Battery loss refers to the battery after use, the actual capacity is small, lower than the nominal capacity. Battery loss is known to be a memory effect, but generally refers only to the memory effect of a laptop. The lithium-ion battery of the notebook has a design capacity, which can be seen on the tab of the battery, and some are expressed in milliamps (MAH), such as 4400mAh, some of which are said to Wah, such as 23Wh.
This capacity value is the theoretical value of the battery maximum capacity. With the use of the battery, the maximum value of the actual capacity will gradually shrink, and the reduced portion of this part is the loss of the battery. For example, the laptop battery theoretical capacity is 4400mAh.
After a period of use, the actual maximum capacity is now 4200mAh, then the battery loss is (4400-4200) /4400&mes ;100 %=4.5%. Notebook battery loss 1.
The battery itself is poor. 2. Using inferior charger 3.
High temperature or low temperature environment for a long time 4. Using the battery is a high load peripheral, unplugging. 5.
Excessive charge and discharge (battery use to 30% less than 3%). The circuit has protection, but occasionally happens. 6.
Incomplete charge and discharge (not used to use it, but want to use it, you want to charge it) 7. Long-term use of batteries in electromagnetic radiation (electrically conductive conductivity in the battery) 8. Long-term Using a battery (humid battery performance) WINDOWS8 and above can enter PowerCFG / BatteryReport to view battery usage and loss in the command prompt, and you can use hardware detection software (such as EVEREST, Master).
Sometimes. Laptop battery loss repair method 1. We can discharge the laptop battery directly, and then repair the laptop battery, but the degree of repair is also part, you can't complete the repair.
First unplug the power of the notebook, stop charging, then use the power amount only on the laptop, until the situation you can't boot, then charge the power supply, so repeatedly 2 times, then test the laptop battery The degree of loss is found to be reduced by the degree of loss. 2. Of course, you can also resume the discharge time of the laptop battery by notebook refresh program, and fix the loss of the notebook.
The refresh program of the notebook can be downloaded by the notebook, and then press and hold the F8 to enter the DOS system to perform battery refresh programs. The refresh program is executed is also a fixed use of the laptop's loss. 3.
Many lithium-ion batteries fail to fail to fail in the battery pack, this phenomenon cannot be prevented. Because the battery of each battery cannot be completely consistent, some of the same quality is slightly poorly aging, and the discharge curve of the overall (after series) is destroyed. Readers who are interested and capabilities can try to open the battery pack, with the help of the multimeter, can quickly find the damaged battery (voltage abnormal).
If the conditions are allowed, the qualified item can be replaced according to the corresponding parameters of the battery.
