Why doesn’t my LaCrosse battery stay charged?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead LaCrosse battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

How much will replacing my Buick LaCrosse’s battery cost if I get a DieHard battery?

You can find affordable LaCrosse batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.

How often should I replace my 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.

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

The white, flaky stuff that can build up around your LaCrosse’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your LaCrosse, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I remove corrosion from my LaCrosse 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.
