Why is My Battery Light On?

There are many dashboard symbols and lights that clue you in on things going on under the hood of your car. The battery warning light, which looks like a battery with a positive and negative sign, could come on while you’re driving, which means that your battery charging system may not be working as it should.

It could also mean that something else has gone wrong with your engine or one of its components. There are many possible explanations for why a battery light is on, many of which require your attention.

At Montgomeryville Nissan, we want to do all we can to help our local customers in Lansdale and Doylestown areas stay safe on the roads, which is why our service center has put together this article to inform you of the many reasons your battery light could go on.

Problems with the Battery

Your battery could have damaged cells or plates inside of it, corroded cable terminals, or leakage that impact its ability to recharge. If this happens, it can cause your battery light to go on.

Problems with the Charging System Connections

There are many cables and wiring components within your charging system. If any of them become loose or corroded, it can cause a fault that makes your battery light go on.

Is it the Alternator or the Battery?

Your vehicle’s alternator generates the power that’s stored in the battery. An issue with the alternator, a loose or broken accessory belt that drives the alternator, or a malfunction with the voltage regulator could all impact your battery charging.

Signs the Battery or Charging System Aren’t Working Properly

Your battery light should go on when you first start your car, then go out after a few seconds. If it turns on while you’re driving, that means some aspect of your charging system has a malfunction.

You can also monitor your battery’s health by looking at your electrical components. If your charging system isn’t working properly, your headlights or interior lights could be dim or flickering, and you may lose time on your vehicle’s clock.

What to Do If Your Battery Light Turns On

If you do happen to be driving when your light turns on, you should be able to make it a short distance. You can try to drive it home or to the nearest service center since the car can still run if the battery has a little charge left. To conserve as much battery power as possible, turn off any electrical components you can, such as the stereo, heat and air conditioning, and avoid using your power accessories, like your windows or seat adjustment, until the issue is taken care of.

If the charging system is malfunctioning, however, your vehicle will stop running once the battery is drained. If your vehicle is off when this occurs, you won’t be able to restart it, since the battery supplies the power for the starter motor.
