The phenomenon called "sulfation" (or "sulfatation") has plagued battery engineers for many years, and is still a major cause of failure of lead–acid batteries. The term "sulfation" described the condition of a battery plate, in which highly crystalline lead sulfate has formed in an practically irreversible manner. This type of ...
Effective repair of the battery can maximize the utilization of the battery and reduce the waste of resources. At the same time, when using lead-acid batteries, we should master the correct use methods and skills to avoid failure caused by misoperation.
Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
The crystallized lead sulfate not only does not participate in the reaction, but also adsorbs on the surface of the electrode plate, which increases the internal resistance of the battery and affects the charge and discharge performance of the battery and the battery capacity3.
All lead-acid batteries will naturally self-discharge, which can result in a loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery’s electrolyte and the chemistry of the plates.
Repairable failures without timely intervention will cause irreparable failures of the battery. For example, in the case of overcharging, high-concentration sulfuric acid will severely corrode the electrode plate, and even causing it to deform and permanently fail.
The Internal Structure of Lead-acid Batteries The internal structure of a lead-acid battery is mainly composed of positive and negative plates, electrolyte, separators, etc., as shown in Figure 1.

In flooded lead–acid batteries, roughly 85% of all failures are related to grid corrosion, while in valve-regulated lead–acid batteries, grid corrosion is the cause of failure in about 60% of cases. This is a problem that develops over time and it typically affects batteries that are close to end of life. In other words, if the preventable causes of failure are eliminated, then …

The lifespan of a 12V lead acid battery varies, but on average, flooded lead-acid batteries and sealed lead-acid batteries last about 3 to 5 years. Sealed deep cycle batteries may have a longer lifespan of around six years. By following proper maintenance practices, such as regular charging and avoiding deep discharges, the longevity of a 12V lead acid battery can …
Acid is heavier than water and is fundamental to a lead-acid battery''s electrochemical charge and discharge process. Acid stratification happens when the heavier acid in the battery''s electrolyte separates from the water and assembles at the bottom of the battery''s cell, creating an area of very high specific gravity electrolyte.
