Older lead-acid batteries were made from cast lead plates onto which a paste was loaded. These plates and separators were then stacked, generally with negative plates on both sides, so there was always one more negative plate than the positive plate. Batteries were often called 7-plate, 9-plate, or as many as 17-plate batteries.
You can recover the oxides (covered later in the article) from the positive plates that have fallen victim to the anodic corrosion and use it to make paste for the new plates. The negative plates suffer from sulfation but that can be ignored. So; we will be using the negative plates to make a new cell with the paste that comes from oxides.

Lead-acid batteries are usually made up of six cells, each containing a positive plate made of lead dioxide, a negative plate made of metallic lead, and an electrolyte solution of sulfuric acid. When the battery is discharged, the lead dioxide and lead plates react with the sulfuric acid to form lead sulfate.
Usually, the number of negative plates in a lead–acid cell exceeds the number of positive plates by 1 ((n) positive plates and (n+1) negative plates). In this case, the utilization of the NAM (about 46–48%) is lower than the utilization of the positive active mass and the cell capacity is determined and limited by the positive plates, if ...
