BQ27Z561: Explain the SOH execution conditions and change process

Hi Ti team,

1. The conditional process of BQ27Z561_SOH decreasing from 100% to 99% and 98%~~.
2. Which participation of electricity meters has an impact on SOH? For example, charge and discharge current, charge and discharge cycle, temperature, capacity, internal resistance, etc., and indicate which condition has the greatest impact on SOH?
3. What is the recommended SOH reduction before replacing the battery?
4. If the battery is severely depleted, what information can the power meter use to determine?
5. Are there any application guidelines related to SOH.

Thanks!
