The battery does not need to be ignorant? Professionals say the battery also has a shelf life.

On October 20th, Mr. Li told the reporter that the 4 Nanfu batteries that he purchased were placed for two years. When they were taken out, they were out of power and the packaging was intact. Mr. Li carefully looked at the outer packaging and found that the battery had expired for 8 months. "I only know that the food has a shelf life, and I have never heard of the battery and have a shelf life." Mr. Li said.

The reporter learned from the Xixia District Industrial and Commercial Bureau that the battery reacts chemically through the positive and negative electrodes inside. The positive and negative materials are chemically reacted at all times due to the presence of trace amounts of impurity elements, which consume active materials and have long battery storage time. The active material will decrease, the capacity will drop, and there will be weak or no electricity that we see. In general, the shelf life of ordinary batteries is 2 years, and the shelf life of alkaline batteries is 3 years, but many consumers do not understand this. The staff reminded consumers to look at the production date and shelf life of the battery when purchasing the battery, try to use the battery produced recently, and do not purchase batteries without production date and shelf life.

NCVM Series-Metal High Speed CNC Planing Machine

A metal high speed CNC planing machine is a type of industrial equipment used for machining metal surfaces. It is designed to remove material from a workpiece by using a cutting tool that moves back and forth in a linear motion, creating a smooth and even surface. The CNC (Computer Numerical Control) system allows for precise control of the cutting tool's movements, ensuring accuracy and consistency in the finished product. The high speed capability of the machine enables it to operate at faster speeds than traditional planing machines, increasing productivity and efficiency in the manufacturing process.
