If the driving recorder is turned on 24 hours a day, will it affect the life of the car battery?

If the driving recorder is turned on 24 hours a day, will it affect the life of the car battery? First of all, it depends on whether there is an independent power supply such as lithium battery for continuous power supply. If the driving recorder comes with a lithium battery, it will be charged by a cigarette lighter when using the car. After the car is turned off, the power of the cigarette lighter will be cut off, and the driving recorder can only work on its own battery, which will not affect the car battery.

However, if there is no independent power supply, the demand for battery power supply is relatively high if electricity is obtained from the interface (such as OBD). As long as you don't drive for a day or two, the battery may be too low to start the engine normally. I'm not afraid of jokes. I paid the IQ tax in this respect.

The poor old household I live in has a poor education level and the parking environment is not very peaceful, so I bought a P-brand driving recorder in summer, and powered on it through the OBD interface (the car stopped when it turned off) to monitor the abnormal situation after parking. However, the actual energy consumption of this product is much larger than advertised, and the fuse of OBD interface burned once from the beginning. But I can use it normally by changing the fuse, so I don't take it seriously anymore.

These product introductions cannot be exaggerated, even if they are false propaganda. It took less than a month to use this thing, and the battery problem came. First, the automatic start-stop work is not normal (air conditioning, ramp parking, steering wheel angle is too large, temperature is too high and other routine conditions. Not included), and then the car stopped running because of the power failure. And the first time I felt that the battery was just dead, I made a detour to fully charge the battery. As a result, it still didn't work after the flameout, only to realize that the battery could not be charged at all, and it was only used for one and a half years when it was scrapped.

Here, I would like to remind friends who have difficulty in choosing a driving recorder. All-weather monitoring function is a false concept for most driving recorders, and the parking monitoring I bought without independent power supply is even more rogue. So my suggestion is that the driving recorder should be based on "driving record" instead of "parking monitoring". If you are worried about safety problems such as scratches and broken windows, either buy your own battery model or try something else.
