What is the battery configuration? I think the gauge has a minimum voltage it needs to have on the BAT pin before it shuts down.

Hello，

For this special battery cell with a nominal voltage of 2.34V, the CHEM ID error is too large (please refer to the attached data for details). How should this be handled? Does this IC support the CHME ID of this type of battery cell

You can send us these batteries, so we can create a CHEMID for them. Please refer to this thread on how to do so:
