Why won’t my 300TE battery hold a charge?

A battery is in its final hour when it will no longer hold a charge. It may be getting 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 and learn more about your battery's charge.

What do you do with my dead 300TE battery?

What’s the cost of DieHard batteries for Mercedes-Benz 300TEs?

What is the average lifespan of a car battery?

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, flaky stuff around my 300TE’s battery post?

The white, crusty stuff that can accumulate around 300TE 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.

How do I clean a corroded 300TE 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.
