Cigarette Lighter to OBD2 Battery Saver Cord: Everything You Need to Know

A cigarette lighter to OBD2 battery saver cord is a handy tool that connects to your car’s OBD2 port and provides power from the cigarette lighter socket, allowing you to work on your vehicle’s electrical systems without draining the battery. This is particularly useful when installing car alarms, radios, or other electronic accessories.

Understanding the Need for a Cigarette Lighter to OBD2 Battery Saver Cord

When working on your car’s electrical system, disconnecting the battery is often necessary to prevent shorts or damage. However, this can lead to the loss of stored settings in the car’s computer, such as radio presets and clock settings. A cigarette lighter to OBD2 battery saver cord prevents this inconvenience by providing continuous power to the vehicle’s electrical system while the main battery is disconnected. This simple device can save you time and frustration.

How Does a Cigarette Lighter to OBD2 Battery Saver Cord Work?

The cord works by drawing power from the cigarette lighter socket, which is typically always live, even with the ignition off. This power is then fed through the cord and into the OBD2 port, maintaining power to the vehicle’s computer and memory. It’s a simple yet effective solution to a common problem.
