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.

Aging mechanisms and service life of lead–acid batteries
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 ...

Lead–Acid Batteries
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 …
