Why won’t my 3500 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 free battery test at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.

How long can I expect my car battery to last?

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 3500’s battery post?

A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your 3500 car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

How do I remove corrosion from my 3500 car battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your 3500 owner’s manual for instructions on how to do so.
