Why won’t my 525i 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 a habit of leaving your car doors open and the dome lights on during the night.

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.

Why is there white, flaky stuff around my 525i’s battery post?

The white, flaky stuff that can build up around your 525i’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 525i, 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 525i car battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your 525i owner’s manual for instructions on how to do so.
