This is a relatively classic problem laptop battery is longer, often dissatisfied with the charge, or even show damage, it must be used in some simple tips: Whether you use the notebook lithium or nickel-metal hydride electric power, as much as possible to the basic use electricity to do after filling (capacity less than 5%), which is the best way to avoid the memory effect. In fact, the lithium-ion battery has some memory effect, but much smaller than the nickel-metal hydride batteries Bale. However, attention is needed to carry out charging as much as possible to avoid too long, the general control within 12 hours.
Battery life not by the length of the total use of time, but by the charge and discharge times to decide. If the battery will always be loaded to a notebook instead of taking down, then even if the machine shut down and remove AC power, the battery would not have imagined, as has been maintained, as when fully charged state. Notebook computer batteries due to the battery in the integrated control circuit, so even shut down your computer when power is power. As one connected to AC power, the battery will begin charging, when turned on or off the power, the battery will be charged and discharged repeatedly, affecting battery life.
To do this, use an external power supply when the AC is best to unplug the battery, or battery life if exposed to heat their impact on the state. If the long-term without the battery, please charge and discharge at least once a month to ensure that its activity. In the custody of the battery when there is a need for attention. At present, the vast majority of notebooks used in lithium-ion batteries do not use if a long time, often prone to the phenomenon of excessive discharge, may no longer be able to charge. In order to prevent over-discharge, can be in semi-charged state to save in a cool dry place, and then every six months, and then to half of its electricity charge state.
In addition, factors that affect battery life including the use of the environment temperature (below 30 ℃ proposed use), battery storage and battery temperature suffered shock size. The battery in use after a period of time will be aging, concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled, the capacity is lower than naturally . Batteries correction is an effective way to deal with aging batteries, a small number of laptop battery calibration software will be dedicated. If you do not have a dedicated discharge notebook software, you can follow the following steps:
● Disable the screen saver;
● In the Windows Power Management power scheme will be set to "always open";
● alarm at the tab will be "insufficient power warning" is set to 10%, the operation is set to "no action";
● will be "a serious power shortage alert," set to 3%, operating as a "waiting";
● the screen brightness to the maximum;
● confirmed closed all the windows, and save all the data from previous work;
● confirm battery charge in the 80 % or more, the unplug the power and all external devices.
Discharge after the notebook will automatically shut down after the power plug for laptop charging, this process can be repeated 2 to 3 times to let the battery continuous low current discharge, which discharge status in our daily use is not possible to achieve , the effects of the discharge and those dedicated basically the same software
