Why doesn’t my LS400 battery stay charged?

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 a habit of leaving your car doors open and the lights on overnight. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care and learn more about your battery's charge.

How long do car batteries 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 stuff around my LS400’s battery post?

If you notice white, crusty stuff around the battery terminals of your LS400, 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 LS400’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded LS400 battery terminal?

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 LS400 owner’s manual for instructions on how to do so.
