Why won't my 750iL battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the lights on overnight. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.

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 750iL’s battery post?

The white, crusty stuff that can accumulate around 750iL 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 750iL 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 750iL owner’s manual for instructions on how to do so.
