Part Number: BQ34Z100-G1


Hi, I'm using BQ34Z100-G1 with Battery ICR18650-26F spec:

1. Nominal voltage : 3.7V

2. 1-cell

3. cell capacity : 2600mAh

But, it doesn't update the learning status to 5 after charging.

Thank you for your help.

    Hi K L,

    For the device to change to a learned status of 5 after charging, the Qmax must update. After reviewing your log, there appears to be two partial charge events and no discharge events.

    To update the learned status, pleasure ensure that you fully charge the battery, then perform a full discharge at a C/10 rate.

    For more details on performing the optimization cycle, please refer to www.ti.com/.../slua334b.pdf

    Sincerely,
