How Long Does a Dash Cam Battery Last?
2 Answers
The battery in a dash cam typically lasts one to two years. The battery in a dash cam serves as a backup power source, as the dash cam is primarily powered by the car. If the car's power is turned off, the dash cam will automatically shut down within a few minutes. The functions of a dash cam include: 1. Protecting the driver's legal rights by providing valid evidence; 2. Playing back recorded footage to clarify accident liability; 3. Reducing hit-and-run cases; 4. Providing evidence for insurance claims in court during road accident cases; 5. Offering decisive evidence for solving cases involving professional scammers or roadside robberies.
The battery life of a dash cam mainly depends on the usage scenario and battery type. My car came with a dash cam, and after over two years of use, the parking monitoring mode can last about an hour and a half. However, in the summer heat, when the car interior temperature soars, the battery life may shrink to around half an hour because the battery deteriorates quickly in high temperatures. It performs slightly better in winter, but the power output is halved. The dash cam usually charges via the cigarette lighter plug, automatically charging while driving, and it typically takes about half an hour to fully charge. I've encountered battery swelling issues before and had to replace it promptly to avoid missing accident footage. I recommend choosing a model with a supercapacitor for better durability—it lasts for years without breaking down, is less affected by temperature, and setting a low-power mode can extend usage. Regularly check the battery's health status—safety first.
