The QR code on the battery.
The code is the way into the passport. It must stay readable and permanently lead to the right destination.
What the regulation requires
Every battery with a passport obligation needs a unique identifier and a QR code giving access to the passport. The code must be clearly visible, legible and durable. If that isn’t possible on the battery, the regulation provides exceptions, for example for packaging.
The address behind the code
Once printed, the code can’t be changed. So choose an address you control long-term, ideally on your own domain or your provider’s. A change must not leave printed codes pointing nowhere.
GS1 Digital Link is a widely used standard for such addresses. Check with your customers whether they expect it.
Tips for label and printing
- Test with several phones before series production, including in poor light
- Check the minimum size on the finished label, not on screen
- Choose high contrast, dark on light
- Choose material to suit the environment: heat, oil, abrasion
- Keep the quiet zone around the code clear
