Ways to Prevent Your Dash Cam Draining Your Car Battery
It is a hassle if your car battery runs out of energy. You can’t get your car started and bring it to a shop to fix and recharge the battery. But there are ways that you can do to prevent this from happening and still use your dash camera.
- Hardwire kits
A hardwire kit serves as a "piggy bank" of energy for your dash camera. It connects to the fuse box so that the dash camera will have its supply of energy. And even if the car is switch off, it will not use the 12v of energy directly from the cigarette socket. But instead, it uses the energy stored in the kit. Some hardware kits also have an option to set a "Permanent Live" or "Switched Live" supply to save the battery life of the car. The "Permanent Live" sets a limit up to what voltage the dash camera can use. It is to prevent the car battery from being fully drained. While the "Switched Live," the das camera will switch on whenever the engine starts.
- Proper hardwiring
Hardwiring connects the dash camera to the battery. It requires you to set up your dash camera and connect it to the car battery. But the hardwire kit saves some energy to avoid your car battery from draining. Also, the cigarette lighter socket will be open for other usages aside instead of using it as a power source for the dash camera. This ensures that the wires' installation is correct and that you will not have to worry about battery drainage.
- Disable the “Parking Mode”
If your dash camera or hardwire has a “Parking Mode,” disable it. When your dash camera is still running while your car is parked, it can drain energy from your car battery. Some dash cameras have at least 5-15 seconds delay before it switches off. This is to maximize the amount of energy left in its cable.
- Use a capacitor or battery
Both the capacitor and battery for your dash camera can help your car battery from draining. These two are like power banks to your dash camera and does not get any power source from the car battery. But the downside of these two is that it will not last long. You will have to recharge them regularly so that it can provide the right amount of energy that your dash camera needs. And having a back-up can help you keep your dash camera running.
When to Change Car Batteries
There are ways for you to identify that your car battery is weak. And when the battery is weak, it is time to recharge them. But there are times when you need to replace the battery because it can no longer give your car the right amount of energy it needs to start. Here are some signs that tell your car battery is weak.

If you decide to have a dash camera in your car, be sure to have a power source that can help prevent the draining of your car battery.
