Two lead plates after being subjected to hundreds of reversals will acquire a skin of lead peroxide thick enough to process sufficiently high capacity. This process of making positive plates is known as formation. The negative lead acid battery plates are made by same process.
When the plates are connected together, they make up the battery grid. There are two methods for manufacturing plates: oxide and grid production, and pasting and curing. The first step in oxide and grid production is making lead oxide. There are a few options for manufacturers to create lead oxide from lead ingots.
