What causes sulfation in a lead acid battery?
Sulfation happens inside Lead–acid batteries when the electrolyte starts to break down. As the sulphuric acid (electrolyte) splits up, sulfur ions become free forming crystals. These sulfur ion crystals then stick to the lead plates of the battery, thus forming lead sulfate crystals.
How do you remove sulfation from a lead acid battery?
Fill the lead-acid battery cells up to the maximum marker using distilled water. Leave the cell covers off. You will heat the plates during the recharge process, which will help dissolve the sulfation.
How do you reverse sulfation?
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.
What is meant by sulfation of lead acid battery?
Sulfation is the formation or build-up of lead sulfate crystals on the surface and in the pores of the active material of the batteries’ lead plates. During normal use of the battery the formation of lead sulfate crystals is only temporary, they disperse during the recharging process.
How long does Desulfating a battery take?
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.
How do you Desulfate a deep cycle battery?
To dissolve the Epsom salt more easily, use hot distilled water for this stage. You may use the same approach as you did with the baking soda and dissolve in smaller quantities. Pour the Epsom salt solution into each cell of the battery in the same way you did the distilled water and baking soda solution.
Can you recover a sulfated battery?
A sulfated battery is the most common malady of a dead battery, but as long as an used lead acid battery is mechanically sound, a sulfated battery can be revived.
Does Desulfating a battery work?
we recommend the Battery Extra desulfator, it works on sulfated batteries but not on batteries with internal cell damage. You need to make sure that you get the correct model, the models range from 12 volt to 120 volt and for batteries up to 3,000 Ah the website for the Battery Extra is spam.
What does battery sulfation look like?
The most common sign of a sulfated battery is one that will not charge very well, or simply refuses to charge at all. If you suspect your electronic accessories are not receiving enough amperage (weak a/c, dim headlights) it is a strong sign that your battery is sulfated.
How long should you Desulfate a battery?
Desulfation Techniques However, this method of desulfation takes three to four weeks normally throughout which the battery must be trickle charged i.e. charged in parallel to the desulphator so that the battery gets rejuvenated and completely charged.
