The battery has chemical substances with oxidizing properties inside, but the battery core inside the laptop battery case is sealed with chemical substances inside the battery core. As long as the battery core is not damaged, there will be no leakage of foreign materials. The laptop battery can be divided into three parts: the case, the battery pack and the protection board.
Laptop battery case:
The outer casing of the notebook battery can be divided into: snap type, ultrasonic bond type and glue bond type according to different bonding methods.
Laptop battery cell group <br> cell group, i.e. the batteries in parallel, in series combination together. According to the parallel and series combination, it can be divided into: 2 and 3 strings (most common), 2 and 4 strings, 2 and 2 strings, 3 and 3 strings, and 3 and 4 strings (relatively rare).
Note: 2 and 3 strings means that the two batteries are connected in parallel, and then the three groups of batteries connected in parallel are connected in series. 2 and 3 strings of a total of 6 batteries, which is what we usually say 6-cell lithium battery.
<br> laptop battery protection board laptop battery protection board, which is a protocol based SMB1.1 circuit board having a power management and charge-discharge management function.
The protection board is a circuit board based on the SMB1.1 protocol, and has three chips on it: a battery metering management chip, a charge and discharge management chip, and a serial EEPROM memory chip.
Laptop battery protection board <br> The front of the protection board is equipped with a laptop battery metering management chip and a charge and discharge management chip. The battery protection board has a serial EEPROM memory chip on the back.
Decrypting and unlocking the laptop battery protection board are two different jobs. To put it simply, the battery management system can only be decrypted before the battery management system is unlocked. Only the battery management system can be unlocked to change the battery parameters and usage information. If you only change the battery and do not unlock it, you will not be able to achieve satisfactory results (for example, the battery can only be charged to the last full charge capacity recorded, and the battery management information will show the number of times used before the repair).
