What Is the Difference Between Battery Pack EOL Testing and Aging Testing?

Oct 16, 2026

EOL Testing: Checks whether a completed battery pack meets defined electrical and functional acceptance criteria before leaving the production line.


Aging Testing: Runs programmed charging, discharging, rest and cycling steps while recording data such as voltage, current and capacity to evaluate pack performance over the test period.


The two processes serve different quality checks and complement each other. Test items, operating parameters and equipment configurations should be selected according to your pack specifications and quality requirements.
