BMW 128i Batteries

Your battery is responsible for providing the electricity that feeds ignition in your BMW 128i. How it does that is actually pretty simple. When you either insert your key into the ignition switch or push the "Start" button, a signal is sent to the battery. The battery converts chemical energy stored inside into electric energy that's sent to the starter and feeds other parts like your wipers.

That chemical reaction, however, can lower the amount of voltage within your battery. The less voltage, the weaker the charge and the harder it is for your battery to deliver the electricity your car needs.

How to Tell if Your Car's Battery is Failing

Fortunately, signs of trouble are easy to spot. They include:

• Dimmed headlights
• A clicking sound when you turn the ignition key or press the "Start" button
• Sluggish engine cranking
• Engine backfires
• You need to press the gas pedal to start your BMW 328i
