In order to make more profits, the black heart businesses often detain the original battery and replace it with low-cost high imitation battery. However, this kind of inferior mobile phone battery not only can not provide enough standby time for the mobile phone, but also can cause a lot of harm to the mobile phone itself. Sometimes it often crashes, or even destroys the motherboard! So how to identify the true and false of Nokia battery? It is enough to firmly grasp these five points.
Nokia BP-4L battery
Applicable models: Nokia N97, Nokia e71
At present, among the Nokia mobile phones, the Nokia N97 is the most popular. Let's take a look at the battery of the phone first. N97 uses BP-4L battery. The current market price is about 180 yuan. The high price also means huge profit margin. Many lawbreakers have come up with the idea of BP-4L high imitation battery. In fact, it is not difficult to identify this kind of battery. First of all, you can observe the small hole at the bottom of the battery. This hole is used for glue injection in the process of battery production, so it is hard to avoid some roughness. However, the holes of the high protection battery are completely disguised, which is much more neat by comparison.
In addition, it is also an important method to identify the authenticity of mobile phone by observing the contact of cell. Generally, the production process of high imitation battery is relatively backward, and the material and workmanship of the contact are far behind the original battery. The bionic contacts are generally thin and have little elasticity, which often leads to poor contact between the battery and the mobile phone, resulting in frequent crash. This kind of thin contact is very easy to deform, and the deformed contact can be distinguished visually.
When many netizens introduced their identification methods, they mentioned the square identification code on the back of the battery. The high imitation battery is generally fuzzy, while the pattern of the primary battery is very clear. Friends can combine several methods.
Nokia BL-5K battery
Applicable models: Nokia N86, Nokia N85
Nokia N86 is also a new flagship machine with high attention. This mobile phone uses BL-5K lithium battery. At present, the market price is about 100 yuan. Although it is not as high as BP-4L, it is also very attractive to produce high imitation battery of this model. It's hard to see the difference on the front of BL-5K. In contrast, the sticker of high imitation battery is very irregular.
However, there must be a difference between the fake battery and the original battery in the workmanship. It is not difficult to find that the contact of the high imitation battery is very thin, and the elasticity is very small when using sharp things.
Since the contacts have been deformed, we can be more sure that this battery must be a high imitation battery. Details determine success or failure, high imitation battery lost here.
Nokia BL-5F battery
Applicable models: Nokia n96, Nokia N95, Nokia n93i
Nokia n96 is equipped with BL-5F battery, which costs about 100 yuan. Many manufacturers of fake and inferior batteries also cherish this favorable opportunity.

The size of the original sticker is uniform, and the edges and corners are smooth.
What can you see from the picture above? In fact, it is a common method for Nokia mobile phone battery to identify the authenticity of mobile phone battery by observing cell contacts. In the picture above, despite the fine workmanship, the rough surface of the contact still reveals the mystery.

This high imitation bl-6f shows its flaws on the front of the battery. The front of the original battery has complete pits, while the high imitation battery is very simple to pull.
There is the same problem on the back of the battery. The high imitation battery not only has no groove design, but also has very rough cell contacts. If you use this kind of battery for a long time, it will damage the mobile phone to a certain extent.
