Commonly Asked Cayman Battery Questions

Firestone Complete Auto Care has answers to your top car battery questions. If you have battery questions that are Porsche Cayman-specific, visit your nearest store. Our expert techs have the answers you need.

  • Why won’t my Cayman battery hold a charge? A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you may have been leaving your car doors ajar and the cabin light at night. Stop in for a free battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my dead Cayman battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  • How much will replacing my Porsche Cayman’s battery cost if I get a DieHard battery? 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.
  • What is the average lifespan of a 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, 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.
  • What do I do about corrosion on my Cayman 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 Cayman 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.
