The chemistry of lead acid batteries makes them more prone to sulfation when exposed to continuous low current and are deprived of a full charge. What starts to happen is that lead sulfate crystals start to form around the negative plates of the battery. As they accumulate they reduce the surface area available for the battery to efficiently release charge.
Drivers who spend a lot of time in congested traffic and idle motor situations will see that the battery can be denied of full charge at that moment. Over a long run sulfination occurs and makes your battery less efficient.
Types of sulfation
There are two types of sulfation, reversible and permanent sulfation. Reversible sulfation is also called soft sulfation and occurs in the early stages of low charge. When proper current is applied soft sulfation will be fixed. The lead sulfate will dissolve and ionize in the solution.
When left for too long hard or permanent sulfation occurs. The lead crystals form stable complexes that are insensitive to charge and won’t reverse the situation. You need to just replace your batteries in that case.
How desulfation occurs
There two natural forces that make desulfation possible, Charge and temperature.When a charge is applied it mobiles the ions to their respective terminals and reduces the amount of idle time they have to combine to form lead sulfate.
As they charge is delivered it also cause the battery to heat. The temperature can be as high as 60 degree Celsius and that contributes to dissolve the lead sulfate crystals and reversing sulfation.
Battery type, use and desulfation
The occurrence of sulfation varies from battery type to usage as well.
In wheelchairs, batteries tend to have a shorter life span because the wheelchairs are used frequently and not enough time for charging is available. The same battery type but in golf carts last much longer because golfers have more time to deliverer a full charge. Actually wheelchair batteries only last half the lifetime of golf cart used batteries.
Lithium-ion batteries do not have any sulfation problems because they use a completely different type of chemistry for a power source. They can actually be damaged by fully charging and are best kept slightly below their full charge if you want them to stay longer.
I recommend them as an alternative to sulfation but they cost twice as much. Their longer lifespan more than compensates for their initial higher purchase cost. They also have lower maintenance costs.
Solar and wind power charging
Solar power has a lower power output and fails to deliver the full charge required to prevent and reverse sulfation.
If you regularly use your solar panel to charge your battery and do not take to a more powerful grid for periodic high current charging your battery life is reduced. People who live in rural areas with no access to the grid will definitely suffer from sulfation. The same applies to wind tunnel powered batteries.
How often must I desulfate?
You need to periodically have your battery fully charged from time to time. A lead acid battery needs 14 to 16 hours of proper charge to achieve full saturation.
A simple overnight charge of 8 hours is not enough to reverse and prevent sulfation.
Sometimes it can be beneficial to own two batteries so that once a week you can have enough time to deliver a full charge as long as may be necessary in your case.
Factors to consider when buying a Desulfator
Desulfator delivers pulses of high current that acts to boost and maintain your battery.
A desulfator of higher current works much better when it comes to dissolving and reversing difficult sulfation. If you use a higher current you will also take much less time to treat your battery.
2. Battery type and usage
Sulfation is only a problem encountered with lead acid batteries. You should only be looking to get a desulfator if you own a lead acid battery. Lithium ion and other dry cell batteries do not use sulphuric acid and hence no sulfation.
Also if you use your battery very frequently such that you don’t have enough hours to rest the device for a full 16-hour charge then you definitely need desulfator.
Level of sulfation
How advanced your sulfation is determines the best size and type of desulfator you will need. If your battery is regular kept charged and well maintained you don’t need a very powerful desulfator.
Once hard crystals form all over the plates then you need some big guns and a desulfator with very high amperage is your only chance to save your battery.

Wrapping it Up
Acting early to prevent sulfation is the best way to save money and increase your battery life.
Our list and guide feature all the best advise you can get on this topic. Followed carefully you should be able to desulfate any battery and increase its life span. There conflicting views on whether these devices can actually reverse the process but research has shown that batteries that are regularly desulfate last twice as long.
1. Is sulfation reversible?
It depends how advanced it is. If you frequently deliver a full charge to batteries then it is possible to reverse any soft sulfation that may have occurred.
Left alone it ultimately becomes irreversible and hard crystals of lead sulfate damage the plates in your batteries.
2. How do I know if my battery is sulfated?
You are able to notice the color charges of the plates when you check the cells. Make sure to always wear a pair of gloves and goggles when you open your battery cells.
The most obvious sign of sulfation is to reduce the performance of your battery. Early sulfation is not visible to the naked eye. If you notice that your battery is not holding enough charge as it used to then you can try using a desulfator to improve performance?
