Precautions for using the laptop battery

（1）Whether the new laptop battery needs to be activated

In fact, the activation of the battery in the factory should have been completed, the laptop battery shipped with a little power is to avoid the natural loss of damage to the battery. The activation of the battery should be carried out in the absence of protection circuit, the lithium battery itself with a protection circuit, the design of the circuit block is designed to avoid excessive charge and discharge of the battery, the general battery is fully charged, the charge indicator Out of the moment, the battery is not charging, then this time you plug in the charger then charging it does not make any sense. We can see from the status of the battery whether the battery is charging, there is a simple way to determine whether the battery is charging, the battery will emit a certain amount of heat when charging, when the battery is full after one hour (charger Power plug not unplugged), you go to touch the battery, this time you will find the battery is at normal temperature, it is because the battery is not charging at this time, of course, there will be no heat generated.

 （2）How to charge properly

Regardless of the notebook using lithium batteries or nickel-metal hydride batteries, these batteries have a memory effect, nickel-metal hydride batteries have a significant memory effect, lithium also memory effect, but its memory effect relative to NiMH smaller. We have heard of the so-called lithium battery has no memory effect, it is only some js exaggerated, the purpose is to guide consumers in the wrong. Since the battery lithium has a memory effect, then when charging should try to run out of electricity and then recharge, do not just want to go to recharge when charging, so although easy to use, but will shorten the battery life. However, we also have absolutely no need to wait for electricity to recharge completely, which is too troublesome. Although this battery is protected under the protection of the circuit will not not damage the battery, but there is nothing particularly necessary. In fact, when the charge is less than 3% of the charge on it, the memory effect is still an objective reality, but compared to the natural loss, it is nothing.

(3) the need to unplug the battery when using an external power supply

In fact, it depends on when you use an external power supply is not needed to charge the battery, the number of battery charging is directly related to the life, under normal circumstances, the number of lithium battery charge and discharge is fixed, the number of charges is generally only about 500 times, up to No more than 800 times. Each time we charge the battery, correspondingly, it reduces the number of recharging times. However, many notebook manufacturers have taken into account the vulnerability of the battery, an increase of the battery protection technology, does not meet certain conditions will not be charged. Even so, when you use the computer for a long time using an external power supply is also recommended that you unplug the battery, because high temperature is also one of the battery's nemesis, the laptop will produce a certain amount of heat when used, which is very harmful to the battery. Of course, if you are not sure about your own battery, I still recommend that you unplug your laptop battery and then use an external power supply.
