The authenticity of Dayi batteries depends on the anti-counterfeiting label. Generally speaking, most brands of electric vehicle batteries will have anti-counterfeiting labels affixed to the joints of the battery shells when they leave the factory. Therefore, when purchasing, pay attention to see whether the anti-counterfeiting label is well pasted. If necessary, you can also scratch off the password coating of the anti-counterfeiting label to verify the authenticity. Finally, pay attention to the production date printed on the battery.
Generally, after genuine Dayi batteries leave the factory, they come with two things, a certificate of quality and a warranty card. These two can be said to be the identity certificates of new factory batteries, especially the warranty card. It is also an effective certificate for seeking solutions from the merchant when there is a problem with the product. It can be said that batteries without a warranty card must still be refurbished.
Battery identification skills
When purchasing a battery, you can also carefully observe the trademark on the battery casing to see if the manufacturing process is exquisite. Generally speaking, refurbished businesses do not have professional trademark spraying and casing processing technology. The authenticity of the battery can often be clearly seen from the shape of the trademark.
Generally speaking, the new battery casing is very smooth. If you find that the casing is uneven, you should pay attention. To check whether the casing is flat, you can find a table or floor with a level surface and place each side of the battery face down. If the battery can rotate, it means the battery is uneven, which means the battery should be an old battery.
