How Long Does It Take To Desulfate A Battery?

If you have a car and use the battery, you’ve probably run into a weak battery problem. Aside from significant battery problems like broken battery cases and leaks, sulfation buildup is the most common cause of early battery failure.

Regarding lead-acid batteries, sulfation is a problem that is a weakness in a car. But you can solve this problem with desulfation. This process gives dead battery cell new life.

If you are looking for how long does it take to desulfate a battery? The times vary depending on several factors, including the desulfated battery size. In this article, we have discussed to know more about it. 

What is battery sulfation?

Before learning about battery desulfation and the time it takes, it is necessary to understand what battery sulfation is.

Lead-acid batteries, which are the most common kind used in cars, can have a problem with sulfation. It is nothing more than the accumulation of lead sulfate crystals on the lead plates within the battery container. 

The plates combine with electrolytes to generate lead sulfate during power production. The formation of lead sulfate on lead plates is known as sulfation.

How long does it take for a battery to desulfate?

If it is a sulfated battery, the process of desulfation it may take up to 48 hours or possibly a few weeks. In rare circumstances, the battery may desulfate in a few hours after using a decent 12 volt battery charger.

If the sulfation is especially heavy, desulfation may take a day or two days. Using trickle charging, it will only need a couple of charges to go back to full power. When desulfating a battery, the time that it will take to finish the process can vary based on several factors:

  • Depending on how much sulfation has happened in a battery, how big it is, and what technique you choose to desulfate it, it might take a few hours to a few days.
  • The procedure may not begin if you use sea salt or soda to desulfate your battery. When sea salts are employed, a battery’s resurrection might take several weeks.
  • If you don’t get the voltage reading after battery charging, the battery must be discharged and fully charged battery again.
  • In some instances, the desulfation process may take some time to complete.
  • There are also several elements to consider, including the battery’s state, the quantity of sulfation, and how the battery is desulfated.

Different ways for desulfation lead-acid batteries

There are several ways to desulfate a car battery. But here we have selected the most common three. Let’s have a look then.

Epsom Salt

When desulfating batteries, using Epsom salt is the most efficient and safest way. The desulfation process’ principal medium is Epsom salt. Due to its ability to reduce battery acid accumulation.

The Epsom salt solution is used as part of this procedure to attempt to improve the skin. Reconditioning a battery using this approach involves dissolving Epsom salt in enough water to produce the solution and then pouring it into the cell.

Battery Reconditioning

For the most part, this is the most common process of desulfurization, and it’s the most common way of reconditioning batteries. The battery reconditioner creates high voltage pulses to eliminate sulfate accumulation on the battery plates. 

Desulfating using Chemicals:

Desulfating batteries with chemicals is an additional method. It requires the use of a chemical. Once you put the chemical on the battery, now it will do its job. This strategy may be successful; however, there is a counterargument that it is not the best.

How to keep a battery from sulfating? Some preventing measures

Even though there is no way to stop a battery from sulfating completely, you can do things to keep your battery from getting too much sulfation.

  • Charge your car’s battery while not in use. Even if you put the battery away, ensure the voltage doesn’t drop below 12 volt.
  • Don’t put a battery anywhere that is hotter than 75 degrees. When the temperature goes up, the battery tends to lose power faster.
  • Don’t let your batteries get too low on power.
  • Make sure that the electrolyte level isn’t low. 
  • Don’t leave your battery in a state where it’s almost dead or dead for long periods. It makes the sulfation build-up harder, making it harder to get rid of.

Conclusion

Desulfating a lead dioxide battery takes the sulfate crystals off the lead plates. This article on how long it takes to desulfate a battery has discussed all the tips and techniques to help you remove sulfate from the battery. 

Whichever method you pick, follow the directions carefully to prevent harming the battery.
