Why doesn’t my Cayman battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead Cayman battery?

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

What’s the cost of DieHard batteries for Porsche Caymans?

Porsche Cayman batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.

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, flaky stuff around my Cayman’s battery post?

The white, flaky stuff that can build up around your Cayman’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 Cayman, 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 Cayman car battery?

Regularly inspecting and cleaning your battery terminals will help keep your Cayman’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.
