3. If the prolonged use of external power, it is best to remove the battery. Many friends did not notice this issue, remove the battery without external power supply not only affect the pool of life, also makes laptop heat burden became even heavier, shortening the life of notebook computers;
4. Regularly charge and discharge. Even without the memory effect of lithium ion batteries there is a certain inertia effect for a long time without loss of activity of lithium ion would need to re-activate. Therefore, if a long time (three weeks or longer) without using a computer or find that the battery charge and discharge time shorter, should be fully discharged before charging the battery, usually at least a month a full charge and discharge 1.
