What is the future market of battery repair instrument?

Generally speaking, the market of battery maintenance instrument is good, but the market of battery maintenance instrument is more and more chaotic because of the deception of many manufacturers who pretend to obtain national patents, such as Beijing Shouda, Beijing Guo Da, Beijing Zhong Da Tongchuang and Beijing Zhongke Jing Rui. These fake companies claim to have obtained national patents, but if they go there for inspection, Their patents were either bought from people's old patents or fabricated on purpose, and their own patent information could not be found on China National Intellectual Property Administration's website. As a victim, I have the right to share my experience with customers who need to buy a battery repair instrument. As for which company in Beijing really has a national patent, through my audit, I think the plasma battery repair instrument produced by Beijing Zhongke Ruifeng Technology Co., Ltd. is not bad, and it is a manufacturer that really has a national patent in the industry at present. The author only looks at the problem from the perspective of a third party. You can check the patent through China National Intellectual Property Administration website!
