Why doesn’t my G550 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 may have been leaving your car doors ajar and the dome lights on during the night.

How often should I replace my 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.

Why is there white, crusty buildup on my G550’s battery post?

The white, crusty stuff that can accumulate around G550 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.

What do I do about corrosion on my G550 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 G550 owner’s manual for instructions on how to do so.
