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

How long can I expect my car battery to last?

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 substance accumulating on my Cayman’s battery post?

A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Cayman car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

How do I clean corrosion off my Cayman vehicle 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.
