Why won't my Tahoe 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 lights on overnight. Stop in for a free battery check at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

What do you do with my dead Tahoe battery?

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

What is the average lifespan of a car battery?

Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.

What is the white, crusty stuff around my Tahoe’s battery post?

The white, crusty stuff that can accumulate around Tahoe 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 Tahoe car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Tahoe owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
