How to identify a Nokia phone and its battery

Look at the anti-counterfeiting label and code, sometimes the weight can also be weighed.

In addition, the original battery is much better than the others. **Generally 50-100. The practical life and use time are much longer.

Buy Scud's! The quality is no worse than the original! It's only 30 yuan!

Check whether it works or operates: * plus 0 plus 6 plus , that is, directly on the collection keyboard press *, ,0,6 and number Jian, and then the screen appears a channeled number, thank you mobile phone battery, and the number on the machine label comparison a ha, completely consistent with the description is licensed, otherwise it is a parallel import! Battery, it is better to buy an original battery of the same model, this is for the sake of safety, different models of batteries will sometimes be **!

Not to scare you!

The ground floor is too complicated:

Due to the increasing power of mobile phones and the increase in the use of our mobile phones, we should prepare spare batteries. Spare batteries can be a great solution, but beware of counterfeiting when buying. Counterfeit mobile phone batteries are very damaging to mobile phones, so how can you identify the authenticity of mobile phone batteries?

Here are a few ways to do it:

Look at the logo: The logo printing on the real battery board is very clear, while the counterfeit product is a copy of the plate printing, and the handwriting is blurred. Real panels"±"The polar symbols are made directly on the metal contacts, and the counterfeit ones are made on the plastic housing, and some do not have them at all"±"Sign.

Look at the process: the real battery board is welded by ultrasonic fusion, and the front and rear covers cannot be separated, and there are no obvious cracks. Counterfeit panels are mostly handmade, glued together, and with a little force, they will be cut in half.

Look at the safety performance: In order to protect the battery cell and the mobile phone, the regular mobile phone battery board is equipped with a temperature control switch, if the charging time is too long, the voltage is too high, the temperature rises sharply, and the battery board is hot, the power supply will be cut off in time to prevent the battery from leaking or **. The fake and shoddy battery boards do not have this device, but are only welded with an electric soldering iron, and even the non-rechargeable camera-specific small batteries are connected in series.

There should be four bright spots on the battery anti-counterfeiting logo.

Category 1: Ni-chromium batteries. It is the battery used in the era of mobile phones, which has a memory effect and has a small capacity, so it needs to be discharged and then charged, and it must be fully charged, otherwise it may cause permanent damage to the battery performance.

The second category: nickel-metal hydride batteries. Now most of the mobile phone battery, this kind of battery has no memory effect, the capacity is larger, can be charged at any time, but the initial 2-3 charging needs to be twice as long as the normal charging time, most of them require 8-14 hours of charging, in order to achieve the best performance of the battery.

Category III: Lithium polymer batteries. This kind of battery has no memory effect and has a large capacity. Charging can be done as you go, and the initial charge takes the same time as a normal charge.

Bought a fake? Buy a Scud or Pinsheng battery to compare.

Where did you buy it from? Is it licensed? Not a copycat???

BL4C is suitable for 6100 3108 5100 7270 7200 6108 6170 6260 2650 6131 6101 6125 and other machines, marked 760 mAh!

BL5C is suitable for N-Gage 1108, 1600 N71 N70 6681 6680 N72 N91 6030 6630 6230i 6670 1110 and other machines, marking from the earliest 850 to 900 to the current 970 mAh!

BL5B is suitable for 3220, 7260, 6020 3230 5140 6201 N90 N80 7360 and other machines, marked 760 820 mAh!

BL6C is suitable for QD and is labeled as 1070 mAh! BL5J for 5800XM and so on.

Note: 4C 5C 6C is the same size in length, but the thickness is different, 6C 5C 4C, that is, the machine with 6C can use 5C, 4C, the machine with 5C can be loaded with 4C, of course, some machines with 4C can also be loaded with 5C, there may be a rear shell can not be closed (because the battery is high, on top of the back shell) Some of the machines with standard 5C can be used with a larger capacity of 6C, for example, you can use 6C, and some players grind the NG back shell, Grind off the 6C bevel angle to make the power of NG even larger! The 6108 case comes with a pen and without a pen, with a pen using 4C, and without a pen using 5C!

BL and BP denote the type of battery, and both denote lithium batteries.

For example, the numbers in 5c and 6c indicate the difference in battery capacity, and the difference between 5 and 6 is 100 mAh.

5C and 5B represent the difference in battery length, and 5B is shorter than 5C. B C x both indicate the shape of the battery, and BL5Ca represents a lightweight version of BL5C, with a smaller capacity and thinner thickness, but the size remains the same.
