First, the cause of battery damage
Laptop battery used for a long time, often charged with electricity, or even show that the battery has been damaged, the specific performance is the internal resistance, in charge at both ends of the voltage rise relatively fast. In this way the charging control line is judged as already full, and the capacity is naturally decl

MIT scientists have developed a revolutionary cell phone battery that can be recharged in just 10 seconds.
New batteries are 100 times times more charged than conventional batteries, scientists say, and can be used on mobile phones, laptops, ipods, digital cameras and cameras in 2-3 years. In addition, the same technology can greatly shorten the charging time of electric vehicles, can
in the past seven years, the mobile phone has completed from the function to the Intelligent Machine transformation, the role of mobile phones in life is becoming more and more important. However, the rapid development of mobile phones, performance and other aspects have been rapid development, but battery technology has been slow development, which has become a constraint on mobile phones further development of the important reason. history and curre
Generally speaking, lithium battery has high storage energy density, low self-discharge rate and high safety, so it is widely used in mobile devices all over the world. However, the use of lithium batteries need to pay attention to a number of safety issues to prevent the occurrence of dangerous, users need to pay attention to the storage and proper use of batteries.
Use the Samsung licensed USB power adapter,
People to sum up some experience
First, do not care too much, with the use of charge, but it is recommended that each month to have a full charge and discharge process, that is, when the red line to recharge the process.Second, lithium battery normal charging method: at any time to charge, and can stop charging at any time, do not have scruples. This is the important advantage of lithium batteries----no memory effect of the decision, please face this

How do we perform a regular discharge of a notebook that does not have a discharge function? After a lot of experiments, we finally recommend that you:
Start the computer (press F2, F12, or delete (a slightly different type of entry) into the BIOS, and then on the keyboard, adjust the brightness of the display to the minimum.
Let it run out of battery power until it shuts down automatically. This is a low current, uniform discharge, which can be rep
Does the Win8 system find that the battery has no power during important conferences or long flights? Even with the use of new technologies, a single-charging laptop or tablet can only last for so long. This technique is used to make full use of power.
