You won't be able to start your vehicle if the battery goes dead. That is why it is important to recognize the signs that indicate your battery needs to be serviced or replaced. You may notice that the lights on your dashboard are flickering. This is something that many people ignore, but you should have your battery inspected if you notice this. The windows are something else that you need to pay attention to. If they roll up and down slowly, then this may be caused by the battery. However, this is a problem that can also be caused by physical resistance.
Additionally, the age of the battery is something else you should pay attention to. Your driving habits and the weather are two of the main things that affect how long your battery will last. However, it may need to be replaced if it is more than five years-old.
