How to change PT Cruiser battery?

The Chrysler PT Cruiser is a great car, but if the battery dies and other troubleshooting techniques don’t work, it only leaves you with one option, and that is to replace it with a new battery. Luckily, replacing the battery in this vehicle model is easy and straightforward.

Safety always comes first so before you begin, make sure that you are wearing protective gear such as gloves and safety goggles. Also, make sure that the vehicle is turned off and parked on a flat, secure surface. Be sure that flammable materials are away from the work area as the battery may produce gas while it is being changed. As soon as these safety measures are all set, you may now proceed to the next steps.

Step 1: find the Chrysler PT cruiser battery location. The battery in a Chrysler PT Cruiser is located under the hood on the driver’s side of the engine. Open the hood and take the prop rod to secure the hood.

Step 2: Remove the air cleaner housing. First, use a nut driver to loosen the inlet tube hose clamp, then detach the tube from the filter housing. Second, you’ll have to disconnect the breather hose that you can find on the side of the filter housing, unlatch its retaining clips and then remove the housing cover. Third, take out the filter and remove the main housing from the retaining grommets that keep this housing in place.

Step 3: Disconnect the battery terminals. Use a wrench to loosen the negative terminal clamp and remove the negative cable for the battery post. Keep this negative cable away from the battery as much as possible to prevent accidental contact. Some would insulate the negative cable to prevent electric shock. Perform the same procedure in removing the positive battery cable terminal.

Step 4: Remove the battery bracket. Use a wrench to loosen the bolt of the hold-down clamp of the battery and remove it. Some batteries may have a protective cover, so if this one is present, you need to remove this as well.

Step 5: Remove the battery from the battery tray. Use both of your hands to lift up the battery out of the tray. Be careful when transporting the battery as it’s heavy, and don’t drop it.

Step 6: Check if the cable terminals and battery tray are clean. If there is corrosion or grime on the terminals, clean the cables with a wire brush. You can also use a water and baking soda solution to help neutralize the corrosion on the terminals. Make sure that you are wearing gloves in doing this step. Clean the battery tray as needed.

Step 7: Insert the new battery. Install the new battery on top of the tray and secure its hold-down bracket by retightening its bolt. Don’t forget to reinstall the battery protective cover if this is applicable.

Step 8: Reconnect the battery cable terminals. Reconnect the positive cable first and then connect the negative one afterward. Retighten the cable clamp nuts and make sure that these connections are tight to prevent sparking.

Step 9: Reinstall the air cleaner housing. Realign back the housing and filter in reverse order of how you removed them, then close the hood.

How to make the battery in a Chrysler PT Cruiser last longer?

The battery life will depend upon how it is maintained, so always take good care of your car‘s battery by inspecting it for any signs of rust or corrosion. You can do this by checking the top and bottom areas for a white powder-like substance, which is typically lead sulfate. If you notice that your car’s battery has begun corroding, it would be best to change it with a new one immediately (if cleaning didn’t work) in order to avoid further damage to other parts of the engine bay.

In addition, you should also have your battery tested to check its performance. Your mechanic will be able to help you best and can test all of its parts using specific tools that will be able to tell if there is anything wrong with any component inside the unit.

How often should you change the battery in the vehicle?

It all depends on the kind of vehicle you have and the type of battery you use. If your car has plenty of electronic components that mostly drain the battery or affect its lifespan, then it may be best to change the battery every five years or less, depending on how frequently you drive the car. If your battery begins to show the signs of weakening, then it is best to change it to ensure that it will not affect the performance of your car.


To keep the battery in your Chrysler PT Cruiser in tip-top shape, you should maintain your battery clean and dry at all times. Do not let it sit idle for a long time as this can cause sulfate crystallization on its internal plates, which reduces the performance and life cycle of the battery. Replace the battery as soon as needed, and don’t ignore the signs that indicate the need to change it. We hope you find this post helpful, valuable, and informative.
