Keeping your batteries compliant

The EU launched its New Batteries Regulation in 2023 to help ensure that future batteries have a low carbon footprint, use minimal substances and require fewer raw materials from non-EU countries. Following a rise in light means of transport (LMT) batteries, particularly in EVs, it’s unsurprising that the EU decided to act. The regulation is all-encompassing, covering everything from raw material sourcing to safe disposal.

We’ve already seen restrictions on hazardous substances like mercury and cadmium come into force, along with a requirement for CE-marking and conformity assessments, found in previous directives. Further changes are now required, with most of these impacting LMT, electric vehicle (EV) and large industrial batteries rated 2 kWh and above.

Labelling and marking

Since 18 August 2024, all batteries, regardless of size and rating, must display a CE mark confirming conformity with EU safety, environmental and performance standards. From 18 August 2026, they will also need to display a comprehensive label, including information such as the place of manufacture, the battery category, weight and information on any hazardous substances, other than mercury, cadmium and lead, that have been used during manufacturing.

While it’s positive that the EU has clarified the required labelling contents, it could present some design and production issues. If manufacturers are now required to list information as extensive as extinguishing agents, the label size will inevitably need to increase, even if the product stays the same. For example, many of our products come in a standard size, so we will need to rethink how we can present this information while complying with the updated guidance.

QR codes

For devices using LMT and large industrial batteries (> 2 kWh), another regulatory change is coming on 18 February 2027. From this date, all LMT, EV and large industrial batteries must include a QR code that provides access to a digital Battery Passport. The QR code must provide publicly accessible data, including all label data, the declaration of conformity and the manufacturer’s identity.

What we do know is that the QR code must be visible, high-contrast and indelible, either printed or engraved on the battery itself — or, if size prohibits, on the packaging or documentation. However, this comes with a caveat. The current guidance is still vague on how the new QR requirements will be implemented. For example, detailed information will be required around digital passports, including what will be publicly accessible, accessible only to notified bodies, market surveillance bodies and the commission; and accessible to people with legitimate interests. Across the various categories, 28 pieces of information will be required, but the Directive is vague on how and where this information will be stored.

While the rules are still hazy, device manufacturers can get ahead by working with a specialist battery expert that is also preparing for the upcoming regulatory changes. At Accutronics, we’ve spent years developing both custom and off-the-shelf products for a wide range of markets, including medical, subsea and defence. We’re aware of the upcoming changes and have been working closely with our customers to assure them during this time of transition.

The next few months will bring some significant changes to how we label and present batteries - but there’s still time to prepare. By working with an experienced battery partner, device manufacturers can keep their production on track and adapt their processes ahead of time.
