"The more the lithium-ion battery discharges, the greater the loss of the battery," said Tom Hartley, a professor of electronics engineering at NASA, which Akron the space agency's research to extend battery life, saying, "The more you charge the battery, the more the battery will wear out." Lithium batteries are best placed in the middle of electricity, which is the longest battery life. ”
If the long-term use of external power supply for the notebook computer, or battery power has more than 80%, immediately remove the laptop battery, the usual charge does not need to fill the battery, charging to about 80% can be; The charge is to be charged before it drops to 20%;
You should disconnect the power cord (including the USB connector with the charging function) immediately when the electricity is recharged. It will damage the battery, always charge, remember, but do not have to fill the battery, whether it is for laptops or mobile phones, must not let the battery run out, the so-called extremes are the truth.
If you want to travel, fill the battery, but please remember that when the conditions allow for electrical charging at any time, in order to battery life, must not wait until the battery dry, now people have a lot of electronic equipment, a large part of the use of lithium batteries, to ensure that the battery life is very practical. After all, the battery is scrapped to recycle, otherwise it will cause serious pollution to the environment.
