New battery but still not working?

A fresh 1 × CR123A should restore Ring Alarm Panic Button (1st Gen) if the battery was the problem. Work through the checks below before replacing the device.

  1. Check orientation

    Confirm the cell is seated correctly: Match +/- symbols

  2. Check the battery type

    This device needs 1 × CR123A (lithium). Rechargeable cells are not supported for this device. Same size does not always mean the same battery.

  3. Check known model-specific issues

    Generation: 1st Gen uses 1× CR123A — not the same as 2nd Gen 2× CR2032A.

  4. Confirm the battery itself

    For most coin cells, fitting a known-good fresh cell of the correct code is simpler than capacity testing.

  5. 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.

These checks follow this device’s orientation, battery type, and important notes from the maker.
