IBM ThinkPad 40Y6797 Laptop Battery

As this IBM ThinkPad 40Y6797 Laptop Battery, it’s lithium battery. It’s used for half a year. But it always shows that the battery is charged full after two or three hours. Generally, lithium battery has slight memory effect. How to prevent laptop battery from aging? Here offers you some tips about laptop battery.

After long time working, it often insufficient charges, or even shows damage. Whether your laptop uses lithium or nickel-electro catalytic, it is the best way to avoid the memory effect to use up the laptop keyboard . In fact, the lithium-ion battery has some memory effect. The general charging time is within 12 hours. As it’s known that battery life depends on the charge and discharge times. That is to say, the battery will be charged and discharged repeatedly once you turn on and off the laptop. Battery will be used after a period of time aging, specific performance is the internal resistance become larger when the voltage across the charge up too fast. So Battery calibration is an effective way to deal with aging batteries, a small number of notebook battery calibration software will be dedicated. If your laptop does not discharge specific software, you can follow these steps:

● Disable the screen saver;

● In the Windows Power Management power scheme will be set to “always open”;

● In the Alert 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 “pending”;

● the screen brightness to the maximum;

● sure all the windows closed, and save all the data before work;

● Check that the battery charge after more than 80%, unplug the power and all external devices.

After the discharge, the notebook will automatically shut down. Then plug for laptop charging. This process can be repeated 2 to 3 times aiming at continuous low current discharge. And its effect is similar to that of discharge software. My friend’s ThinkPadhas revived again. As time passed by, the battery will get older and older, even retired. So try to take good care of it while  it’s pretty new.
