How long is a car battery good for?

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.

What is the white, crusty stuff around my RX-7’s battery post?

If you notice white, crusty stuff around the battery terminals of your RX-7, 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 RX-7’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my RX-7 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 RX-7 owner’s manual for instructions on how to do so.
