Millet intelligent charging charger will automatically cut off the charging function after charging to a certain amount of electricity to avoid overcharging to the battery damage. However, even if the charger is powered off, the battery may continue to receive a small current, causing the charge display to remain stuck at 100%.
This is due to small errors between the battery capacity and the charge control system, as well as the battery's own discharge characteristics after the charge is finished. Therefore, even if it shows charging to 100%, in fact the battery may not be fully charged. It is recommended that users pay attention to avoid overcharging and discharging during use to extend battery life.
