Save battery parameters

Dear TI

I’m using the BQ27441EVM-G1A with the EV2300 and the Battery Management Studio 1.3.40.

I connected a Li-based battery, I was fine, I mean, measure the voltage is perfect.

But I cannot update some battery parameters, i.e. Design Capacity. Let me present all the followed steps.

1. I click the command SET_CFGUPDATE.
2. I rewrite the Design Capacity.
3. I click Write_All.
4. I click again the command SET_CFGUPDATE.
5. I Disconnect the Battery.

After that, the Design Capacity parameter returns to their original value. How can I make those changes permanent?

Thank you in advance.
