Sulfation can happen to the lead plates contained in wet cell batteries, commonly known as lead-acid batteries, which are fitted in most vehicles. When sulfation occurs, your battery goes dead. Sulfation is a result of the electrolyte fluid level in the wet cells falling below the top of the lead plates, exposing them. The lead plates are unable to retain electrical energy because the electrons can’t flow between the two plates in each cell. Lead plates can’t be scrubbed clean, but you can remove sulfation by reconditioning your battery.

Step 1

Remove the plastic covers from the top of the battery cells. There are either three or six covers, depending on whether your battery is a 6-volt or 12-volt battery respectively. Unscrew the knurled covers using your fingers. If the covers have screwdriver slots, then place a screwdriver into the slots and unscrew them.
