Health reset not supported on this chip. You need to edit FCC manually to the value of Measured Capacity after running full Calibration Cycle.

After updating FCC value Health will be updated as well. 

SoH = (FCC / DC) * 100 %

Sorry, me not YT blogger and dont have any equipment to do this. 

 Tutorial on the forum perfectly explains how to do it. One just need to follow it and thats it. 

Hi. You can't change full charge capacity of bq30420 properly, because it need to be changed in other places of dataflash (Cell Rep Cell 0,1,2,3 FCC), not only in one place. I think nlba tool doesn't support it fully. You need native software for bq30420. With it You can change and set whatever You want. Wear level/battery health is calculated as full charge capacity (FCC) moves away from design capacity (DC). For example: for new battery FCC = 4400 mAh, DC = 4400 mAh, then battery health is 100 %, for used battery: FCC = 2200 mAh, DC = 4400 mAh, then battery health is 50 %, FCC = 1000 mAh, DC = 4400 mAh, battery health is about 23 %.

Here you can find a tutorial on how to edit the FCC in the eeprom file: https://www.laptopu.ro/community/how-to-reset-and-repair-laptop-battery-tutorial/fcc-65514mah-on-dell-j1knd-chip-sn8030/

If you have Ev2300/EV2400 you can edit the FCC using bqEVSW software after unsealing the device with NLBA1.

@azzido for using ev2300 or ev2400we need any other paid software? Just for Chang FCC and Health?

We need any other paid software for using ev2300 and ev2400 for health and FCC purpose
