Laptop battery wear and tear problem urgently

Laptop batteries are often undercharged or even damaged after a long period of use, so you must pay attention to some tips when using: whether your laptop uses lithium or nickel-metal hydride, try to use up the power as much as possible and then recharge it (less than 5%), which is the best way to avoid the memory effect. In fact, lithium-ion batteries also have a certain memory effect, but they are much smaller than nickel-metal hydride batteries.

However, it should be noted that when charging, try to avoid too long time, generally within 12 hours.

The length of a battery's life is not determined by the total time it has been used, but by the number of times it has been charged and discharged. If you always attach the battery to the laptop without removing it, the battery will not remain fully charged as you would think, even after turning off the machine and removing the AC power. Laptop batteries consume power even when the computer is powered off due to the control circuitry integrated into the battery.

As soon as it is connected to the AC power supply, the battery will start charging, and whenever the power is turned on or off, the battery will be charged and discharged repeatedly, affecting the battery life.

It is best to unplug the battery when using the AC external power supply, otherwise the battery will be in a hot state for a long time, which will affect its lifespan. If the battery is not used for a long time, please flush and discharge it at least once every two months to ensure its activity. There is also an issue that needs to be taken care of when storing batteries.

At present, the lithium-ion batteries used in the vast majority of notebooks are often prone to over-discharge if they are not used for a long time, and may no longer be able to be charged. To prevent over-discharge, it can be kept in a cool, dry place in a half-charged state, and then charged to half a year again.

In addition, factors that affect battery life include the temperature of the use environment (it is recommended to use it below 30), the storage temperature of the battery, and the vibration of the battery. The battery will age after being used for a period of time, and the specific performance is that the internal resistance becomes larger, and the voltage at both ends rises relatively quickly when charging, so that it is easy to be judged by the charging control line to be full, and the capacity is naturally reduced. Battery correction is an effective way to deal with aging batteries, and a few notebooks will have dedicated battery correction software.

If your laptop doesn't have dedicated discharge software, then you can follow the steps below:

Disable screen saver;

Set the power usage scheme to "Always On" in Windows Power Management;

In the Alerts tab, set the Low Battery Alarm to 10% and the action to No Action;

Set the "Critical Power Shortage Alert" to 3% and the action to "Waiting";

Adjust the brightness of the screen to the maximum;

Confirm that all windows are closed and that all previously worked data is saved;

After confirming that the battery is charged at more than 80%, unplug the power supply and all external devices.

After the discharge is over, the notebook will automatically shut down, and then plug in the power supply to let the notebook charge, this process can be repeated 2 or 3 times, the purpose is to let the battery continue to discharge at a small current, and this discharge state is impossible to achieve in our daily use, and the effect is basically the same as those dedicated discharge software.

The battery cannot be repaired, as long as you use it there will be a certain amount of loss, if your battery is fully charged, and connected to the adapter, it will be better to remove the battery at this time.

It's normal to use Master Lu's test, because that's wrong! Hey, hey......There are related articles on the Internet. This is a loophole for Master Lu. You try again with everest, it should be 0%.

The battery of the notebook is a consumable, and the life of the ta is not as long as the user imagined, and its loss rate is generally related to the user's notebook usage habits. For example, when the laptop is fully charged, unplug the socket and use the battery, play games when using the battery, turn on the power supply brightness to the maximum, and a series of usage habits will accelerate the consumption of its life.

Read below to find out what causes laptop battery drain.

One: Common causes of laptop battery loss:

1. The socks are often charged and discharged;

2. Use inferior chargers;

3. Long-term operation in high temperature environment;

4. The battery is connected to high-load peripherals, and the plugging and unplugging is not standardized;

5. Transition charge and discharge, now the circuit is protected, but it happens occasionally.

2. Laptop battery wear and tear due to bad usage habits:

1. Put it on some hot bad conductor state good traces to use a notebook (such as a bed towel, pillow);

2. Put it in the bag before it is completely turned off, and the notebook continues to work and heats up, but the heat cannot be discharged in the bag;

3. The degree of loss is related to the contact medium, whether it is close to the battery part, and the heat situation, but it is undeniable that the probability of abnormal loss of the battery caused by this behavior is quite high, and this use is also one of everyone's habits.

Three: laptop battery wear and tear maintenance misunderstandings:

1. When using the battery for the first time, it needs to be charged for 12 hours for the first three times;

2. In order to prevent the memory effect, it is necessary to use up the electricity before charging;

3. When plugging in AC power, take the battery off to prevent repeated charging and discharging.

Although repeated charging and discharging will cause the loss of the laptop battery, this process is not avoidable, users do not have to over-book and worry about the loss of the laptop battery, the best way to avoid excessive wear and tear of the laptop battery is to develop good habits.

Laptops' lithium-ion batteries all have a design capacity, and this capacity value is the theoretical value of the maximum capacity of the battery. As the battery is used, the maximum value of the actual capacity will gradually decrease, and this part of the reduced capacity is the loss of the battery.

For example, the theoretical capacity of a laptop battery is 5000mAh, and after a period of use, the actual maximum capacity has become 4600mAh, so the battery loss is (5000-4600) 5000 100%=8%.

Battery loss at 0-10% will not affect normal use. If the loss is too large, the battery life will be very weak, and it can only be plugged in.
