How long can I expect my car battery to last?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

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

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

How do I clean corrosion off my Forester vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your Forester’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
