Different types of battery performance of different:

Notebook computers are now widely used lithium-ion battery(Or similar products), But so long ago notebook computers, A4-based notebook computer under the premise of the temporary use of nickel-metal hydride batteries are also used. And then forward until the mid-Nineties, using anickel-cadmium batteries.

First, look at operating instructions, to confirm what kind of battery is used. If there is no manual you can view the battery manufacturer's home page specification.

Nickel-metal hydride batteries and nickel-cadmium batteries biggest problem is the "memory effect", if the battery has not run out on the charge (half-way charge), then next time you use the battery when the charge used in the beginning there is no electricity in that place. If the continuous cycle of this process, the battery life will be shorter and shorter.

Although the Ni-MH battery memory effect is smaller than nickel-cadmium batteries, but repeated half-way charging also the reasons of shorten the life of. So please try to recharge after the battery fully utilized.

Lithium-ion battery without memory effect, so even a half-way off and charging is also no problem.

The ways of extend battery life

Although the lithium-ion battery without memory effect, but using methods greatly affect the life span. The use of lithium-ion battery Please note the following points:

Full power state not to use AC power supply-driven.

Compared with no full power, full power state more easily aging. In particular, use of AC electric power-driven when it is full ,it will bring a heavy burden for battery. It also increases the amount of heat and  further accelerate the batteries aging speed.

Therefore, when you use of a laptop computersthe temporary, a good idea  is to use battery power first. once filled with electricity,

Manufacturer recommends remove the battery when you use of AC power (if remove the battery, we must pay attention to unplug the occurrence of accidents such as power outages or cable, it will losing the not keep data).

Use power-saving features

The factors that affect the battery life is the charge and discharge times. In order to minimize the frequency of recharging, we can use saving function that laptop computers itself power (when using battery-powered, dimming the screen brightness, reducing CPU speed to reduce power consumption).

By the same token, the battery there is electricity, it is best not to charge the battery untill fully utilized.

Fully discharge once every other months,

Another technique is fully discharged once per mounth or a few months. A specific approach is to using all the while and when  the battery¡¯s power is zero stop using it, then connect AC adapter, and do not use personal computers, at a stretch to full power.

Some personal computers have a "battery discharge (Battery Refresh) function." you can try using the battery discharge feature If you  think that the battery not easy to use,.

A long time when not in use, unplug the AC adapter.

More than eight hours or more when not in use, in order not to burden the battery, please unplug the AC adapter. Also, if more than a month when not in use, please remove the battery from the machine and placed in the shade.
