What does the EU Battery Regulation change for buyers?

The EU Battery Regulation puts almost all duties on the seller of a battery, not on the company that buys it. For a buyer, it mostly means paperwork and data you are entitled to ask for. When you buy a business battery, the questions in this article show whether a supplier is ready for 2027 or not.

Perhaps a quote says "compliant with Regulation 2023/1542" or "passport-ready", and you have no idea what that covers. Or your purchasing department asks whether the battery needs a passport, and nobody can answer. One buyer put it this way on a forum: the market "seems to be a bit immature and I'm not even sure the installers really understand their own products".

The hidden cost is time. A business battery stays on your site for ten years or more. If it arrives without its documents, you cannot prove its health, value or safety later. Not to an insurer, not to a buyer and not to a recycler. And if you import a battery yourself from outside the EU, some duties of the seller can land on you.

We see the end of that chain in our own work. In our Battery Disassembly Center we take apart lithium batteries from cars, home batteries and bicycles. Clear dismantling instructions are essential there, and that is exactly the kind of information the battery passport will carry.

What is the EU Battery Regulation, and which batteries in your company fall under it?

The EU Battery Regulation (Regulation (EU) 2023/1542) sets rules for every battery sold or used in the EU, from its design to its recycling. It replaced the old battery directive and applies directly in Belgium, without a national law in between. It covers all chemistries: lithium, lead, nickel and sodium.

The regulation sorts batteries into five categories. The category decides which rules apply, so it is the first thing to know about each battery you buy.

Source: Regulation (EU) 2023/1542, article 3. One detail surprises many buyers: a stationary storage system counts as an industrial battery "regardless of where and by whom" it is used. A home battery is therefore an industrial battery in the eyes of this law.

The second threshold is capacity. Most of the heavy rules, such as the passport, the carbon footprint and the performance data, apply to rechargeable industrial batteries above 2 kWh. Almost every business battery, forklift battery and larger UPS string is above that line.

Which EU Battery Regulation dates matter when you buy a battery?

Four dates matter most for a company that buys batteries: 18 August 2024, 18 August 2025, 18 February 2027 and 18 August 2027. Some later dates depend on rules the European Commission still has to adopt.

Sources: Regulation (EU) 2023/1542, articles 7, 8, 10, 11, 12, 13, 14, 77 and 96; Regulation (EU) 2025/1561 for the due diligence date.

What is a battery passport, and what will you find in it?

A battery passport is an electronic record of one battery, reached through a QR code on the battery. From 18 February 2027, it is required for every new industrial battery above 2 kWh, every LMT battery and every EV battery.

The passport holds data about the battery model and about that specific battery, including how it has been used. Not everyone sees everything. The regulation sets three levels of access.

Source: Regulation (EU) 2023/1542, annex XIII. The Commission still has to specify who exactly counts as a person with a legitimate interest. The law already names repairers, second-life operators and recyclers, and the purchaser for energy trading through an aggregator.

Three rules are useful to know as an owner:

• The seller keeps it up to date. The company that places the battery on the market must keep the passport accurate, complete and up to date.
• A second life means a new passport. A repurposed battery gets a new passport, linked to the original one. How that works for storage built from used batteries is in our article on second-life batteries for a business.
• The passport ends with the battery. Once the battery becomes waste, the producer or its take-back scheme takes over. After recycling, the passport ceases to exist.

For you as a buyer, the passport is a record you can use later: for a warranty claim, a resale, an insurer or the recycler. A battery delivered before 18 February 2027 does not get a passport after the fact. Its data then depends on the documents you received at purchase.

Which labels and documents must a business battery come with today?

Since 18 August 2024, a new business battery must come with a set of documents under the EU Battery Regulation. You do not have to wait for the passport to ask for them.

• CE marking and an EU declaration of conformity. The declaration states that the battery meets the regulation. It must be available in electronic form, and on paper if you ask.
• A performance and durability document. For rechargeable industrial batteries above 2 kWh: capacity and its fade, power and its fade, and internal resistance. Also round-trip efficiency and expected lifetime in cycles and years.
• Safety documentation for a storage system. The maker must show that the system passed safety tests, for example on thermal propagation, fire and gas release. It must also give instructions for a fire or an explosion.
• Instructions and safety information in a language users can easily understand.
• The crossed-out bin symbol since 18 August 2025. Batteries with lead or cadmium above set limits also carry "Pb" or "Cd".

The safety documentation is a product rule. It does not replace the fire service, permit and inspection rules for your site. Those are covered in our article on whether a battery on your business site is safe.

Which battery data are you entitled to as the owner?

Since 18 August 2024, the battery management system of a stationary storage system must hold up-to-date data on its state of health and expected lifetime. The person who legally bought the battery gets read-only access, directly or through a third party acting for them.

The battery management system (BMS) is the electronics that watch over the cells. The regulation lists what it must record for a storage system:

• State of health: remaining capacity and, where possible, remaining power, round-trip efficiency and internal resistance, plus how self-discharge evolves.
• Expected lifetime: dates of manufacture and commissioning, energy throughput and full equivalent cycles. Also harmful events, such as deep discharges or time in extreme temperatures.

The law names three purposes for that access. You can offer the battery to an aggregator or on the energy market. You can judge its residual value and remaining life. And you can prepare it for reuse or a second life. Ask how you get the data before you sign, not when you want to sell or extend the system. What else a good service contract covers is in our article on warranty and maintenance of a business battery.

What does the carbon footprint rule mean for a business battery?

Rechargeable industrial batteries above 2 kWh will need a carbon footprint declaration per battery model and per factory. The figure is expressed in kg CO2 equivalent per kWh the battery delivers over its expected life.

The date is 18 February 2026, or 18 months after the Commission publishes the calculation method and the format, whichever comes later. That method was not on EUR-Lex in September 2026, so the declaration is not yet due for business batteries. After the declaration come performance classes on the label, and later a maximum footprint.

For most companies, the carbon footprint will matter in two places. The first is sustainability reporting on purchased goods. The second is public tenders: public buyers must already weigh the life-cycle impact of batteries. How a municipality or school handles that is in our article on how a public body buys a battery system.

What does battery due diligence ask of your supplier?

Battery due diligence means that the seller checks the social and environmental risks behind cobalt, natural graphite, lithium and nickel in its batteries. It sets up a policy, has it verified by an independent notified body and publishes a report.

The obligation was due on 18 August 2025. In July 2025, the EU postponed it to 18 August 2027 with Regulation (EU) 2025/1561, because the verification bodies and schemes were not ready. The Commission guidelines were moved to 26 July 2026.

The rule only applies to sellers with a net turnover of 40 million euro or more, alone or as a group. Many installers and smaller importers stay below that line. The battery maker behind them may not. Such a seller must publish its report every year and share relevant findings with its direct customers. The public part of the passport will also carry information on responsible sourcing.

For you as a buyer, due diligence is a question for the offer, not a duty. Which chemistry uses which of those raw materials is explained in our article on LFP, NMC or sodium-ion for a business.

Do you take on duties when you import a battery yourself?

Yes, you can. The EU Battery Regulation puts its duties on "economic operators": the manufacturer, the importer, the distributor and the producer. Buying from outside the EU can move one of those roles to your company.

• Manufacturer: also a company that has a battery built and puts it into service for its own purposes.
• Importer: a company established in the EU that places a battery from outside the EU on the EU market.
• Producer: among others, a company established in Belgium that supplies a battery from another country in Belgium for the first time, on a professional basis.

Producers must register in the producer register of every member state where they first make a battery available. They may only sell batteries there once they are registered. In that registration, the producer states how it meets its take-back duties.

What does battery removability change for the tools and e-bikes your company buys?

From 18 February 2027, devices with a portable battery must let the user remove and replace it with ordinary tools. Light vehicles such as e-bikes must allow an independent professional to replace the battery and even single cells.

Spare batteries must stay available for at least five years after the last unit of a model is sold, at a reasonable price. Software may not block a compatible replacement battery. There are exceptions. Examples are devices that need a permanent power supply for safety or data integrity, and appliances that are washed or rinsed.

For a company with a fleet of laptops, scanners, tools or e-bikes, this makes repair cheaper than replacement. It does not apply to a business battery or a forklift: those are industrial batteries with their own rules.

Who takes a business battery back at the end of its life, and who pays?

Since 18 August 2025, producers of industrial batteries must take back waste industrial batteries free of charge. That holds regardless of brand, chemistry or condition, and without an obligation to buy a new battery from them.

Distributors of industrial batteries must also take back waste batteries of the categories they sell, at or near their outlet. One nuance matters for companies: the regulation only rules out dismantling and collection costs for private, non-commercial users. A company can still pay for removal on site, packaging or transport.

What should you ask your battery supplier from now on?

Ask for the documents the EU Battery Regulation already requires, and for a clear plan for the passport. These questions work for a storage system, a forklift battery or a UPS string.
