Why doesn’t my i8 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. Stop by for a complimentary battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.

What is the average lifespan of a car battery?

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 i8’s battery post?

If you notice white, crusty stuff around the battery terminals of your i8, 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 i8’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my i8 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 i8 owner’s manual for instructions on how to do so.
