- UK battery passport
Selling batteries into the UK: what changed in October, and what did not
Northern Ireland now has UK enforcement behind the EU Battery Regulation, and Great Britain has named a digital battery passport on the record. What applies where, and what does not.
- battery passport access rights
Who may read the restricted part of a battery passport: the draft access-rights act is out
The Commission's draft on battery passport access rights grants access point by point of Annex XIII, sets purpose, retention and sharing rules, and gives purchasers access to their battery's own record. What it says and what it leaves open.
- battery passport pricing
What battery passport compliance costs: our pricing, in the open
An annual platform licence of €10,000, an activation fee from €2.50 per passport, and passport custody from €5 per live passport per year. The full model, with worked examples at 10,000 units.
- battery passport test environment
The registry is open and cannot take a battery. So we tested somewhere that could
The EU registry has been live since July and still has no battery format. We ran our platform through the only open test bed instead. Here is what passed, what it means, and what it does not.
- DPP registry qualified seal rejected
A valid seal can still be rejected: the registry's signing-format rules
User Guide v1.02 codifies why technically valid qualified seals fail DPP Registry verification: embedding format and key custody. Here is the pre-flight check.
- battery passport recycled content
Four fields just came off your February 2027 battery passport checklist
Version 2.0 of the Commission's data-point guidance moves the recycled cobalt, lithium, nickel and lead shares to not-to-be-filled as of February 2027. What changed, why, and what it means for your preparation.
- battery regulation 18 august 2026
18 August has passed: what now applies, what slipped, and the date that did not move
On 18 August 2026 the Battery Regulation's labelling date arrived and the Commission missed its own deadline for the access-rights implementing act. What each means for operators, and why 18 February 2027 is unmoved.
- battery passport backup copy
Your own copy of a battery passport is not the back-up the law asks for
ESPR Article 10(4) requires a back-up of every digital product passport held through an independent provider. Keeping your own exports does not satisfy it. Here is what the rule says, why it exists, and what remains unsettled.
- battery passport manufacturer obligations
You make batteries and sell them in the EU: the passport work on your desk
You manufacture in-scope batteries and place them on the EU market yourself. No importer or AR sits between you and Article 77. Here is the actual scope of the work before 18 February 2027.
- battery passport mandatory data points
The Commission has finally said which battery-passport fields are mandatory
On 28 July the Commission published its first per-category matrix of battery-passport data points — mandatory, optional, or not to be filled — as of February 2027. Here is what it settles, and what it does not.
- IR 2026/1778 draft vs adopted
IR 2026/1778 binds from 6 August. Every change from draft to adopted — in full
The registry regulation enters into force on 6 August. We compared every article of the adopted text against the draft — and start by correcting our own 20 July reading.
- battery passport transfer of ownership
Your client leaves. What happens to their battery passports?
An authorised representative losing a client does not transfer anything. The obligation never moved. Here is what actually triggers a transfer under the registry rules — and what the rules still do not say.
- unique product identifier ISO 15459
Your battery passport is only as valid as its identifier
Two regulations require the unique product identifier to follow ISO/IEC 15459. That single clause decides whether a passport is valid at all — and for some companies it means a procurement step nobody has scheduled.
- DPP registry verification
You cannot register a battery passport today. Verify anyway
The DPP registry is live, but battery registration is not yet possible — for anyone. We completed operator verification this week; here is what is actually open, and why it is the half that matters.
- EU DPP registry live
The registry is live. What changed today, and what did not
The EU's DPP registry became operational on 20 July, and the implementing regulation is adopted. What the final text confirms, the one point where it differs from the draft, and the date that still binds you.
- EU DPP registry submission
What registry submission will actually look like
The draft implementing regulation for the EU's DPP registry is the first official description of how passport submission will work. Here is what it specifies, what is still draft, and what it means for operators.
- battery passport importer obligations
You import batteries from a non-EU maker: where you stand on 18 February 2027
From 18 February 2027, every in-scope battery you place on the EU market needs a digital passport — and as the importer, the obligation sits with you. Your position, in plain terms.

- ESPR 2024/1781
The DPP service-provider delegated act slips to Q4 2026
What the delay means for accreditation timing, and why the binding deadline is the 18 February 2027 passport date regardless.
- EU 2023/1542 Annex XIII
Collecting the data for a battery carbon-footprint declaration: the challenges to plan for
A carbon-footprint declaration isn't a number you look up — it's a study built from plant-level primary data, a prescribed methodology, and a verification trail. Here are the data-collection challenges that follow directly from the rules.
- EN 18222 / EN 18223
The DPP standards suite, in plain terms
What the CEN/CENELEC DPP standards actually require of a passport you host — and the honest status of their adoption.
- EU 2023/1542
Where an operator stands: inside and outside the EU
The obligation does not depend on where you are based — only on whether your batteries are placed on the EU market. The two positions, and the one obligation they share.
