Tell us what the battery is doing and our service team will contact you. You will need the serial number printed on the pack.

1 How to reach you
2 Which battery

The category, model and serial number are printed on a label on the pack itself.

3 What is wrong

Tell us what the battery is actually doing — not charging, losing range, an error on the display, a smell or a noise. The more specific you are, the better prepared the engineer arrives.

4 Where the battery is
5 Invoice optional

Only if you have it to hand. It helps us confirm the warranty faster, but a service request is raised either way. JPG, PNG, WEBP or PDF, up to 5 MB.
