New battery but still not working?
A fresh 1 × CR2032 should restore Wahoo TRACKR Speed if the battery was the problem. Work through the checks below before replacing the device.
- Check orientation
Confirm the cell is seated correctly: Positive (+) side facing you
- Check the contacts
Wahoo does not recommend bitter/child-deterrent coated CR2032 cells (e.g. some Duracell) — may reduce performance.
- Check the battery type
This device needs 1 × CR2032 (lithium). Rechargeable cells are not supported for this device. Same size does not always mean the same battery.
- Confirm the battery itself
For most coin cells, fitting a known-good fresh cell of the correct code is simpler than capacity testing.
- Still not responding?
If a correct, fresh battery installed properly does not restore the device, the fault may be elsewhere — the device may need service or replacement.
