During the long-cycle cycle, the reversible capacity of the lithium-ion battery will continue to decrease due to the reduction of active materials, the precipitation of metal lithium, the continuous consumption of electrolyte, the increase of internal resistance and thermal runaway. Among them, the lithium evolution phenomenon of the graphite negative electrode is the most important cause of batte...

Installation and servicing of the 12V VRLA battery should only be performed and supervised by personnel knowledgeable of lead acid batteries and required personal and equipment safety precautions. Keep unauthorized personnel away from the batteries and installation activity. Electrical Hazards Battery systems present a risk of electrical shock and high short circuit currents. The following precaut...

What are the effects of temperature on the performance of lead-acid batteries? From the chemical reaction equation of lead-acid batteries, PbO2 is on the positive plate, and Pb is on the negative plate. The electrical and physical properties of these two substances vary very little with temperature, so it can be said that the temperature effect of the discharge performance of lead-acid batteries i...

1. Meaning of maintenance-free battery The main advantage of the valve-controlled lead-acid battery is that the oxygen generated on the positive plate during charging is reduced to water on the negative plate through the recombination reaction, and water does not need to be added during the specified floating life period when used, so it is also called maintenance-free lead-acid battery. It can be...

1. Prevention of Electrochemical Corrosion (The Most Critical Reason)   Physical Principle: In humid environments, metal conductors carrying a positive voltage (positive pole) are more likely to attract negative ions from the air, leading to electrochemical corrosion and causing cables and terminals to gradually rust and break.   System Design: If the positive terminal of the power suppl...

In modern data centers, uninterrupted power is critical. Backup power systems must be reliable, cost-effective, and capable of delivering instant energy when utility power fails. While lithium technologies have gained attention in recent years, lead-acid batteries—especially VRLA AGM batteries—continue to play a vital role in data center UPS applications worldwide. With decades of prov...

Uninterruptible Power Supply (UPS) systems are essential for providing backup power during outages or fluctuations, ensuring that critical devices remain operational. From protecting servers in data centers to keeping life‑saving medical equipment running, UPS systems are vital in various industries. Among the most widely used energy storage technologies in UPS systems are lead‑acid batteries. Kno...
