Abnormal capacity data

Why is the impact of stopping the test on battery capacity less than the impact

Latest updated: Mar 27, 2024
  • Issue description: In testing devices of the same model, the impact on capacity after a 9-hour stoppage is less than 1%, while the impact on capacity after a power outage followed by restoration is as high as 4%.

  • The device being powered off and restarted does not affect its accuracy, and therefore does not impact the capacity. However, if there is a prolonged power outage or if the power is cut during a charging or discharging step, the voltage of the battery will fluctuate. Consequently, when power is restored, it will certainly have an impact on the capacity.

  • To verify this, the same amount of time can be used to stop and then restart the device without cutting the power.
