The charging reverse switch light is usually caused by the charger input voltage and the battery's positive and negative terminals. Under normal circumstances, the output current of the charger is DC current, and the battery also needs DC current to charge. In this process, if the voltage input by the charger is inversely connected to the positive and negative terminals of the battery, it will cause the charge to be inversely connected, resulting in the charge inversely connected light.
If the charging reverse switch light is on, it is recommended to stop charging immediately and check whether the charger is connected correctly. If it is because the charger input voltage is connected to the positive and negative terminals of the battery, the battery and the charger should be reconnected to ensure that the connection is correct before charging. If the charging reverse lamp is still on, the charger or battery may be faulty. You are advised to replace the charger or battery.
It should be noted that during the charging process, we must follow the correct charging method and precautions to ensure that the charger and battery are connected correctly to avoid safety accidents. At the same time, it is also necessary to use high-quality chargers and batteries to ensure the safety and stability of the charging process.
The charge backlight is usually due to one of the following reasons:
1. Battery short circuit: The battery may be subjected to external pressure, resulting in its internal short circuit, so that the reverse switch light on.
2. Circuit board damage: The circuit board may be damaged, resulting in unstable current, which makes the reverse switch light on.
3. Low battery power: If the battery power is low, it may make the reverse switch light on, prompting the user to charge.
4. There is a problem with the charging cable: the charging cable may be damaged, resulting in unstable current, which makes the reverse switch light on.
5. Battery polarity reversal: battery polarity reversal may also cause the reverse switch light to turn on.
In short, there are many reasons for the charging reverse light, which may be a problem with the battery, or a problem with the charging line, or even other reasons. It is recommended that users check and resolve these problems as soon as possible to avoid affecting the use.
The charger reverse connection indicator usually means that when the charger plug is inserted into the power socket, the internal circuit of the charger is incorrectly connected due to the reverse plug or socket connection and other reasons, and can not work normally, the indicator light will light up to remind the user to reverse the plug or socket direction and reinsert.
The reason is that the converter of the charger is damaged, can not be converted and charged, replace the charger resistor. Battery welding, check with a multimeter.
Charger insurance burned out, replace the charger. If the power cable is disconnected or in poor contact with the battery socket, replace it.
Please confirm again whether the wiring is correct. If you want to confirm that there is no reverse connection, there is a problem with the reverse connection indicator circuit. Remember to reverse the polarity of the charge, there may be a safety accident.
