What does Desulfating a battery mean?

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 long does it take to Desulfate a battery?

Depending on the size of the battery, the desulfation process can take from 48 hours to weeks to complete. During this period the battery is also trickle charged to continue reducing the amount of lead sulfur in solution.

Does Desulfating a battery work?

If you own a battery desulfator, you can lengthen its lifespan and enjoy even more miles on the road. Plug your car battery into a desulfator and you'll enhance its effectiveness even as it ages.

Can a sulfated battery be charged?

Even when stored fully charged sulfate will form without a frequently applied maintenance charge. It must be charged enough to prevent the battery from dropping below 12.4 Volts* (2.07 volts / cell).

Can you recover a sulfated battery?

Reversible sulfation can often be corrected by applying an overcharge to an already fully charged battery in the form of a regulated current of about 200mA. The battery terminal voltage is allowed to rise to between 2.50 and 2.66V/cell (15 and 16V on a 12V mono block) for about 24 hours.

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).

What causes battery sulfation?

Sulfation occurs when a lead acid battery is deprived of a full charge. This is common with starter batteries in cars driven in the city with load-hungry accessories. A motor in idle or at low speed cannot charge the battery sufficiently.

What is Desulfation mode?

The Battery Sitter's unique automatic desulfation mode works like this: Once the Battery Sitter determines that the battery is sulfated it applies a voltage of up to about 20V at a controlled low current for a maximum period of 2 hours, to recover the battery to the extent that it can again accept a charge using the ...

How long will a reconditioned car battery last?

4. How Long Do Reconditioned Batteries Last? A reconditioned battery can typically last around one year, so you can theoretically extend its life by at least three years if you repeat the process a few times.

Does putting an aspirin in a battery?

Be warned that adding aspirin will shorten the battery life, as the aspirin will react with the sulfuric acid to form acetic acid. Good for a boost, but bad for the innards 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.

What does reconditioning a battery do?

What is Battery Reconditioning. Battery reconditioning means bringing back the healthy life of a battery, that is, full charging capacity and standard electrolyte level. This is important because whether you have a regular car or a luxury type, low charge, and acid stratification are the typical concerns among owners.

Do AGM batteries get sulfated?

This includes the new sealed "dry" such as Optima, Odyssey, Exide and Interstate branded AGM-spiral-wound types. Batteries develop sulfation each time they are used (discharged - recharged). If they are overcharged or undercharged or left discharged, some for even just several days, they will rapidly develop sulfate.

What is a Desulfation charge?

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 pulse charging damage battery?

Absolutely not. This will actually damage your battery and could even lead to an explosion. Attempting to charge a battery in a reverse polarity should NEVER be performed for any reason. For safe, effective prevention and removal of sulfation buildup on battery plates use only our Pulse Technology products.

Is sulfation the same as sulfonation?

Sulfonation and sulfation are two important chemical processes used in many industries to add a sulfur-containing group to an organic compound. The main difference between sulfonation and sulfation is that sulfonation involves the formation of a C-S bond whereas sulfation involves the formation of a C-O-S bond.

What should a 12-volt battery read fully charged?

A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.

Is 11.9 volts enough to start a car?

For a car with a 12V engine, the normal value before starting is between 12.2V and 12.8V, and it should not exceed 14.8V after starting.

At what voltage is a 12V battery dead?

Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means it's about 50% charged.

How do you tell if a battery has a dead cell?
