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.
All rechargeable batteries degrade over time. Lead acid and sealed lead acid batteries are no exception. The question is, what exactly happens that causes lead acid batteries to die? This article assumes you have an understanding of the internal structure and make up of lead acid batteries.
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.
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.
Just because a lead acid battery can no longer power a specific device, does not mean that there is no energy left in the battery. A car battery that won’t start the engine, still has the potential to provide plenty of fireworks should you short the terminals.
In the case of a lead-acid battery, the chemical reaction involves the conversion of lead and lead dioxide electrodes into lead sulfate and water. The sulfuric acid electrolyte in the battery provides the medium for the transfer of electrons between the electrodes, resulting in the generation of electrical energy.
