Misconception of battery self-discharge

Self-Discharging After Charging Some friends say that the battery voltage drops rapidly after charging, indicating that self-discharging is too fast. The reason is that the charging voltage is higher than the actual battery voltage due to the polarization of the battery during charging.

Voltage Drop Process After Charging-This is the battery voltage process from the charging voltage to your own voltage. The actual battery voltage that is the result of the charging voltage is called overcharging, rather than the so-called “virtual power”, and in electrochemical terms there is no name for virtual power. Therefore, the voltage drop after charging is mainly the loss of overvoltage, the rate of self-discharge between them is very small and can be ignored. In addition, it takes more than 4 hours for the voltage to stabilize substantially after charging, and when charging is completed with a constant current or constant voltage, the difference in pause time is not so large.
