While there are anti-sulfation devices available that will apply pulses to battery terminals to prevent and reverse sulfation on a healthy battery, they will not reverse the damage completely and are not always recommended. Increasing the battery temperature to 50–60☌ (122–140☏) during the corrective service further helps in dissolving the crystals. 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. 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. While these can sometimes be salvaged, it is unlikely that restoration is possible. Permanent sulfation occurs when a battery has been in a low state-of-charge for weeks or months. However, doing so should only be done by someone with experience working with lead batteries, such as the retail outlet where your battery was initially purchased.
If the problem is recognized early enough, it is possible to reverse the sulfation of a battery. Their names imply exactly the effects on your battery. There are two types of sulfation that can occur in your lead battery reversible and permanent. A battery is stored without a full charge.But, sulfation builds up and causes problems when When your battery has a buildup of sulfates, the following can happen:Īll lead acid batteries will accumulate sulfation in their lifetime as it is part of the natural chemical process of a battery. When too much sulfation occurs, it can impede the chemical to electrical conversion and greatly impact battery performance. Sulfation occurs when a battery is deprived of a full charge, it builds up and remains on battery plates.

The damaged caused by battery sulfation is easily preventable and in some cases, can be reversible.
A Sulfated battery has a buildup of lead sulfate crystals and is the number one cause of early battery failure in lead-acid batteries.
