Slow charge automatic stop is a feature that allows a charger or charging device to automatically stop charging during charging. This feature is designed primarily to protect the battery from overcharging damage.

When the charger or charging device detects that the battery is full, or has reached a preset charging time or capacity, it will automatically stop supplying power to the battery. The goal is to prevent the battery from overcharging, which can cause damage, heat, or even explosion.

The principle of automatic stop of slow charge is based on the charging characteristics of the battery. When the battery starts to charge, the voltage and current are low, but as the charging progresses, the voltage and current will gradually increase. As the battery nears full, the growth of voltage and current slows down until it eventually stops changing. By monitoring the voltage and current changes of the battery, the charger or charging device can determine the charging state of the battery, so as to stop charging at the appropriate time.

In addition to protecting the safety of the battery, the slow charge automatic stop also helps to save energy and extend the life of the battery. Overcharging will not only waste electrical energy, but also may cause damage to the chemical structure of the battery and shorten the life of the battery. By stopping the charge in time, these potential problems can be minimized.

It should be noted that the slow charge automatic stop function does not apply to all types of batteries and charging devices. Different types of batteries and chargers may have different charging characteristics and protection mechanisms. Therefore, when using, you should choose the appropriate charging device according to the actual situation, and follow the relevant instructions and safety recommendations.

In short, slow charge automatic stop is an important function to protect battery safety, save energy and extend battery life, it prevents the risk of overcharging the battery by monitoring the charging state of the battery and stopping charging at the appropriate time.
There are many possible reasons why slow charge automatically stops, here are some of them:
1. The battery is full: Some slow chargers can detect the battery's power level and automatically stop charging when the battery is full to avoid overcharging, because overcharging will damage the battery.
2. Charger overheating: overheating will damage the charger or battery, some slow charging devices have overheating protection function, when the charger is overheated, it will automatically stop charging to protect the battery and charger.
3. Excessive load: If the connected device requires a higher current than the output current of the charger, the charger may automatically stop charging to protect the battery and device.
4. Charger failure: If the slow charger fails, such as internal component damage or line overload, it may automatically stop charging, in which case the charger needs to be replaced.
If the slow charger continues to fail to charge, you can check the status of the battery and charger and whether the connection cable is properly connected. It is recommended to follow the battery and charger instructions or dealer recommendations to learn how to properly use and maintain the slow charger.
