Where is the Battery Located on a Chevy Cobalt
If you have a Chevy Cobalt and can not find the battery, it is located in the trunk next to the spare tire.

To access it, open the trunk, remove the carpet, and locate the battery at the rear of the car.

Why is the Chevy Cobalt Battery Located in The Trunk?

The usual reason for placing the battery in the trunk is to improve the weight distribution and handling of the car.

Since all the weight in a car is in the front, it can make sense to place some of the weight on the rear of the vehicle.

Temperature is also a reason since batteries fail quicker when next to a hot source such as the engine.
