Why won’t my 735iL 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 been leaving your car doors ajar and the dome lights on during the night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

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 735iL’s battery post?

If you notice white, crusty stuff around the battery terminals of your 735iL, 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 735iL’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded 735iL battery terminal?

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.
