Why does the dash cam battery not hold a charge?
1 Answers
Dash cam batteries do not hold a charge because the built-in battery of a dash cam is very small, with a capacity of only a few hundred milliamps. When vehicle parking detection is activated using the built-in battery, it typically lasts only about 20 hours. Most modern dash cams come equipped with both a built-in battery and an external power supply interface. The built-in battery is usually a lithium battery, while the external power supply is generally provided through the cigarette lighter. It can be connected to the cigarette lighter, ACC, or directly to the car battery. A dash cam is an instrument that records images, sounds, and other relevant information during vehicle operation. After installation, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents.
