Why won’t my 735i battery hold a charge?

A battery that won't hold a charge is almost as good as dead. It may be getting 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 nearest Firestone Complete Auto Care and learn more about your battery's charge.

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 735i’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 735i 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 a corroded 735i battery terminal?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your 735i 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.
