Test pass yield

Latest updated: Sep 24, 2024

The percentage of the number of qualified tested cells in relation to the total number of produced cells.

Note: Qualified tested cell count refers to cells that, after formation, meet the battery parameter requirements for capacity, voltage, internal resistance, and self-discharge.
