How long do car batteries 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.

Why is there white, crusty buildup on my Montero Sport’s battery post?

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

What do I do about corrosion on my Montero Sport 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 Montero Sport owner’s manual for instructions on how to do so.
