The notebook's lithium-ion battery has a design capacity, this data can be seen on the battery label, some are expressed in "mAh", such as "4400mAh", and some are expressed in "watt hour" Such as "23Wh". This capacity value is the theoretical value of the maximum capacity of the battery. With the use of the battery, the maximum value of the actual capacity will gradually shrink, and the reduced capacity is the loss of the battery. For example, the theoretical capacity of a laptop battery is 4400 mAh. After a period of use, the actual maximum capacity now becomes 4200 mAh, then the battery loss is (4400-4200) / 4400&TImes; 100% = 4.5%.
Battery loss refers to the fact that after the battery is used for a long time, the actual capacity becomes smaller and lower than the nominal capacity. Battery loss is commonly referred to as the memory effect, but generally refers only to the memory effect of a laptop.
1, the battery itself is of poor quality
2, use inferior charger
3, long time operation in high temperature or low temperature environment
4. The battery is connected to high-load peripherals, and the plugging and unplugging is not standardized.
5, excessive charge and discharge (the battery used to the remaining power is less than 3%). The circuit is protected, but it happens occasionally.
6, not fully charged and discharged (not used up and refill, but want to use it, want to charge it)
7. Long-term use of batteries in strong electromagnetic radiation (which will interfere with the conductivity of the metal inside the battery)
8. Use the battery under wet conditions for a long time (the wet battery will have lower performance)
Windows 8 and above can be found in the command prompt by typing "powercfg /BatteryReport" to check battery usage and loss. It can also be seen with hardware detection software (such as Everest, Master Lu), and sometimes false positives.
Laptop battery loss repair method
1, we can directly discharge the laptop battery, and then re-install it to repair the laptop battery, but the degree of repair is partial, can not be repaired. First unplug the notebook, stop charging, and then use up the remaining power on the laptop until it can not be turned on, then connect the power supply, so that the battery is used up and down twice, then the laptop battery is detected. The degree of loss, it is found that the degree of loss is reduced.
2, of course, you can also restore the laptop battery's discharge time through the notebook refresh program, repair the loss of the notebook. The notebook refresh program can be downloaded through the official website of the notebook corresponding brand, and then press and hold F8 to enter the DOS system to perform the battery refresh program. The completion of the refresh program is also a certain repair effect on the loss of the notebook.
3. Many lithium battery failures are caused by the failure of a certain battery cell in the battery pack. This phenomenon cannot be avoided. Because the cell properties of each cell are not completely consistent, some of the poor quality begins to age after a long time, and the overall (after series) discharge curve is destroyed. Readers with the interest and ability can try to open the battery pack, and with the help of the multimeter, you can quickly find the damaged battery (voltage abnormality). If the conditions permit, replace the qualified product according to the corresponding parameters of the battery core.
6.35MM Power+ Signal Power Connector
power connector is used in power module system. It can select the matching power + signal connector according to the need. The feature is that the number of power and signal contacts and the matching sequence can be selected arbitrarily while keeping the connector size and contact core number unchanged.
Plug (male) / socket (female) can be installed at 90 or 180 degrees. It supports mixed or independent combination of signal and power. The quantity range of power and signal is (2-16) pin and (12-128) pin respectively
Product features
High temperature resistant, glass fiber reinforced and flame retardant polyester is used as insulation material
Copper gold composite conductor with high conductivity is used, and the contact area of the conductor is plated with gold
It adopts shrapnel contact, which has the characteristics of integration, small volume, large current carrying capacity, soft plug-in, blind plug-in, self guidance and high dynamic contact reliability. This series of products can be interchanged with FCI's powerblade series and Tyco's multi-beam series
There are three sizes of center distance of power contact: 5.08mm, 6.35mm and 7.62mm
The length of power hole / signal pin can be selected in two sizes. The power rated current is 45A and the signal rated current is 2.5A
