How To Desulfate A Car Battery. Usually desulfation is achieved by passing high voltage often around 50V through the battery. In some cases the battery can desulfate in a few hours after using a good 12v smart charger.
This ensures both old and newly formed sulfation will be safely dissolved in the shortest possible time. The following instructions explain how to desulfate a battery using a high-frequency battery charger. Desulfation is not a quick process that can reverse all the sulfation occurred.
2 Simple Battery Desulfator Circuits Explored.
The last battery I desulfated for 48hrs is reading 1330vdc after 12hrs initially it read 143vdc the two left to desulfate are reading 1310vdc and 1315vdc they were charged about three days ago. Desulfation may take a day or even two days if the sulfation is particularly heavy. Sulfation occurs when a battery is deprived of a full. If the temperature compensated absorption charging voltage is correct and the.
