Why won't my CTS battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop by for a free battery test at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead CTS battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

What’s the cost of DieHard batteries for Cadillac CTSs?

Cadillac CTS batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.

How often should I replace my car battery?

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.

What is the white, crusty substance accumulating on my CTS’s battery post?

The white, crusty stuff that can accumulate around CTS 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 CTS car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your CTS owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
