How to distinguish whether the electric vehicle battery is original?

How to tell if the electric vehicle battery is original? The first measure: look at the appearance. The appearance of the new battery is smooth and clean. The surface of the refurbished battery has been polished to eliminate the original mark, repainted and marked and dated. A closer look reveals the marks and date labels that were polished off the original battery. The second trick: Look at the terminal refurbishment battery. There is solder residue in the terminal hole of the battery. Even if it is cleaned, there will be traces of polishing, and the new battery will be bright. Some refurbished batteries have replaced the terminals, but the positive and negative electrodes are marked with uneven color paint, which shows signs of refilling. The third trick: look at the anti-counterfeiting label and QR code of the battery. Generally speaking, most brands of electric vehicle batteries will have an anti-counterfeiting label attached to the docking part of the battery shell when they leave the factory. Therefore, when purchasing, pay attention to see if the anti-counterfeiting label is well pasted, and if necessary, you can also scratch off the anti-counterfeiting label password coating to verify its authenticity. The fourth measure: Recognize the brand and look at the trademark. When buying a battery, you can also carefully observe the trademark of the battery shell to see if the production process is delicate. Generally speaking, the refurbished businesses do not have professional trademark spraying and shell processing technology, and the authenticity of the battery can often be clearly seen from the shape of the trademark. Therefore, everyone must choose a high-quality battery manufacturer with a good reputation. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
