Why won't my Elantra battery stay charged?

A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop by for a free battery test at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

How long can I expect my car battery to last?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

Why is there white, flaky stuff around my Elantra’s battery post?

The white, flaky stuff that can build up around your Elantra’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 Elantra, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

What do I do about corrosion on my Elantra car battery?

Regularly inspecting and cleaning your battery terminals will help keep your Elantra’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
