If you are shopping for a home battery in 2026, you will not see a passport yet. The first mandatory battery passports arrive on 18 February 2027, and they apply to specific categories — not to the small 5–15 kWh units most households install. But the regulation behind the passport, the EU Batteries Regulation (EU) 2023/1542, is already shaping what manufacturers must disclose, and it will change the information you see on labels and in product documentation before the passport itself appears.
This guide explains what the passport is, which batteries it covers, and what you should check when buying storage in 2026 — without inventing fees, subsidies, or deadlines that are not in the regulation.
The battery passport is a digital record that must accompany certain batteries placed on the EU market. It is not a paper document or a sticker — it is an electronic record, accessible via a QR code or data carrier on the battery, that links to a set of information about that specific battery unit.
Under the Batteries Regulation, the passport must include:
The passport is part of a broader push for transparency and circularity. It is meant to help recyclers, regulators, and consumers understand what is inside a battery and how it can be reused or recycled.
The regulation defines several battery categories. The passport is required for:
Most home/stationary storage systems are classified as industrial batteries. If your home battery has a capacity above 2 kWh — which virtually all do — it is in scope for the passport. That means your battery will need a passport when the requirement kicks in.
The Batteries Regulation entered into force on 17 August 2023, replacing the 2006 Batteries Directive. However, the passport requirement is phased in. The first passports become mandatory on 18 February 2027 for LMT batteries, industrial batteries above 2 kWh, and EV batteries.
As of 2026, no battery passport is yet required. But manufacturers are already preparing: they must collect and verify data, set up digital systems, and ensure compliance. For you as a buyer, this means that in 2026 you may start seeing more detailed environmental and performance information on battery labels, even before the passport is mandatory.
In 2026, the passport is not yet a legal requirement. However, the regulation has already introduced other obligations that affect what you see and what you can expect:
What does not change in 2026: there is no mandatory passport, no central database you can check, and no requirement for your installer to provide one. If a supplier offers a ‘battery passport’ in 2026, it is likely a voluntary initiative or a marketing term — not the EU-mandated passport.
Even though the passport is not yet mandatory, you can future-proof your purchase by asking the right questions:
Remember, the passport is about the specific battery unit, not the brand or model. So keep your purchase documents and any QR code you receive — they will be useful when the passport system goes live.
| Battery type | Passport required? | Timing (as of 2026) |
|---|---|---|
| Home/stationary storage (industrial, >2 kWh) | Yes | From 18 February 2027 |
| Home/stationary storage (industrial, ≤2 kWh) | No | Not in scope |
| LMT (e-bike, e-scooter) | Yes | From 18 February 2027 |
| Electric vehicle (EV) | Yes | From 18 February 2027 |
| Portable (e.g., AA, phone batteries) | No | Not in scope |
Because the passport is not yet live, you need to rely on other information. Here is a practical checklist:
Be aware that the regulation’s requirements may be implemented differently by each manufacturer. Some may provide more information voluntarily, while others may only meet the minimum. Always ask for written documentation.
From 18 February 2027, any new battery in scope must have a passport before it can be placed on the market. That means when you buy a home battery after that date, you should receive a QR code that gives you access to the passport. The passport will be accessible to you as the consumer, and you will be able to see the battery’s carbon footprint, materials, and performance data.
There are also plans for a central EU database, but as of 2026, the exact access mechanism is not fully defined. The regulation states that the passport must be accessible to consumers, but the technical details are still being developed.
