7 Signals of Your Car Battery Failure and How to Maximize its Lifespan

147

There’s no worse feeling than when you put the key in the vehicle’s ignition, turn it, and nothing happens. You try one more time until you realize that it’s nothing but your car battery failure. It is undoubtedly one of the worst feelings for anyone who owns a car. This is one of the most common causes of car breakdown. However, this situation can be avoided.

Some signs warn you that your battery doesn’t have much time to live.

1.    Slow engine start

It takes a lot of time and energy to start your car; the battery produces all that energy. Once you start the engine, the alternator ensures the battery is running by replacing the power used in starting the engine and run the electronic accessories in the vehicle. When you put the key in the car’s ignition and turn it, the battery alone starts the engine.

If the battery is in its last days, you will notice that the motor turns slower than usual. You must see the warning signs, as it is common, you will have only one chance in a slow start before the engine gets to run again. If it doesn’t start at all, the vehicle will only make a quick sound, confirming that the available power is not enough to get it going.

Tip:

Always check your battery if they are in place regularly. Check the battery and see if a change or fix is required.

2.    Electrical components problem

In addition to powering the engine, enough power needs to be produced by the car battery to power all electronics. This implies that electrical components can also be an indicator of car battery failure. There are many electronic accessories in more modern vehicles, including power windows, seats, radio, windshield wiper, instrument panel lights, headlights, and more. All of them require to be supplied with the electrical energy of the battery.

If any of these electrical components start acting strangely, first make sure it’s not a loss of power caused by dirt on the battery terminals. If they are clean, maybe it is time to replace the battery. Pay special attention when you use more than one component at a time. Let’s say a radio is turned on while using the headlights and the headlights start to lose power, the battery may not work as it should.

Tip:

Do not use any car accessories (radio, lights or electronic products) before starting and driving the vehicle. When it’s on, the car’s alternator generates electricity and charges the battery after it has a voltage drop.

3.    Warning light on the instrument panel

The dash of most cars have a warning light, usually in the shape of a battery. It will illuminate if the battery is not being properly recharged or if it is an internal problem. Like the engine check light, the battery warning light could also mean something is wrong with the alternator or some other electrical system. If the light comes on, it is best to have your electrical system inspected by a certified professional to determine what the problem is.

Tip:

Always pay attention to this board, as you will first notice battery failure from the dashboard.

4.    Bloated battery

A car battery is a chemical reaction contained in a box. Just like any chemical reaction, sometimes things can go wrong. When a battery is exposed to constant heat or cold, the case’s flat sides can swell or come off. If, for example, the battery is placed in the vehicle, which is not driven for a time during the winter, the battery will discharge and freeze. Freezing and swelling due to excessive heat commonly result in the battery’s electrical “death,” with no option to be recovered and which must be replaced.

Tip:

Perform a monthly inspection of the battery terminals to ensure they are clean and free of corrosion. One of the main problems that most people have with their car battery is the accumulation of corrosion around them.

 5.    Antiquity

On average, a battery have a five years lifespan. This lifetime will fluctuate depending on the average extreme temperature to which it is exposed, the number of deep discharges, and whether it goes through several full charge cycles or not. Five years is the average life span, so when you turn four years old, it is ideal to let a professional check it, to see how much life you have left. If you’re not sure how much time it has, check the manufacturing date on the box.

Tip:

Check your battery lifespan regularly, to avoid sudden failure.

6.    The intensity of the lights decreases.

The car battery also supplies electricity to the vehicle, so when it begins to lose energy, it is reflected in the car’s functionality.

If you notice that a decrease in the light intensity (both from the headlights and the control panel), or other equipment such as; electric windows or heating work slowly, your battery may be running out of power.

Tip:

You should also take into account the power consumed by the installed elements like light, since it may be necessary to install a battery with a higher capacity so that it does not run out before it is due -check in your workshop

7.    Be guided by sound and smell.

That’s right, some of the symptoms that indicate a failure in your car battery are both the sound and the smell it gives off. On the one hand, you will clearly notice a kind of “cry” when starting the vehicle (in addition to costing more to start), and you will also detect an unusual and somewhat unpleasant odor. These are obvious signs that you are experiencing a car battery failure. Especially in the latter case, it leads to check the car battery, as it can affect other parts of the engine.

Tip:

Protecting the battery from large temperature changes will help maximize its life, you do this using a battery protector.

The symptoms and signs of a damaged car battery are similar to other problems that can occur under the hood, so it’s mostly a matter of guess to tell whether you’re dealing with a faulty car battery or not.

If your vehicle has one or two of the following symptoms listed above, it does not mean that the car battery is the problem. However, the probability of a dead, dying, or faulty car battery increases as more signs show up. Make sure you go through the signs to easily detect car battery failure causes before more signs show up.
