10 Reasons why car battery not charging, and how to fixed it.

Is your Car Battery Not Charging? Have you ever wondered why your car battery starts to fail even if you know that the battery is in a lifetime period?

Sometimes, the car battery tends to fail after a certain time, and the first thing you think is that there must be an error with the battery.

Well, that’s not quite true. There may be no problem with the battery, it may be even in the warranty period, but still, it will not charge because there are problems which you don’t you.

First, it is necessary to identify whether the fault comes from the battery itself or other parts.

For example, the battery may be in perfect condition but may not charge due to electrical problems or errors in other components.

Here, in this battery post, we leave some tips for you to learn to detect problems with the accumulator. Avoid breakdowns, take care of your pocket and take care of your engine.

1. Electrical system failures

According to the above, if parts such as the alternator have problems, the battery will not maintain its charge.

It can also be the brand, especially if you notice that the dashboard lights turn on and the car does not start.

Also, certain installations such as lights, alarms or other accessories may cause unplanned shorts.

Visit your nearest car battery repair shop and make sure you go with experts and that everything you have installed in your car is compatible with its voltage.

2. Lack of charge may be the reason

Surely you forgot to turn off the lights on occasion when getting out of the car.

It has happened to all of us. In that case, if the car battery does not charge, it is because it cannot infinitely retain its voltage.

When you turn on the car, you put into operation a whole system of “recycling” of energy that cannot work with the car turned off.

The solution to this problem is to charge the battery, either with the charging cables or, by visiting the nearest service center. You can also try pushing the car, and turn it on. But, this will not work in an automatic car.

3. Battery leakage

The battery has a mixture of sulfuric acid with water inside (gel in the case of gel batteries).

If you lose this liquid, you will lose the ability to recharge and, retain that load.

If you detect that the battery terminals have whitish dust, the accumulator may leak acid. In this particular case, you can try to push your car to start. When the battery leaks the liquid, it accumulates sulfur around the circuit and connectors.

In this case, it will be ideal to change the car battery. Another reason why car batteries start to fail is the age of the battery. If it is five or more years old, it is time to change it. With the battery voltage reading process, the mechanic will be able to tell you the exact reason for discharging the battery.  

4. Unusable battery

In the most extreme cases in which the car battery is not holding a charge, it will be necessary to replace it.

According to the first point of this post, you must verify that the electrical system is in good condition.

Otherwise, your next battery could be damaged too. Depending on the brand and model, the batteries can last 2, 4 or up to 10 years without needing to be replaced.

If your car battery does not charge for this reason, and you must buy another, make sure you take it to a place where they process it responsibly, as they have toxic materials for the environment. As well as, you must ask the professional to see if there is an electrical problem arises.

5. Extreme Temperatures

There are several reasons why the car battery may fail, but the most frequent is extreme temperatures.

Extreme temperatures, especially the arrival of cold, are one of the main causes that influence the life of the battery as they can cause you to lose starting power.

The problem is usually detected when the vehicle stops starting, but it is possible to avoid starting problems if different measures are taken such as not parking the car on the street, whenever possible, and checking the battery voltage regularly in a qualified workshop.

As the vehicle ages, the battery power may be reduced due to corrosion, sulfur and the passage of time itself. These aspects hinder proper loading. To ensure a good state of charging system and performance, drivers should check their batteries regularly to ensure a good state of charge and performance. You can use the jumper cables to jump-start the car.

6. Most common cause – Irregular use

Many drivers believe that when a car is off it does not consume battery.

This is not correct. Certain systems such as alarms, warning light, closures or “keyless-go” and navigation functions need electricity even when the car is not running and all this contributes to the discharge of the battery.

If this is the problem why your car battery is not holding a charge, you can either remove the system which consumes battery even after the car is turned off or, changing the battery will be an ideal choice. You must check the electrical circuit if there is any short circuit or hidden failure which consumes battery power. 

Therefore, if a vehicle remains stationary in a garage for several weeks, it is very likely that it will not start because of the dead battery. The advice is to start the car once a week for at least ten minutes. These paths recharge the battery again helping to avoid starting problems.

7. Acid stratification

A common cause of car battery failures is acid stratification.

The electrolyte of a stratified battery is concentrated at the bottom of it, which causes the upper half of the cell to have very little acid.

It’s like when sugar settles in coffee or tea because you don’t spin them. Batteries tend to stratify if they are kept at a low charge (below 80%), and never receive a full charge.

Taking short trips with the wipers and air conditioning on maximizes this negative effect. This even damages the proper function of the voltage regulator and alternator. Acid stratification reduces performance overall battery. Always charge the battery in a ventilated environment.

8. Short paths and irregular charging

Short journeys also have a significant influence on battery life.

And, is that when the car runs only the short distances, the battery does not fully charge.

If you use the energy expenditure of some accessories such as the rear windows and heated seats, the cost is even greater and, the battery has a negative energy balance.

So that this does not happen, try to make a long journey with the car at least once a month, so that the alternator can recharge the battery. And, shortly, there will be no alternator problem.

When the batteries are at rest without being charged, they start to sulfate. The longer it rests without being used and with an increase in discharge, the sulfating becomes worse and worse. To eliminate this, pulse or slow charge chargers are used.

9. The small amount of water

Although it may not seem like it, water plays an important role in the electrochemical equation of the battery.

Although most of them are sealed and are maintenance-free batteries. They usually have an indicator of the water level that will allow you to see if these levels are well.

If they are not, then your car battery won’t hold a charge. Low water levels in the battery will cause the electrolyte to lose balance and the battery cells will become very acidic, which will result in the sulfating of their plates.

If you face any problem, visit one of your nearest auto parts store in different parts of the country, and do not hesitate to fill out your contact form.

10. You should charge the car batteries regularly

To ensure that the batteries have a long life, you should charge them frequently after use.

It is the most important thing you should do after using it and, thus prevent it from lowering 20% ​​of the load, since if you do not load it, it will begin to suffer from sulfating.

You can either charge your car battery by turning on the engines or leave it for 10 minutes or, you can use the battery cables to charge it manually.

Conclusion: Start the car before using its accessories

A large number of extra accessories that can work in your car are one of the main factors that the car batteries are discharged and it affects the positive terminal. That is why whenever you want to use the radio or air conditioning of your car, it is recommended that you start the engine before using any components and that you drive the car so that the alternator fully charges the battery. Also, do not leave these accessories on because it will discharge the battery, forcing you to recharge it again. And, if this is done many times, it will also reduce the life of your battery.
