At present, the Chinese market is flooded with many imported brand B products. The so-called B products are divided into "new B products" and "demolition":
1. The so-called "new B-product battery" can define the following two types:
1. The first type is due to the excessive mass production of batteries, plus the limitation of storage and sales cycles, resulting in a large inventory of products. Due to the long time no charge and discharge process, the electrical performance is greatly reduced compared with new products. However, from the comprehensive consideration of the difficulty of cost, recycling and processing, and the demand of the B product battery market, the battery cell factory will define this type of battery as a B product battery and sell it at the price of the B product battery. The process of assembling into a finished product is inherently a brand new B product battery.
2. The second type is due to the needs of different customers in the mass production of batteries, which require unified parameter pairing of the batteries. For example, if N batteries are combined, then the N batteries need to be unified voltage, Capacity and internal resistance are matched. For batteries that cannot be matched or exceed the range of these parameters, it is impossible to send letters to customers through normal channels, but it is also from the comprehensive consideration of cost, recovery and processing difficulties, and B products. According to the demand of the core market, the battery cell factory will also define this type of battery cell as a B product battery and sell it at the price of the B product battery. Since the battery cell is not assembled into a finished product, it inherently has a brand-new B product battery.
Remarks: The above two types of brand-new B-product batteries, the second type is relatively larger than the first type, but in any case, the quality and safety cannot be guaranteed, especially for the combined finished battery . As we all know, the combined battery requires strict pairing of the cells. There is no strict pairing. During the regular use, some of the cells will be protected in advance, which will not allow the entire finished battery to work efficiently. , If used improperly, it will also cause some safety accidents, such as explosion, fire, burning, etc. However, due to the flexible supply period and price of such batteries, they are widely welcomed by small PACK battery factories and cottage battery factories, mainly low-end customers and markets. In principle, battery companies will not guarantee the safety and quality of such batteries. Therefore, especially for high-end customers and high-end products, it is very important to choose a good battery cell and a formal battery supply platform!
2. The so-called "demolition of electrical cores" mainly refers to the fact that some domestic battery factories take into account the price problem and recycle foreign finished batteries, and remove and recycle internal batteries to combine into finished batteries. This type of cell is defined as a disassembled cell. In terms of appearance, the positive and negative caps have been spot-welded, and the appearance is not brand new, but after being assembled into a finished battery, users generally cannot distinguish it, but in terms of electrical performance, This type of battery has been used many times, so its cycle life is relatively far lower than that of the battery, and the user cannot distinguish it in the short period of time in the early period of use. Later, the customer complained that the battery took too long. Short and claimed.
Remarks: Since such batteries have been used, the quality and safety cannot be guaranteed. As batteries have been used for a long time, the cycle life cannot be guaranteed. After dismantling, there are also requirements for pairing. There is no strict pairing. During normal use, some batteries will be protected in advance, which will not allow the entire finished battery to work efficiently. If used Improper, it will also lead to some safety accidents, such as explosion, fire, burning, etc.; battery companies will not guarantee the safety and quality of such batteries. Shenzhen Dalixin Technology Co., Ltd. adopts imported batteries to develop and manufacture lithium-ion battery packs. All of them use the original A product batteries imported from formal channels including tax declaration, and resolutely put an end to deceive customers with shoddy charge or B product disassembled products.
