A lead-acid battery acts as a store of power because of the reaction between the lead plates and the electrolyte. The reason that both sulfation and acid stratification cause batteries to lose power and the ability to accept charge is because they both reduce the contact between the lead plates and the active electrolyte.
At the same time the more watery electrolyte at the top half accelerates plate corrosion with similar consequences. When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely.
The actual process is dependent on the type of battery we are talking about. In a lead acid battery, The cell voltage will rise somewhat every time the discharge is stopped. This is due to the diffusion of the acid from the main body of electrolyte into the plates, resulting in an increased concentration in the plates.
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.
All lead-acid batteries suffer from sulfation. It’s just chemistry. Lead-acid batteries contain lead plates and a free-flowing solution of sulphuric acid. One of the inevitable byproducts of the plates and acid coming into contact is that lead sulfate will accumulate on the lead plates of the battery.
