Fault analysis of the reason for the continuous alarm of the computer backup power UPS. The backup power supply UPS machine itself has a certain level of noise, which is mostly caused by the UPS being fully loaded or overloaded, resulting in some light "squeaking" sounds. If it is an alarm...

With the promotion of energy conservation and environmental protection in society, more and more environmentally friendly products are being applied to the market. In the battery industry, ternary lithium batteries quickly occupied the market with numerous advantages and gradually replaced tradition...

How can we find products that meet the specifications in Linlin's various lithium batteries? We only have to arm our own brains!Today, we will teach you a lesson about lithium batteries together. We hope that after learning, you can arm yourself and buy legitimate, safe, and long-lasting lithium...

The number of cycles and charging cycle of lithium-ion batteries for mobile phones are closely related. The so-called lithium-ion battery cycle charging refers to a complete charging and discharging cycle, so the number of cycles is actually a calculation method of the charging cycle. When the lithi...

Many people use maintenance free lead-acid batteries, thinking that the battery is solid and can be inverted or placed on the side, but this practice is incorrect.Although the separator of maintenance free lead-acid batteries can absorb and store electrolyte without flowing, thus preventing acid ove...

What is the reason for the heating of lithium battery pack during charging? Is it normal for lithium iron phosphate battery packs to generate heat during charging? What is the reason behind this? The heating of a lithium battery pack during charging can be simply explained as the generation of heat...

Under the same capacitance conditions, a lithium battery with a higher energy ratio is definitely lighter in weight;The best one currently available is the Panasonic 18650 lithium battery, which has an energy ratio of over 150Wh/kg;Generally, the energy ratio of domestically produced lithium batteri...

The hazards of waste batteries mainly focus on the small amounts of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various pathways and accumulate for a long time, causing damage to the nervous system, hematopoietic function,...

The active material on the positive plate of lead-acid batteries is lead dioxide, and the active material on the plates is sponge like pure lead. The electrolyte is a certain concentration of sulfuric acid solution, and the electromotive force between the plates is about 2V.The active material on th...

Reject the positive and negative electrode materials of the battery. The voltage of common positive electrode materials such as lithium cobalt oxide and lithium manganese oxide is around 3.7, while that of lithium iron phosphate is around 3.2. The common negative electrode material graphite has a vo...
