Having a dead battery in a car is extremely frustrating. You could be out at the mall shopping and it’s the middle of winter, you come outside, walk to your car, place your bags in the back seat, slide into the driver’s seat and breathe a sigh of relief that you’re safe. Put the key in the ignition, turn it to the on position, then turn it a little bit more and all you hear is this familiar click sound.
Maybe you were lucky enough and the engine started turning over but then died and that clicking sound hit you. That clicking sound is your starter trying to begin turning but not getting enough amperage to do so.
Winter stresses the battery out much more than summer because of the temperature. The colder the temperature, the more cranking amps are required to turn the engine. When that engine is extremely cold, it is difficult to turn those moving parts.
Before getting into that situation with a dead battery at the mall or at your office, here are three signs that may indicate your BMWs battery may be failing.
Sign #1: You already had to jumpstart it recently.
You might have left the lights on, the dome light on, or something else in the BMW while you were at work or home, and if that’s the case, it may have been a one-time thing. Yet, if you had to jumpstart the battery recently, it’s a pretty good indicator that there something wrong with it.
Sign #2: It seems that the headlights are a bit dimmer all of a sudden.
When you’re driving and notice the headlights or even the dashboard lights seemed dimmer than you have been accustomed to, it might not be your eyes playing tricks on you. If the alternator goes bad, the battery will be used to run the engine and all of the electronics.
If the headlights suddenly begin to dim, the battery is getting close to dying. It’s time to pull over to a safe place and call for assistance.
Sign #3: The engine struggles to life after sitting idle for a long time.
If the engine has a difficult time turning over, even in warmer conditions, it could be that the battery simply doesn’t have the amperage it used to.
If you notice any of these situations arising, bring your BMW to an authorized service center as soon as possible to have the battery tested, the alternator inspected, and the battery replaced, if needed.
