Why Does the HHR Have Two Batteries?

by Phil Borges // in Car

If you own a Chevy HHR, you may have noticed that your car has not one, but two batteries. This setup is unique to the HHR model, and it may leave you wondering why it needs two batteries in the first place. In this article, we’ll dive into the reasons behind this design and answer some common questions related to HHR batteries.

What Kind of Battery Does a Chevy HHR Take?

Before we get into why the HHR has two batteries, let’s first discuss the type of battery it takes. Most HHR models use a standard 12-volt battery, just like any other car. However, the second battery in the HHR is a smaller, auxiliary battery that is used for specific functions in the car.

Where is the Battery in an HHR?

The primary battery in an HHR is located in the engine bay, just like in most other cars. You can find it on the passenger side, near the front of the car. It’s housed in a plastic case that’s held in place by a metal bracket. The auxiliary battery, on the other hand, is located in the back of the car, near the spare tire.

Where is the Battery in a 2011 Chevy HHR?

If you have a 2011 Chevy HHR, you’ll find the primary battery in the same location as in other model years – in the engine bay on the passenger side. The auxiliary battery, however, may be located in a slightly different spot depending on the specific model you have. It’s still typically found in the back of the car, though.

How Do You Jumpstart an HHR?

If you ever find yourself with a dead battery in your HHR, you’ll need to jumpstart it to get it going again. Here are the steps to follow:

  1. Locate the primary battery in the engine bay and the auxiliary battery in the back of the car.
  2. Connect the positive (red) jumper cable to the positive terminal on the primary battery.
  3. Connect the other end of the positive cable to the positive terminal on the auxiliary battery.
  4. Connect the negative (black) jumper cable to the negative terminal on the primary battery.
  5. Connect the other end of the negative cable to a metal part of the car’s frame, away from the battery.
  6. Start the working car and let it run for a few minutes.
  7. Attempt to start your HHR – it should start up with the help of the other car’s battery.

In conclusion, the HHR has two batteries because of its unique electrical system that requires an auxiliary battery to power certain functions in the car. While it may be an unusual setup, it’s not difficult to understand or maintain. By following the steps above, you’ll be able to jumpstart your HHR if necessary and keep both batteries in good working order.
