When you buy a Nokia mobile phone, you must distinguish between genuine and fake products. Let me talk about the identification method of the battery first. First of all, from the manufacturer's point of view, there are several Nokia battery manufacturers:
1: Sanyo Energy Beijing Co., Ltd. (the most)
2: Zhuhai Panasonic (more)
3: Dongguan Samsung. Among them, Shenzhen Sanyo Huaqiang Energy has the most.
From the perspective of battery packaging again:
The packaging paper of Nokia's original batteries is beautifully printed, and now the new batteries will be printed with the model, capacity and production date. Take BL-5C battery as an example. Its capacity is 97mAh and 9mAh. Any other capacity label must be a fake.
The copper of the positive and negative metal interfaces of Nokia's original battery is matte. If someone's battery's positive and negative metal interfaces are bright and reflective, it is counterfeit.
The wrapping next to the positive and negative metal interfaces of Nokia original battery is soft rubber, which can be felt with your nails. This is designed to prevent the battery from short-circuiting after water enters. If you press it hard with your nails, it is counterfeit.
Nokia's original batteries also have anti-counterfeiting labels, but with the development of science and technology, some counterfeit batteries also have similar anti-counterfeiting labels. Let me talk about the identification method here. It is easiest to break through from the handshake pattern inside the anti-counterfeiting label. The handshake pattern in the real label will change its position when you look at it from different angles, but the counterfeit one will not.
Finally, from the price point of view:
The cost of a good battery can be divided into two parts: the battery core and the protection circuit. At present, the best batteries in the world are made in Japan, among which Sanyo is the most, and its cost is related to the capacity, generally around 16-2. The main cost of protecting the circuit board is to protect the chip, which is still made in Japan as the best, followed by Taiwan Province, with a cost of 2-5, so the cost of a high-quality battery is around 2-25. If the price of the battery you buy is lower than it, it will definitely not be a good battery. Take Nokia BL-5C battery as an example: in Gome, a large retailer, bulk purchases are made through formal channels. These batteries are all genuine boxed, and the price is 9 or 12 (I can't remember). I don't know the price of the specialty store, but I personally think it should be expensive. I suggest that you don't buy it there. In Huaqiang North, you get it through informal channels (I personally think they replace the batteries on the original machine with high imitation electricity).
