New battery but still not working?
A fresh 1 × SR920W should restore Orient RA-KB0001S if the battery was the problem. Work through the checks below before replacing the device.
- Check the battery type
This device needs 1 × SR920W (silver_oxide). Same size does not always mean the same battery.
- Check known model-specific issues
Battery is for calibre VX3WE. Confirm movement marking before ordering.
- 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.
