What is sulfate of batteries?
Feb 14, 2012
Sulfate is the formation or deposit of lead sulfate on the surface and in the pores of the active material of the batteries' lead plates. If the sulfate 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 sulfate are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging.
