Can you tell me the battery group size for a 2010 Chevrolet HHR?

The 2010 Chevy HHR comes equipped with a size 90 (T5) battery that measures 9.50 inches in length X 6.90 inches in width X 6.90 inches in height and weighs just over 30 pounds. It features top post terminals, with the positive terminal located on the right side. The HHR’s battery is situated in the rear cargo area alongside the spare tire. To access it, you need to open the liftgate, lift up the carpet and floor panel to reveal the spare tire and battery. When replacing the battery, it is important to disconnect the negative terminal first, as this unlinks the battery from the car's frame. If the positive terminal is disconnected first and accidentally comes into contact with something metal on the car, it may lead to a short circuit in the electrical system.
