Oops, in just a few months, the battery has failed?

Less than 1% of people in the world pay attention to us. You are a special person. Lead-acid battery failure may be caused by many reasons, such as vulcanization, loss of water, thermal runaway, active material shedding, plate softening, etc. Now Let me talk about vulcanization and water loss in detail. 1. The charging and discharging process of lead sulfide battery is the process of electrochemical reaction. When discharging, lead sulfate is generated, and lead sulfate is reduced to lead oxide when charging. This electrochemical reaction process is cyclically reversible under normal circumstances, but lead sulfate is a salt that is easy to crystallize. When the concentration of lead sulfate in the electrolytic solution of the battery is too high or the static idle time is too long, it will 'hold together' Clusters form small crystals. These small crystals attract the surrounding lead sulfate and form large inert crystals like a snowball. This breaks the original reversible cycle and causes the lead sulfate to be partially irreversible. The crystallized lead sulfate can no longer be reduced to lead oxide when it is charged, but it will also be adsorbed on the grid, resulting in a decrease in the working area of u200bu200bthe grid and a decrease in the capacity of the lead-acid battery. This phenomenon is called vulcanization. 2. One of the most basic principles of the loss of water sealed lead-acid battery is that after the positive plate oxygen evolution, the oxygen directly goes to the negative plate and the hydrogen evolution of the negative plate is reduced to water. The parameter for assessing the technical index of the lead-acid battery is called'sealing reaction efficiency' This phenomenon is called the'oxygen cycle'. In this way, the water loss of the lead-acid battery is very small, and the maintenance-free is realized, that is, no water is added. High-current discharge and long-term unused batteries reduce the ability of the negative plate to circulate oxygen, causing the battery to lose water, and the battery after losing water leaves the sulfuric acid component, which is equivalent to further increasing the specific gravity of sulfuric acid, thus making lead acid Batteries are more susceptible to vulcanization. Therefore, the vulcanization of lead-acid batteries aggravates the loss of water, and the loss of water intensifies the vulcanization. Note: In the final analysis, the main factors for battery failure are human and self. 1. Regarding human factors, when we are using batteries, we need to maintain them more. 2. Regarding our own factors, we must be cautious when choosing batteries, and try to choose high-quality, well-reputed brand batteries, such as batteries. The battery quality is very good, the service is also good, and the sales, customer service, technical support, maintenance and other aspects are well established, which can provide consumers with better after-sales service.
