The XTAR VX4 continued to discharge and charge the protected XTAR 16340 cell.

I suspect that the protection circuit of the cell may have Over Voltage Protection (OVP) where it temporarily cuts out at around 4.21V. The XTAR VX4 stops charging the cell. OVP of the cell resets. The XTAR VX4 detects the cell as a newly inserted cell and then it repeats Grade mode.
