Why doesn’t my 300TD battery stay charged?

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 lights on overnight. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

How often should I replace my 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.

What is the white, crusty substance accumulating on my 300TD’s battery post?

The white, flaky stuff that can build up around your 300TD’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your 300TD, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I clean corrosion off my 300TD vehicle battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your 300TD 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.
