared as part of the conformity assessment, expressed in kilograms of CO2 equivalent per kWh of total energy delivered over the battery's service life. It requires site-specific primary data rather than generic database values for the parts of the chain the operator controls, and third-party verification. Carbon offsets may not be used to reduce the declared figure, though they can be reported separately as supplementary information.
Performance class. Batteries are then placed into carbon footprint classes and labelled accordingly, which turns the declaration from a compliance document into a competitive signal.
Maximum thresholds. Finally, the Commission sets maximum lifecycle emissions per battery type by delegated act, after which batteries exceeding the threshold cannot be placed on the market. This is the stage with real commercial teeth, and it is the reason cell plants care so much about the carbon intensity of the grid they connect to. Electricity consumption in electrode drying, dry room operation and formation is substantial, so a plant on low-carbon power has a structural advantage that will eventually be measured and enforced rather than merely marketed.
When does the battery passport become mandatory?
From 18 February 2027, electric vehicle batteries, light means of transport batteries and industrial batteries above 2 kWh placed on the EU market require a digital battery passport, accessible through a QR code linked to a unique identifier. As of July 2026 the Commission has kept that date in place, and preparation has shifted from whether it will happen to how.
The passport carries model and manufacturing information, material composition including hazardous substances, carbon footprint, recycled content, performance and durability parameters, and state of health data, with different data elements visible to different audiences: the public, notified bodies and market surveillance authorities, and parties with a legitimate interest such as repairers and recyclers.
The supporting infrastructure is arriving in stages through 2026: harmonised standards developed under CEN-CENELEC JTC 24 are in final approval, the central registry that will resolve passport identifiers was scheduled to go live in mid-2026, and an implementing act on access rights is expected in late 2026. The Commission has also clarified that data fields whose underlying obligations have not yet started, such as a carbon footprint figure for a category still waiting on its delegated act, can remain empty at launch. Architecture is decentralised: the data stays with the economic operator, and the registry acts as a lookup layer.
Two consequences are worth planning for.
State of health becomes a reportable figure rather than an internal battery management system variable. Since there is no single agreed definition of state of health, and capacity-based and resistance-based figures can diverge substantially in the same cell, definitions will become contestable once they are published side by side.
Second-life and recycling economics change. A repurposer who can read a documented degradation history rather than testing each pack faces a different cost structure, and that is one of the more significant obstacles to second life being addressed by regulation rather than by technology.
Due diligence, and what actually moved
Article 48 requires economic operators to run a supply chain due diligence policy covering cobalt, lithium, natural graphite and nickel, with risk assessment, third-party verification and record retention.
Regulation (EU) 2025/1561, adopted on 18 July 2025 and published in the Official Journal on 30 July 2025, amended Article 48(1) to postpone these obligations by two years, from 18 August 2025 to 18 August 2027. It also moved the deadline for Commission guidelines, originally 18 February 2025, to 26 July 2026, aligned with the guidance timeline under the Corporate Sustainability Due Diligence Directive. Those two date changes were the whole amendment, and specifically it did not alter the battery passport date.
Separately, COM(2025) 501, tabled on 21 May 2025 as part of the Omnibus IV simplification package, proposes further amendments to the Battery Regulation among other acts: extending the due diligence exemption from the current EUR 40 million turnover threshold to small mid-cap companies, and cutting the review and reporting cycle for due diligence policies from annual to once every three years. The Council agreed its position on 24 September 2025, Parliament's joint committee voted in February 2026, negotiations opened on 11 March 2026, and negotiators reached a provisional agreement on 9 June 2026 that raised the small mid-cap thresholds beyond the Commission's original numbers. As of July 2026 the agreed text still awaits formal adoption by Parliament and Council, so it is not yet law. Check its current status before citing it.
Recycling, recovery and recycled content
These figures are set in Annex XII of the regulation itself. Commission Delegated Regulation (EU) 2025/606, adopted on 21 March 2025 and published on 4 July 2025, fixed the methodology for calculating and verifying them, which removed the last excuse for treating the targets as provisional.
Recycling efficiency, by battery weight
| Deadline | Lead-acid | Lithium-based | Nickel-cadmium | Other |
|---|---|---|---|---|
| 31 December 2025 | 75% | 65% | 80% | 50% |
| 31 December 2030 | 80% | 70% |
Material recovery from waste batteries
| Deadline | Cobalt | Copper | Lead | Nickel | Lithium |
|---|---|---|---|---|---|
| 31 December 2027 | 90% | 90% | 90% | 90% | 50% |
| 31 December 2031 | 95% | 95% | 95% | 95% | 80% |
Minimum recycled content in new batteries
| From | Cobalt | Lead | Lithium | Nickel |
|---|---|---|---|---|
| 18 August 2031 | 16% | 85% | 6% | 6% |
| 18 August 2036 | 26% | 85% | 12% | 15% |
Collection targets sit alongside these: 63 per cent of portable batteries by 31 December 2027 and 73 per cent by 31 December 2030, and for light means of transport batteries 51 per cent by 31 December 2028 and 61 per cent by 31 December 2031. Producers fund the collection systems that have to reach those rates.
The lithium recovery targets are the demanding ones, and the regulation itself allows them to be amended in light of market and technological developments. Lithium recovery has historically been the step recyclers skipped, because pyrometallurgical routes lose lithium to slag and the recovered value did not justify the additional processing. These targets are a large part of why new capacity has been built around hydrometallurgical routes.
Recycled content requirements deserve particular attention, because they create demand for recycled material that is independent of its spot price against virgin material. For lithium iron phosphate, which contains no nickel or cobalt and therefore has weak recycling economics on metal value alone, that regulatory demand is close to the whole business case.
Alongside this, the Commission's March 2025 amendment to the List of Waste classified black mass and certain waste battery fractions as hazardous, which tightens shipment controls including restrictions on export to non-OECD countries. For anyone modelling recycling capacity, that changes where material can physically go.
What to do about it
If you place batteries on the EU market: identify your product categories and the specific delegated acts that gate your obligations, and track their adoption rather than the headline dates. Build the carbon footprint data collection now, since site-specific primary data from upstream suppliers takes far longer to obtain than the calculation takes to perform.
If you are building a product with a service life past 2027: specify the passport data model at design time. State of health, durability parameters and composition data are much cheaper to capture from the start than to retrofit into deployed assets.
If you are procuring: put the compliance obligations into supplier contracts explicitly, including the right to the underlying data rather than only a declaration. A supplier's certificate is not usable evidence if a market surveillance authority asks how a number was derived.
If you are in recycling or second life: the recovery targets and the black mass classification shape both process selection and logistics, and the recycled content requirements are the demand-side mechanism that makes low-value chemistries viable to process at all.
