Why won’t my RLX battery hold a charge?

A battery that won't hold a charge is almost 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 favorite Firestone Complete Auto Care to learn more about the state of your battery.

How long can I expect my car battery to last?

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 RLX’s battery post?

If you notice white, crusty stuff around the battery terminals of your RLX, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your RLX’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my RLX 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 RLX 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.
