The headline date is 18 February 2027 — when the battery passport becomes mandatory. But the EU Battery Regulation phases obligations in over several years. Here is the practical timeline.
| Date | What happens |
|---|---|
| 18 Aug 2023 | Regulation (EU) 2023/1542 enters into force. |
| 18 Feb 2024 | First obligations begin to apply. |
| 18 Feb 2027 | Battery passport mandatory for LMT, industrial (>2 kWh) and EV batteries. |
| 2028 onward | Further reporting and recycled-content obligations phase in. |
| From 2030/2031 | Mandatory recycled-content thresholds tighten. |
The 18 February 2027 obligation applies to batteries placed on the market after that date — including units made earlier. Plan your data collection well ahead of the date, not on it.
