3.7 When the battery goes from a red light to a red light, it is usually a sign of a low battery. The red light flashing means the battery is very low and needs to be charged in time. If not charged for a long time, the battery may be completely exhausted and rendered unusable.
Also, if the battery contact is bad, the red light will also flash. It is recommended to check whether the contact between the battery and the device is good. If it is loose or dirty, the battery should be cleaned or replaced in time.
If none of the above methods solve the problem, there may be a problem with the battery itself and you will need to replace it with a new one. It should be noted that it is very important to choose a suitable battery model for the device, otherwise it may damage the device or cause safety issues.
In short, if the battery continues toshow red light and flash, we should first consider the low battery power problem and charge or replace the battery in time. If none of these methods resolve the problem, it may be necessary to take the device to a professional repair shop for servicing.
