What is sulfation of batteries?

Sulfation 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 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.
