What are the main factors that affect the life of a notebook?

for some just buy notebook computer users, very care about the laptop battery utilization rate, whether it can be full of electricity charging use, whether need to use battery recharge, how to ensure battery life?

Too long not to look at the version

Lithium batteries do not need to use no electricity to recharge.

The first few charges do not need to charge 12 hours. Charging is full, even if the charge line does not pull and no charging current.

Users who often use batteries do not need to worry about plugging in electricity. But pay attention to the temperature.

For users who are basically not using batteries, they can occasionally unplug the power from the battery.

The answer to this question is to see how it affects the life and capacity of the lithium, and how the current electronic devices "treat" the battery.

What affects the life of the battery

Undervoltage, Overvoltage, overcurrent, storage passivation, high and low temperature, charge and discharge aging are the important factors that affect battery life.

and charge-discharge aging is mainly in depth and high current charging problem, so in fact is not so extreme under pressure, over pressure, over current. It is only in the factory calibration of the threshold within or outside the problem. At present, lithium battery manufacturers for these parameters of the balance is generally to ensure that 300 times after the deep charge and discharge cycle of residual 60-80% capacity as the bottom line, to achieve this bottom line, the general is not inclined to pursue a higher life expectancy, but instead to pursue capacity and current. This is also consistent with the charging frequency of mainstream electronic products and the life cycle of the product itself.

Chip charging voltage and current curve, the horizontal axis is divided into three regions, respectively, "trickle pre-charging", "constant current charge", "constant voltage charging" these three stages

The use of users, regardless of the use of good or bad, in the usual situation, will not cause a particularly significant lithium battery damage, taking into account the current frequency of electronic equipment updates, in fact, happy to use it. If you don't think about using it well, you need to protect the battery. Next, there will be several common statements (pì) (Yáo) ...

Saying one

Do you need to recharge it without a power shutdown?

On the mobile phone, notebook battery use of the most widely circulated a saying, "must be used without electricity shutdown and recharge," said the professional one is to perform a deep discharge every time. This argument in the Ni-MH battery era, due to the existence of memory effect, is reasonable. But in the lithium era, it is best not to do so deliberately, the principle is also seen before, in fact, deep discharge and over put to Undervoltage does not have an obvious strict boundary. Long-term deep and shallow, the maximum may have several times the life difference. Of course, also do not need to use the battery when not dare to use, after all, the manufacturer's protection will not let your battery seriously damaged. All in all, the advice for when to start charging is to recharge it when it's convenient to recharge.

Say two

12 hours before the first few charges?

Many places have a computer phone to buy back, a few times before charging must be enough to charge 12-24 hours of the argument. Because of the existence of a battery-charging chip, there will be no charging current after full power. The living can not be tethered to the line, it is time to pull away, full of May pull, not full also can pull.

Saying three

Do not fill the notebook with electricity and plug it in?

Many people think 100% full power is "overcharge". I don't think that's right. Shallow charge (charge not full) although also will have a slight benefit to the life, but the relative trouble and the capacity loss, this advantage is not worth. The real problem with 100% full electrical wiring is "storage passivation", especially when the storage passivation is full. However, for users who have at least one battery charge or discharge per week, the problem is largely without concern. However, if the perennial plug-in full power use, it does produce passivation phenomenon. At the same time, high temperature will greatly accelerate the passivation and aging process.

Therefore, for users who often use a battery, the suggestion is, so use it, passivation will not be too obvious. But do not put on the quilt, pillow and so on will block the heat sink the thing to use, also do not perennial in hot dead place use.

Saying four

Long-term plug-in does not use the battery harmful?

For users who rarely use batteries, passivation is a real problem. There are some solutions, such as not to fill and remove the storage, but the practicality of the problem.

For not filling this method, because the notebook computer generally does not provide plug in the power and not full of functions, then means that users need to unplug the power when not full, with a period of time before inserting, so repeated. In this way, you will often forget to plug and turn into a deep charge. The main thing is that we are users are not slaves ah, tired not tired ah!

For the way to remove the storage, first do not full of electricity storage, otherwise it will be the same as installed on the machine. But the electricity also must not be too low, mentioned previously, the battery has self-discharge. Low battery storage is very easy because of self-discharge caused by undervoltage, so the damage to the battery is very large. In this case, the direct large current charge of the battery will further damage, so the control chip will use a very low current charge to a certain voltage, and then into a constant current charge. In order to avoid self-discharge, but also because even if the electricity storage will still produce passivation (just slow), we need to take out regularly to do a number of charge and discharge cycle, activate the passivation of the electrodes, while filling in for the next storage cycle of the required electricity. Tired not tired Ah! Moreover, the notebook computer buys, still may have occasionally go out to use, if not just to catch up just once activated, then you take out is a only half of the electricity, and passivation can not put out so many also not charge into the battery. If you don't go out for 100%, then you care about the battery.

So, for the basic battery-free users, my advice is, occasionally unplug the power to use the battery.
