Does a 2011 HHR Have a Battery & Where Is It in the Car?


Like all modern vehicles with an internal combustion engine, your 2011 Chevrolet HHR requires a large, high-amperage battery, which is primarily intended to engage the engine's starter motor and provide constant power to the on-board computer systems, while allowing other electronic accessories to operate when the engine isn't running. Although it's typical for most passenger vehicles to house the battery under the hood, the battery for your HHR is located at the tail end.
