What Is Sulfation of Batteries?


Sulfation is the formation or deposit (on lead-acid-batteries) of lead sulfate on the surface and in the pores of the active material of the battery lead plates. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all. Common causes of battery sulfation are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging.
