Signs of a Failing Car Battery

Most people take the parts that make their cars function for granted. They just expect them to work without fail. However, the truth is that failures do occur, and it is not uncommon for them to leave drivers and their passengers stranded when they do. Thankfully, you may be able to avoid such a headache, though. For instance, if your auto battery begins to show early signs of failing, you can replace it to ensure that your vehicle will crank and run as it should.
 

Let’s learn about some of the signs of a failing auto battery. Then, if they show up, you can take action to prevent your car from giving you fits. 
 

A Clicking Sound
If you get into your vehicle and turn the key in the ignition, only to be met with a clicking sound in your ears, you probably have a weak or dead battery on your hands. This is because when functioning correctly, the auto battery sends a current to the starter solenoid. Then, the starter moves, turning the motor over. However, when failing occurs, the current to the starter isn't strong enough, and that dreaded clicking becomes part of the picture. 
 

Dimmer Than Normal Headlights
When driving in the darkness, your car's headlights shine brightly and allow you to see. If this is something you do regularly, there's a good chance you know how vivid the bulbs should illuminate. So, if you're having problems seeing one day, get out, and find dim headlights, it could be time to get your auto battery tested, as it might be failing. Of course, the dilemma might stem from other issues, like weak bulbs or bad electrical connections. But often, when a vehicle's headlights are dimmer than usual, a bad auto battery is the culprit. 

The Check Engine Light Turns On
It seems like a vehicle's check engine light will turn on for anything and everything these days. For example, if you have a loose gas cap, illumination may occur. How about a bad oxygen sensor? Yes, that's another reason the onboard computer might get a signal and tell the light to shine. But what about a failing auto battery? That, too, can lead to the check engine light blinding you from the dash.

Because so many different things could be to blame for the check engine light turning on, you probably shouldn't just begin replacing parts. That might result in you buying tons of items before finding the right one, and that can get pretty expensive fast. Instead, take the vehicle to an auto parts store or mechanic with access to diagnostic equipment. They can use a scan tool to see what code has been thrown and pinpoint what is failing.

Hopefully, these signs will help you determine when your auto battery is failing you. Don't only count on them, though, as there are other causes. If your car starts doing something out of the ordinary, contact Nucar CDJR of Tilton in Tilton, NH,  to schedule a diagnostic service.
