Uninterruptible power is crucial for all types of applications. For the rail industry, operators depend on long life, onboard batteries designed with reliability, robustness and safety to ensure continual operation of emergency backup systems. Additionally, opportunities to eliminate sudden failure and enhance public safety, via signaling systems at places like level crossings for example, are cri...

Power outages are one of telecom companies’ worst nightmares, as they lead to loss of revenue, customers, image, and so on. In response, internet and telephone providers have expressed a keen interest in having a power backup system. There is a wide choice for telecom companies regarding which backup system they want such as diesel and natural gas generators, fuel cells and batteries. Ty...

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...
