Why won’t my Elantra battery hold a charge?

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 complimentary battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.

How long is a car battery good for?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

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

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

Regularly inspecting and cleaning your battery terminals will help keep your Elantra’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
