1. Check whether the charging cable is damaged. You can try to use another charging cable or a charging cable connected to another device to charge. If it can charge normally, it means that there is a problem with your charging cable and you need to replace the charging cable. Check whether the batteryThere's a problem. If none of the above methods can be charged, there may be a problem with the battery itself. You are advised to remove the battery and use a multimeter to check whether the battery voltage is normal.
2, first confirm the use of the charger is working properly, if the charger has a problem, you need to replace the charger. Secondly, check whether the charging cable is damaged. If there is a problem with the charging cable, replace the charging cable. Then check whether there is a problem with the battery. If there is a problem with the battery itself, remove the battery and use a multimeter to check whether the battery voltage is normal. Finally check whether there is a problem with the charging port, you need to replace the charging port.
3. BatteryWhen the lithium electric Angle mill is used, you need to plug in the battery to use, if the battery has been damaged, then even if it is plugged in, it can not power the circuit board, resulting in no power for the circuit board. In this case, we need to replace the battery in order to use the Angle grinder normally. Another possible reason why the lithium electric Angle mill has no power after plugging in the battery is that the circuit board is damaged.
4, in order to solve the above problems, you can try the following solutions: 2) Replace the battery: If the battery is aging, it is recommended to replace the new battery to ensure the charging effect. 3) Replace the charger: If the charger fails, it is recommended to replace it with a new charger2, the charger only shows the red light shining, the green light is not bright, which usually means that the charger is in the process of charging, the battery power is low. During charging, the charger usually shows a red light, and when the battery is fully charged, the charger will show a green light. Therefore, you don't need to worry about the charger or the battery having problems, just wait a while until the battery is fully charged.
3. Check whether the charging cable is damaged. You can try to use another charging cable or a charging cable connected to another device to charge. If it can charge normally, it means that there is a problem with your charging cable and you need to replace the charging cable. Check the battery for problems. If none of the above methods can be charged, there may be a problem with the battery itself. You are advised to remove the battery and use a multimeter to check whether the battery voltage is normal.
1, may be the following reasons: 1. Battery aging: If the battery is used for a long time, it may age, causing the battery capacity to decrease and cannot be fully charged. 2. Charger failure: If the charger fails, it may cause noneNormal charging, need to replace the charger. 3. Charging circuit fault: If the charging circuit is faulty, it may cause failure to charge. You need to check whether the charging circuit is normal.
2, first confirm the use of the charger is working properly, if the charger has a problem, you need to replace the charger. Secondly, check whether the charging cable is damaged. If there is a problem with the charging cable, replace the charging cable. Then check whether there is a problem with the battery. If there is a problem with the battery itself, remove the battery and use a multimeter to check whether the battery voltage is normal. Finally check whether there is a problem with the charging port, you need to replace the charging port.
3. Check whether the battery is faulty. If none of the above methods can be charged, there may be a problem with the battery itself. You are advised to remove the battery and use a multimeter to check whether the battery voltage is normal. If the voltage is too low or unstable, there is a problem with the battery and the battery needs to be replaced. Check the charging port for problems. If the above methods are still unable to charge, there may be a problem with the charging port.
