Want laptop battery life extension? This is right

Monday Xiaobian pushed the "short-lived computer? That's why you didn't use it. Many small friends want to ask how the laptop battery should be used in order to extend its life, or how to use it to avoid unexpected failures. Today Xiaobian has answered it together, hoping to help everyone.

Lithium battery with charge

Before clarifying this point, small partners should remember two things: First, there is no so-called activation of lithium batteries; second, lithium batteries have no memory effect. Therefore, lithium batteries used in notebooks (whether lithium ion or lithium polymer) are basically used with the charge.

In fact, what is directly related to the life of a lithium battery is the number of cycles, not the number of charges. The number of cycles refers to a charge cycle, which is simply a cycle in which a lithium battery is full to empty and then empty. For example, your laptop uses 50% of the electricity today, then charges it to 100%, and then uses the battery to recharge 50% of it again, so that each time you charge 50% of the electricity, it counts as a cycle instead of two. The number of secondary charges. At present, the lifetime of lithium battery is generally 300 to 500 cycles, so if the battery is used normally, it can be used for a long time.

Do not repeat 90% to 100% charge

Since there is no memory effect, how can you charge it easily? Of course not, there are two pitfalls to avoid. The first one is overcharged. The so-called overshoot is that only a few percent of the power is used to wait for it to be full (obsessive-compulsive disorderers, knock on the blackboard). It is always charged in this interval, and the battery is very depleted. , especially the 90% ~ 100% of this power range, has been plugged in the power of the laptop's friends often see their notebook for a variety of reasons, a slight loss of power, this situation do not blindly charge, take a while to remove The power supply is battery-operated and can be used up to less than 80% and then fully recharged (preferably to about 50%).

The other is over-discharge, such as always using less than 5% of the battery, this is actually not a big relationship with the lithium battery itself, mainly due to the notebook's power management chip. If you encounter low battery voltage, naturally, the battery management chip may think that the battery is faulty and then lock the battery. As a result, the battery will not be charged. This is also the reason why the operating system has to lower the frequency of the notebook after 10% and forcefully shut down the 5% or so. Of course, it is better to keep the battery power at 20% or more, so it is relatively easy.

Lithium battery is afraid of heat collision

Many bulging batteries, in addition to notebook design flaws (very rarely occur), more often because of external factors. In general, the bulging battery is only encountered in two situations: one is collision and the other is overheating. Therefore, it is very important for the notebook to have a good working environment. For example, do not make excessive collisions. There is also a good ventilation environment, such as using a notebook on a quilt. Xiao Bian strongly opposes it.

How is the notebook power-off?

Some laptops will also have a unique phenomenon: The battery is powered down when the power is used! There are two types of this happening. The first type is the cottage power supply that uses a third-party virtual standard. When the system is fully loaded, it will naturally “stealing” the battery. The second type will be more rampant, mainly in the game type. In laptops, the standard power supply is not enough to support the system running at full load for a long time. It is also the same as stealing power to the battery. This is why some game notebook users are required to additionally have a more powerful power supply.

In the end, Xiao Bian said that the basic life of a battery is generally the same as it was in three or five years. It is very difficult to maintain a good condition for a long time. After all, it is a loss component. Don't expect your buddies to expect battery life = original life!
