Why won’t my E320 battery hold a charge?

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

What do you do with my dead E320 battery?

What is the average lifespan of a car battery?

Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.

Why is there white, flaky stuff around my E320’s battery post?

The white, crusty stuff that can accumulate around E320 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 E320 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 E320 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.
