Why won't my LS500 battery stay charged?

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 free battery test at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

What is the average lifespan of a car battery?

A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.

What is the white, crusty substance accumulating on my LS500’s battery post?

The white, crusty stuff that can accumulate around LS500 car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

How do I remove corrosion from my LS500 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.
