Battery Failure Mode: Negative Plate Sulfation
When a lead-acid battery is left to self-discharge (in storage or installed but seldomly used) or is exposed to excess and repeated high-rate charging (such as is the case with Start-stop vehicles), a point can be reached where the reaction at the negative plate that should convert the lead back to active material (PbSO4 back to Pb) can not accommodate all of the charging currents.

6 FAQs about [Lead-acid battery floating plate]
What is a lead battery plate?
The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates. Overall battery capacity is increased by adding additional pairs of plates. A pure lead grid structure would not be able to support the above framework vertically.
What happens if a lead-acid battery is continuously floating?
Continuous floating at 2.05v per cell will destroy a lead-acid battery due to sulfidation. Float charging is a compromise between what the negative plates needs to keep it charged and prevent sulfidation and positive plate which will oxidizes plate grid causing high internal equivalent series resistance.
How does a lead acid battery work?
Lead acid battery manufacturers apply this paste to a frame or grid structure that mechanically supports it. The electrolyte is then free to enter all the tiny holes in the sponge, thereby increasing the effective capacity of the battery. The negative and positive lead battery plates conduct the energy during charging and discharging.
Why is a lead acid battery a little less?
It’s always a little bit less due to losses and internal resistance. A Lead-Acid battery consists of two primary components: lead dioxide (PbO2) as the positive plate and sponge lead (Pb) as the negative plate. Both od those electrodes are submerged in an electrolyte solution of sulfuric acid (H2SO4).
How do you make a lead acid battery?
The most common approach nowadays involves turning the active material into a paste, with the appearance of a sponge full of tiny holes. Lead acid battery manufacturers apply this paste to a frame or grid structure that mechanically supports it.
Which type of lead cell should be used for float and shallow cycling?
Lead-calcium and pure lead cells are recommended for float and shallow cycling service where average discharge depth is less than 20%. Pure lead alloy cell types are used when very low charged stand loss is a requirement in the application and occasional deep cycles are expected. Negative plates in all lead-acid cells are the flat pasted type.
