Hello

My customer is using Battery pack using SN8765 ( Base device is bq3050 ) already in the market.

But they want to investigate SN8765 ( bq3050) themselves .

Anyway,

What procedure is the necessary to remove Battery pack from system ?

They want to remove Battery in the shipping .

So they want to know the software procedure of MCU in the system.

Customer should just follow " 5.2.1 BATTERY PACK REMOVED Mode/System Present Detection"?

The SN8765 also has the PRES pin and it should turn the CHG and DSG FETs off when the pack is removed, if this feature was used in the system. I assume that you are just referring to removing the battery pack from the system and not removing the cells from the gauge.
