Why won’t my 635CSi battery hold a charge?

A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop in for a free battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead 635CSi battery?

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

How much do DieHard batteries cost for your BMW 635CSi?

You can find affordable 635CSi batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.

How often should I replace my 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 635CSi’s battery post?

The white, crusty stuff that can accumulate around 635CSi 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 corrosion off my 635CSi vehicle battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your 635CSi 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.
