  • Why won’t my 740i battery hold a charge? A battery is in its final hour when it will no longer hold a charge. It may be getting old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop by for a free battery test at your local Firestone Complete Auto Care and learn more about your battery's charge.

  • 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.
  • What is the white, crusty stuff around my 740i’s battery post? The white, crusty stuff that can accumulate around 740i car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I clean a corroded 740i battery terminal? Regularly inspecting and cleaning your battery terminals will help keep your 740i’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.
