How long do car batteries last?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

Why is there white, crusty buildup on my XTS’s battery post?

The white, crusty stuff that can accumulate around XTS car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

What do I do about corrosion on my XTS car battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.

Shopping for Cadillac XTS Car Batteries

Your XTS doesn't have an expiration date, but its battery does. On average, auto batteries last anywhere from three to five years. Check your battery regularly and replace it as needed so it doesn’t leave you and your Cadillac XTS stranded. Watch for signs that your current battery is getting too old or too weak. A slow engine crank, an illuminated check engine light or battery signal, swollen battery case, corrosion-covered posts, or weak lights can all signal that your battery is waving goodbye.

Or, you can get a complimentary battery check at your nearest Firestone Complete Auto Care. With computerized testing we can see how much charge is left in your battery.
