Battery Use and Maintenance Tips affect laptop battery standby time is the key. To improve endurance capacity, focusing on battery maintenance is essential. 1 using a laptop computer to read carefully before using the manual battery maintenance part of it; 2 The first charge, you should continuously charge the battery to full (usually 12 hours or more), and run 3 times to do so fully awakened new battery; 3 If prolonged use of external power supply, best to remove the battery. Many of my friends did not notice this issue, remove the battery without external power supply not only affect the battery life, notebook computer also allows the heat burden becomes heavier, shorter battery life; 4 periodically charge and discharge. Even without the memory effect of lithium-ion battery there is a certain inertia effects, for a long time not to use lithium-ion loss of activity, need to re-activate. Therefore, if time does not use a computer or find that the battery charge and discharge time shorter, should be done 2-3 times a run-in, usually at least once a month. 5 best to turn off when charging laptop, the battery can be fully charged, do not unplug the power drop in the charge. Charge off charge than the power to shorten the charging time more than 30%, and can extend battery life. Best finish in 30 minutes of charging before use. 6 Li-ion battery charge and discharge is generally not more than 1000 times on one charge, it will shorten the time of life. Suggest that you use an external power supply, if you use half-way multiple plug built-in battery power and the laptop did not pull out, will make a great battery life shortened because every time access is equivalent to an external power supply charge the battery once.
