Here are some simple steps to follow when using a battery desulfator:
- Connect the positive (red) lead from the desulfator to the positive terminal of your battery.
- Connect the negative (black) lead from the desulfator to the negative terminal of your battery.
- Plug the desulfator into a power outlet and turn it on.
- Leave the desulfator connected to the battery for at least 24 hours.
How long should I desulfate my battery for before testing?
If you see an increase in the Specific Gravity (SG) or voltage indicating that there is an improvement in the battery's condition, continue desulfating for an additional 72 hours and retest the battery. Continue this process until the SG or voltage readings no longer increase.
How do you desulfate a battery?
You can desulfate a battery with energy stored through a PWM (Pulse-width modulation) control circuit, which also adjusts amp output. Using this method involves integrating a 555 IC timer. Two transistors intensify the IC’s output, allowing the battery to receive high current pulses.
How long does it take for sulfate to dissolve from Battery?
Allow battery to remain for a minimum of 72 hours before retesting. If improvement is seen, continue until battery voltage reaches full capacity level or no further increase is seen. Note: Do not expect to completely dissolve sulfate in a day. Long established sulfate will require a longer period to be fully dissolved.
What happens if a battery does not qualify for desulfation?
Failure to do so will yield false readings that indicate a battery that is not fully desulfated or does not qualify for desulfation. If no balls float in any cell, the cell is shorted. This means your battery is beyond the point of being properly recharged or reconditioned-desulfated. Dispose of the battery.

How often should you Desulfate a car battery?
If each cell floats three (3) or more balls (or 1250 on gauge-type), your battery can be reconditioned-desulfated. Always rinse the tester with fresh water after every use. Failure to do so will cause false readings.
How long should you recondition a battery?
Set up in a safe and secure area. As an extra precaution, remove the battery caps again as the electrolyte solution will heat up and may overflow during charging. Place the charger as far away from the battery as possible and connect it at a speed of 12V / 2 amps. Let the battery recharge for 36 hours.
Can you over Desulfate a battery?
Batteries develop sulfation each time they are used (discharged – recharged). If they are overcharged, undercharged or left discharged for just a few days, they will rapidly develop sulfate. This condition can be exacerbated with smaller lead acid batteries, such as motorcycle batteries.
How do I know if my battery is sulfated?
The most common sign that a battery could be sulfated is when it does not hold a charge very well or doesn't hold a charge at all, other signs include the battery going dead long before expected or electronic devices not getting the required power they need (ie dim headlights, weak AC, slow start-up).
How does a battery charger Desulfate a battery?
The lead sulfate crystals are broken down (more or less successfully) in the charge cycle. Sometimes some crystals remain, or sometimes a battery is left partially discharged where the crystals of lead sulfate harden, and reduce the capacity of the battery to be charged. This is what desulfation (desulphation)is about.
How do you bring a 12 volt battery back to life?

1. Does a battery Desulfator really work?
A desulfator causes the built-up sulfate crystals in the lead-acid battery to fragmentize. After this process, the sulfur falls into the battery acid, where it dissolves. This occurs when a current pulse flows through the buildup. It can also extend the acid battery life.
2. How long does it take Desulfate a battery?
Desulfation times vary and usually depend on the battery’s size. A deep cycle battery will need an 8-amp setting to desulfate. While this occurs, the battery trickle charges, resulting in less lead sulfur. With that in mind, the entire process could end between 48 hours and a few weeks.
3. How do you Desulfate a battery charger?
Some chargers offer battery desulfation features. For example, a recovery mode option detects sulfate crystals during the charging cycle. From there, it will automatically turn on and apply voltage pulses. However, this process only works for soft sulfation.
4. Exploring a simple battery desulfator
The two methods mentioned below provide simple solutions for battery sulfation.
Conclusion
Overall, desulfation provides the answer if an underlying problem exists with your battery. Not only does this technique cleanse the sulfate crystals from the battery plates, but it also assures longevity. This results from pulses reaching the terminals, causing sulfate to drop and dissolve.

What happens when a battery is overcharged?
Sulfation is a process that occurs in every type of battery when it is overcharged or undercharged; it is the primary cause of battery failure.
What happens when a battery is discharged?
Discharge of the battery (allowing electrons to leave the battery) results in the build up of lead sulfate on the plates and water dilution of the acid. The specific gravity of the electrolyte as measured with a hydrometer in flooded batteries, indicates its relative charge (strength), or level of dilution (discharge).
What does a pulsating DC current do to a battery?
They emit a pulsating dc current that removes the sulfate deposits from the plates and returns them to the battery acid as active electrolyte. When installed permanently, these products also help keep sulfates from building up again so your battery is in peak condition all the time.
What type of plate is used in lead acid battery cells?
A typical lead acid battery cell has two plate types, one of lead and one of lead dioxide, both in contact with the sulfuric acid electrolyte as either a liquid, absorbed in a mat (AGM), or a gel. The lead dioxide (PbO 2) plate reacts with the sulfuric acid (H 2 SO 4) electrolyte resulting in hydrogen ions and oxygen ions (which make water) ...
Why do gel batteries have a lower peak charge voltage?
There is a gassing point to consider, and true gel batteries have a lower peak charge voltage, because bubbles can occur in the gel which don't dissipate, and result in battery damage. More on this in the charging tutorial. The lead sulfate crystals are broken down (more or less successfully) in the charge cycle.
How does lead sulfate work?
The lead sulfate crystals are broken down (more or less successfully) in the charge cycle. Sometimes some crystals remain, or sometimes a battery is left partially discharged where the crystals of lead sulfate harden, and reduce the capacity of the battery to be charged. This is what desulfation (desulphation)is about.
Can you leave a wet cell uncharged?
For this reason, wet cells should not be left unmaintained or uncharged for long periods. The lead used in Gel and AGM battery construction does not require high mechanical strength since it is stabilized by the gel or mat material.
What does "charge" mean in a 900 uh battery?
means that the "charging" current will not reach maximum. magnetic strength. To fully "charge" the 900 uH will take. a considerably longer pulse width. The strength of the inductive kick-back pulse is dependent. upon the degree of magnetic "charge" the inductor acquires. prior to the "discharge" into the battery.
How long does it take for a cell to recover from a pulsing?
