- Check known model-specific issues
Solar-assisted model: replace the listed coin cell as needed; solar reduces drain in bright light.
- 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.
