Before we get to the best battery Desulfators available on the market, let’s start with the meaning and purpose of the battery desulfator. Most car owners do not understand the car batteries and the use of desulfator.

Also known as battery regenerator, do not confuse the functionality of the product with its name. Regenerators are supposed to fix all kinds of batteries and add life to them, no matter how damaged they are. But, that is not the case with the desulfators. If the battery of your vehicle is acting up due to some serious damage, then know that no desulfator is capable of fixing it. As the name suggests, the desulfator is used to remove the buildup of sulfate on the lead plates. As the sulfate developed on the battery’s lead plate hardens, it interrupts the battery performance.

In fact, that’s the reason why most batteries work effectively for a specific period until they gradually start to lose their capacity. The major purpose of the battery desulfator is to restore the lost capacity of the battery due to sulfate formation on the lead plates. It doesn’t only restore the capacity of the battery, but improve its durability and performance. Other names of battery desulfators are regenerators, reconditioners, and pulse conditioning products.

What Is Battery Desulfator?

Lead batteries tend to lose their capacities over time. But, keeping your batteries uncharged for hours and days or leaving it half-charged can result in the buildup of sulfate deposit on the lead plates. As these deposits get harder over time, your battery gets sulfated. It gives poor performance.

Basically, the battery won’t be able to charge to its actual capacity that it did when you purchased it. If you keep repeating this mistake, the battery capacity will reach a point where it will become technically impossible to charge anything from the battery. The last resort will be to replace the battery with a new one. But, if sulfation is the cause of poor battery performance, then there is nothing to worry about.

The desulfators dissolve the sulfate deposits on the battery’s lead plates. You may even notice the flakes of sulfate particles coming off the battery. Basically, the desulfator is responsible for removing the buildup of sulfate from the lead plates. As a result, it restores the life and actual capacity of the battery that had been lost to sulfation. You might be wondering why such an amazing product isn’t that popular in the battery industry. Well, the battery manufacturers earn a significant profit from replacement batteries. The sulfation process that affects battery performance and lifespan is somewhat beneficial for battery manufacturers. After all, it gets people to swap their old battery with a new and fresh one.

Things to Consider Before Buying Battery Desulfators

Sulfation is considered to be the number one cause of battery failures in most cases. The buildup of sulfate deposit on the lead plate may not affect your battery’s life or performance instantly. But, it develops gradually and the battery capacity will grow smaller over time.

There are not many ways to avoid sulfation since it is a natural process. Believe it or not, but sulfation will happen at some point even if you take good care of your car’s battery. But, there are definitely some ways you can slow down the process or repair the battery if it has reached a point where it doesn’t power any automobile system.

Make sure that you charge the battery completely before using it. Moreover, leaving your car’s battery uncharged for an extended duration can also affect its performance and capacity. So, charge the battery fully and use it carefully. Another important thing is to desulfate your batteries as soon as you notice the initial signs of sulfation. The sooner you get it repaired, the better its performance will be. Remember that sulfation can lead to internal damage and other severe issues.

Here we have mentioned a few important factors you need to consider when buying battery desulfators for your car’s battery. Let’s have a look:

High-frequency Electric Current

No matter which product you choose, it must send electric currents to the battery to remove the buildup of sulfate from the lead plates efficiently. It is the easiest and fastest way to get rid of the sulfate formation on the lead plates.

Desulfator Diagnosis

Not all products offer additional features, but some desulfators come with some bonus features that scan your battery and detect other possible issues that can affect its performance. This gives you an idea of how your battery is performing. This also helps you to identify if your battery needs more than a desulfator.

As mentioned before, the desulfators are not enough for the batteries with internal damages. You will need to either regenerate the battery or get it replaced. A desulfator that can diagnose the battery will reveal all the internal damages in the battery.

Monitoring

As soon as you have connected the product to the battery, it will inform you about the current status and progress of the battery. In fact, some desulfators come equipped with an LED indicator that has been proven useful in monitoring and displaying the status of the battery.

Sulfation is Reversible

When your charge and run your battery, the sulfates start to develop on the plates. Charging also leads your battery to gassing, a process that converts sulfate crystals into sulfuric acid. When you keep your car batteries undercharged or not charged at all, the sulfation grows intense and it gets super complicated for the battery to reverse sulfation on its own.

But, as mentioned in this post, it is absolutely possible to restore the performance and battery life of your automobile’s battery by using a desulfator. Designed specifically to break down the sulfate particles accumulated on the lead plate, a desulfator sends electricity in pulses to reverse sulfation. In fact, a desulfator is so strong that it can remove the hardest and stubborn sulfate particles. They do it by exposing this sulfate to an extremely high voltage.

Some desulfators can restore performance in almost dead batteries. However, we highly recommend you get the process done as soon as possible. Sulfation affects your battery slowly. So, it is best to desulfate the batteries when you notice the first signs.

The Sulfation Process

Sulfation is one of the common issues in lead-acid batteries. Now that most of the cars feature lead-acid batteries, it goes without saying that sulfation can affect your battery’s performance anytime.

An important thing to note is that sulfation isn’t an overnight process. It takes time for your batteries to form the sulfate deposits on the lead plate. In fact, there is a chance it will never happen to some lead-acid batteries. Basically, it depends on how well you take care of the battery. If you often leave your car battery uncharged in the garage for an extended duration, then it will start to develop sulfate deposits. It is, therefore, important for car owners to charge their batteries to its fullest capacity, especially if you are planning a long drive.

Battery desulfation occurs when you use your car battery to power the air conditioner, lighter, radio, and other such battery-powered systems and do not bother to charge the battery. To maintain the performance of your battery, you will need to use and charge it regularly. Sulfation has become so common that it can occur in batteries that aren’t being used for months. So, you are wrong if you think storing your car battery in the garage will save it from sulfation and damages. Each battery comes with a natural capacity. Even if you don’t use your battery, it will be discharged automatically.

In some cases, the batteries stored in the garage for days and weeks charge either really slowly or do not charge at all. This indicates sulfation. So, remember that the frequent use of the car battery is not the only thing that causes sulfation. However, this is one of the most common and fastest ways for sulfation to occur.

Final Words

You can’t stop sulfation even if you stop using your battery or do not charge it at all. It is a natural process and will happen at some point. But, you definitely have some cheaper options to get the performance and capacity of your battery restored. Instead of shelling out on battery replacement, you can diagnose the issue and desulfate the battery.

The battery desulfators mentioned on this list are some of the quality brands. Check and compare the features and select the best one.

  1. Does Your Battery Need a Desulfator?

    Usually, when your battery doesn't give optimal performance, you take it to the nearest local store to get the issue fixed. You end up getting your battery replaced. Buying a desulfator will be a waste of money if your battery's performance is affected by internal damage. So, you can't just by a desulfator hoping that it will repair all types of damages.

    The first step to improving your battery's performance is to test the battery for sulfation. Fortunately, you can do it on your own. You can even diagnose other problems in your battery. All you need is two essential tools for battery performance diagnosis. This includes the temperature compensated hydrometer and a voltmeter. These diagnosis tools are effective in testing a 12 or 34-volt battery for sulfation. If sulfation is the only issue that's affecting the battery performance, then you already know the next step.

  2. What Types of Batteries are more Prone to Sulfation?

    It is important to know that sulfation is a natural process and affects all types of batteries at some point. Every time you charge and run your battery, the small particles of sulfate forms on the lead plates. However, certain batteries that remain undercharged for weeks or partially charged are at high risk of sulfation.

    Undercharging your batteries can trigger sulfation faster than the fully charged batteries. Though sulfation is still possible in the fully charged batteries, it minimizes the sulfation effect. Your battery is at a low risk of sulfation if you often drive your vehicle on the highway. City drivers, on the other hand, are at high risk of sulfation.

  3. How to Know if your Battery is Sulfated?

    It is quite easy to detect a damaged battery. However, you will need to take it to an automobile expert or buy the battery assessing tools to know if the reason for this damage is sulfation. Decreased efficiency is the most common sign of a sulfated battery. These batteries do not charge well.

    If you are unable to power the air condition, cigarette lighter, music system, and other electronic devices in your vehicle, then that’s a clear sign your battery is sulfated. Visual diagnostic on the battery is possible. However, you will need to open the battery and take out the caps with mechanical tools. So, it is better to leave it to a professional. Usually, a sulfated battery features grey and grubby cells. A healthy car battery, on the other hand, will have silver cells.

  4. How Much Time Does the Desulfator Take to Fix Your Battery?

    It depends on the desulfator you choose and how much your car battery is sulfated. That is the reason why we recommend you desulfate your batteries as soon as you notice the initial sulfation signs. The process can take from 48 hours to a few weeks. It totally depends on the amount of sulfate accumulated on the lead plates.

    In the meantime, you will have to keep charging your battery until you notice the results. If you leave your battery uncharged for several days, there is a good chance it will end up in permanent sulfation. If that happens, the desulfator will take weeks to reverse the process.

  5. Can Battery Desulfator Fix all Types of Battery Issues?

    Desulfator sends strong electric pulses to break down the sulfate on the plates. However, it is possible for a desulfator to not bring the dead battery to life. This is especially possible when the battery is so internally damaged that no amount of electric pulses or voltage could restore its performance.

    Also, the desulfator may not work if your battery has got internal damage due to other reasons. In such cases, you will need to replace the battery or get it to an automobile repair shop.
