What Is the Best Battery-Operated Dash Cam?

A battery-operated dash cam is a great way to protect your car 24/7. When your camera senses the vibrations from an impact, it will turn on and record a short loop. That loop can help you prove liability in an accident and help track down responsible parties. 

In this article, we’ll look at the five best battery-operated dash cams. Unlike other batteries that require the car to be on to function, these cameras have internal power storage and can be connected to an external power supply. Here are the best models on the market today.

Why Use a Battery-Operated Dash Cam?

While most dash cams work off the car’s power system, there are a number of reasons you might prefer to rely on an external battery. Whether you’re trying to preserve your car’s gas mileage or need to record while you’re parked, a battery-operated dash cam may be the right answer for you. 

How Does a Battery-Operated Dash Cam Work?

The best battery-operated dash cams work with two different power sources. The main power is from an external battery pack that you can install in your car. The second is a backup power system, either a lithium-ion battery or a supercapacitor. This backup battery can record between three to five minutes of video, usually triggered by a collision. 

What to Look for with Battery-Operated Dash Cams

 When it comes to choosing the best battery-operated dash cams for your needs, there are several factors to consider, including:

Easy Setup

The less time it takes to install your dash cam, the better. Some models make it easy to move your camera from one vehicle to another, as well. 

Record Time

Battery-operated dash cams usually record short loops, between 1 to 10 minutes long. However, some models record more, while others allow you to set your preferred recording length. 

Video Resolution & Quality

The higher the video resolution is, the more likely you’ll be able to use the recording from your dash cam, whether you’re fighting the insurance company or trying to track down a hit-and-run driver. 

Warranty

While no one buys a dash cam expecting it to break, there’s always the potential that something might happen. You should make sure to choose a dash cam from a manufacturer that backs their product up with a warranty. 

Memory (SD Card)

Your battery-operated dash cam uses an external memory device to store its recordings. This makes it easy to transfer them from device to device. Make sure you get a MicroSD card that’s big enough to hold the recordings you think you might need. 

Battery Capacity

While no dash cam runs primarily off its own internal battery, it’s a good idea to choose a model that can provide emergency power or one that can record even when your car is parked and not connected to an external battery.

FAQ

Are There Dash Cams that Use Batteries?

While most dash cams have either a lithium-ion battery or supercapacitor as a backup power supply, they rely on an external power source. However, you can connect these battery-operated dash cams to either the car’s power supply or to an external battery.

How Long Do Dash Cam Batteries Last?

Internal dash cam batteries are only expected to last for about 3 to 5 minutes. However, that should be enough time to record the important information in the case of a collision while your car is parked.
