Why doesn’t my 330i 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 been leaving your car doors ajar and the dome lights on during the night. Stop by for a free battery test at your favorite Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead 330i battery?

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

How much do DieHard batteries cost for your BMW 330i?

BMW 330i 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 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.

Why is there white, flaky stuff around my 330i’s battery post?

The white, flaky stuff that can build up around your 330i’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 330i, 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 clean a corroded 330i battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your 330i’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.
