How Long Does a Dash Cam Battery Last?

[DeAdam]

Generally, the battery of a dash cam can last for one to two years without issues. Here is some relevant information: 1. Backup Power Source: The battery inside the dash cam serves as a backup power source. The dash cam primarily relies on the car's power supply. Typically, if the car's power is turned off, the dash cam will automatically shut down within a few minutes. 2. Battery Types: Dash cams usually come with two types of built-in batteries: lithium-ion batteries and lithium-polymer batteries. When exposed to high temperatures, both types can experience internal short circuits, separator melting, and chemical volatilization, making them flammable and explosive, which may lead to property damage for the user.
