Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery’s capacity and eventually rendering it unusable.
The electrolyte in a lead-acid battery is sulfuric acid, which acts as a conductor for the flow of electrons between the lead plates. When the battery is charged, the sulfuric acid reacts with the lead plates to form lead sulfate and water.
Many services to improve the performance of lead acid batteries can be achieved with topping charge (See BU-403: Charging Lead Acid) Adding chemicals to the electrolyte of flooded lead acid batteries can dissolve the buildup of lead sulfate on the plates and improve the overall battery performance.
To put it simply, lead-acid batteries generate electrical energy through a chemical reaction between lead and sulfuric acid. The battery contains two lead plates, one coated in lead dioxide and the other in pure lead, submerged in a solution of sulfuric acid.
Adding chemicals to the electrolyte of flooded lead acid batteries can dissolve the buildup of lead sulfate on the plates and improve the overall battery performance. This treatment has been in use since the 1950s (and perhaps longer) and provides a temporary performance boost for aging batteries.
Flooded lead-acid batteries are made of lead and lead oxide electrodes dipped in a dilute solution of sulfuric acid. These batteries require regular maintenance, including adding distilled water to maintain the electrolyte level and cleaning the terminals to prevent corrosion.
