2 Indicators That Your Car Has A Dead Battery

Posted By in Car Tips | No Comments »

One of the most common reasons why a car won’t start is a dead battery. This is a fairly easy problem to fix, though it can be very inconveniencing to find that the car won’t start at the last minute, forcing you to change your plans to get to a garage instead.

Does Your Car Have A Dead Battery?

Fortunately, there are several indicators that your car has a dying or dead battery, which you can look for to take the necessary steps in a timely manner. Common warning signs of battery failure include:

  1. Engine won’t crank

    For the car’s engine to start and run, it must crank fast enough and fire promptly. When starting your car, the battery supplies power to the starter, which then cranks the engine until it fires. When the engine has fired, it “idles” until you engage a gear for it to move.

    But when you find that turning the key does not crank the engine, or if it cranks very slowly and produces an unusual sound, then it is possible that the battery is dead and needs to be charged. One way to charge the battery is by jump-starting it, but if it is too drained, you should opt for the longer “trickle” charging instead.

  2. Low or no accessory power

    If the battery is dying, you might notice that the headlights or interior lights are much dimmer than normal. When you have no power at all, the lights, headlights, and radio won’t even turn on. But if the lights on the dashboard stay dim when they come on, then the battery is not completely dead. However, it is unlikely that it has enough power to crank the engine fast enough for it to fire. So, consider charging the battery using either of the methods mentioned above.

    If your accessories are working but the engine still won’t crank, it is possible that there is an electrical problem, such as a failed starter or starter solenoid, a faulty ignition switch, or a poor electrical connection in the ignition circuit. To identify the actual problem, seek the help of a certified mechanic.

Final note

When you find that you have to jump the battery three or more times a week, this is a sign that your battery is about to die, and should be replaced. However, you should bear in mind that it is fairly normal for cars to start with a bit of difficulty in very cold weather because it is hard for the gas to vapourize, plus the battery only releases half the power it normally does.
