Why won’t my 325is battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

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.

What is the white, crusty stuff around my 325is’s battery post?

If you notice white, crusty stuff around the battery terminals of your 325is, 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 325is’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my 325is car battery?

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.
