In general, notebook battery cells use 10.8V or 11.1V, and a single battery cannot meet the requirements. Therefore, notebook batteries are battery packs in which a plurality of single cells are connected in series and in parallel. As for the 3300mAh, 4400mAh, etc., which are often seen in the battery case, it refers to the capacity of the battery. It indicates that the current can be used for one hour when discharging the battery. For example, a 4400mAh lithium battery can discharge at 4400mA for one hour. . So the larger the value, the better it will work.
?? Charge and discharge control and protection circuit as the name suggests is responsible for battery charge and discharge control and protection, it works like this, because the lithium battery will be slightly reduced when the charging process is very close to full, so the control circuit detects In this case, the battery is considered to be full, and the protection circuit also works to cut off the power supply to prevent overcharging; the voltage of the battery is basically stable when discharged, and only suddenly drops when the remaining power of the battery is low. When the control circuit detects this, it is considered that the battery power is used up and the protection circuit is notified to cut off the power supply to prevent the battery life from being shortened due to excessive discharge.
The internal structure of the laptop battery is actually quite simple, with a casing and a working circuit plus a battery pack.
This is the complete appearance of the laptop battery we usually see.
In general, the seams of the battery are glued together by the adhesive, so we can easily see the location of the bond, but basically this interface position, without strong tools, basically can not be opened.
After dismantling, you can see that more than 95% of the volume is a battery, plus a circuit board
Laptop batteries are basically battery packs
The battery is mainly the shell + circuit board + battery, the most important part is the battery, in fact, the most important part is the circuit, because the use of a battery itself is recorded in the circuit board. Repairing a battery, if it is just a simple replacement of the battery, it is useless, because the quality of the battery itself has always been recorded. Therefore, if you have to inquire about battery repair, you will find an unlocked word, in fact, reset the information about the battery recorded in the circuit board lock, such as resetting the number of times of charging, and the time of use, plus all the batteries The match will achieve the same duration as the new battery. These are the things to be discussed later in our maintenance section.
