How to charge a laptop battery and how to use it

1. Activate the new battery.

When a new laptop battery is first turned on, the battery itself should have more than 70 charges (this is also a common practice for manufacturers). If you open the laptop you bought for the first time and find that the battery is fully charged or more than 70% charged, it means that the manufacturer has done a factory test). At this time, you should fully charge the battery, the charging time must be more than 12 hours, and then set the battery to turn off when the battery is 5% power, and repeat it three times, so that the battery can be completely activated, which can effectively improve the service life of the battery.

2. Reduce the number of battery uses.

Try to minimize the number of times you use the battery, this method feels a little unpleasant, since you buy the battery and don't let it be used often, then buy it to do nothing. Having said that, the number of times a battery is charged and discharged is directly related to its lifespan, and with each charge, the battery is a step towards aging. It is recommended that you use an external power supply as much as possible, and the battery should be removed when using an external power supply.

Some friends are convenient, often plugging and unplugging the power supply multiple times a day, and the laptop is equipped with a battery, which will cause more damage to the battery. Because each time the external power supply is connected, it is equivalent to charging the battery once, and the life of the battery is naturally shortened.

3. Avoid charging for a long time.

Recharging after running out of power and avoiding charging for too long, whether your laptop uses lithium or nickel-metal hydride batteries, be sure to run out of power and recharge (less than 1 battery), this is the best way to avoid the memory effect. Regarding the statement that lithium battery has no memory effect, I have already explained that it is an irresponsible misguidance of the merchant. Lithium battery also has a memory effect, but its memory effect is smaller than that of nickel-metal hydride.

The same charging method as the mobile phone battery, when you charge the laptop battery, try to avoid too long time, generally within 12 hours. As for the precautions such as preventing exposure, preventing moisture, preventing chemical liquids, and avoiding contact between battery contacts and metal objects, I will not mention them here.

Fourth, long-term maintenance without batteries.

If the laptop battery is not used for a long time, the battery should be fully charged and discharged once a month to keep the battery alive. In addition, if the laptop battery is not used for a long time (more than annually), it should be charged to about 50% and charged once a year to prevent the battery from over-discharging. It may be better if the power is turned off when charging, but it does not require it to be turned off.

Is it built-in or detachable, just plug it into the charger directly for charging.

It is best not to remove the battery of the notebook, which is generally installed automatically when you buy a computer, and you don't need to install it yourself.

When you usually use it, you can connect it directly to the power supply, it will automatically charge, until it is fully charged, do not pull out the power cord after charging, and let it be powered all the time. The battery alone is generally powered for 2 to 3 hours, of course, the longer it is used, the less power supply time it has.

Weigh 12 hours without flushing up so that 3 times the battery is activated.

The battery of the notebook can be used or not, some brothers like to remove the battery, in order to save the frequency of battery use, you can also do this, plug in the power supply and use it normally, usually do not need to install the battery.

The battery is only used to maintain the battery life function, such as in a power outage or when going out. The battery is charged after it is plugged in, and the notebook will have a light prompt, so you can take a closer look for yourself. Generally, the power supply is two hours to two and a half hours, depending on your usage, if you open the game, the sound is still loud, and the power consumption is naturally fast.

1. On the first charge, you should charge the battery continuously for 12 hours, and cycle the full charge and discharge 3 times to fully wake up the new battery.

2. If you use the external power supply for a long time, it is best to remove the battery. Many friends don't notice this problem, not removing the battery when using an external power supply not only affects the battery life, but also makes the heat dissipation burden of the laptop heavier, shortening the life of the laptop.

3. Charge and discharge regularly。Even if lithium-ion batteries without memory effects have a certain inert effect, they will be inactive if they are not used for a long time and need to be reactivated. Therefore, if you do not use the computer for a long time (3 weeks or more) or find that the battery charge and discharge time becomes shorter, you should make the battery fully discharged and then recharge, generally at least once a month.

4. It is best to turn off the laptop when charging, so that the battery can be fully chargedDo not unplug in the middle of charging. Charging off will shorten the charging time by more than 30% compared with charging on power, and can extend the life of the battery. It is best to use it 30 minutes after charging.

5. Prevent exposure to the sun, prevent moisture, prevent chemical liquid erosion, and avoid short circuit between battery contacts and metal objects. The number of charging and discharging of lithium batteries generally does not exceed 800 times, and each time it is charged, it shortens the life of one time.

Precautions related to computer charging

1. Use the original charger to charge the laptop.

2. When the laptop is charging, don't touch it with wet hands.

3. Don't deliberately charge the laptop after it runs out, this is not good for the battery, and the computer can be charged when the battery is about 8.

4. Don't overcharge the laptop battery, and then recharge it when you have time.

1. When charging the laptop for the first time, you must remember to charge and discharge the laptop battery three times, that is, when you use the laptop for the first time, you must fully charge the computer battery three times, and then discharge it.

2. In order to better activate the chemicals inside the laptop battery, in the process of using the laptop, it is best to carry out a complete discharge work once a month, so that the chemicals inside the battery can be better activated, so that when we use the computer, the state of the battery can be guaranteed to be the best, and this can also better stimulate the activation performance of the laptop battery, which can increase the service life of the laptop to a certain extent.

3. If the laptop's battery has been left for a long time, we still need to treat it like a new battery, and we need to reactivate the laptop battery.

4. If the battery of the laptop is a nickel-metal hydride battery, it needs to be reasonably controlled for its charging time, and it cannot be charged frequently, otherwise the service life of the laptop battery will be reduced. When using a laptop, it is necessary to charge and discharge it at least once a month, and the battery is charged and discharged, which is beneficial to the laptop battery.

5. Lithium electronic battery has a great inert effect, if the laptop battery is not used for a long time, its activity will slowly disappear, so every time it is used, it needs to be reactivated, and the laptop is in an alternating current environment, try to remove the battery, so that the laptop will not be in a charging state for a long time.

6. In the process of charging the laptop battery, try not to use the laptop, and do not unplug the power supply during the charging process, after completing the charging, wait for 30 minutes before starting to use the laptop.

<>How to properly charge your laptop battery

Try to avoid waiting for the battery to run out of power before charging, as this can put a lot of stress on the battery and cause damage. It is more feasible to charge when there is about 20-30% of the battery remaining. In fact, there is a limit to the number of times a notebook's lithium battery can be "recharged", and recharging it all will only greatly shorten the battery life.

At the same time, the battery should be charged in a relatively dry place, and it is also necessary to pay attention to the heat problem, which is the enemy of the battery.

Tips: The use of mobile phone batteries is not the same as the use of laptop batteries, and many people may judge based on their own experience in using mobile phone batteries, and feel that laptop batteries should be used up and recharged, which is not right.

How to store laptop batteries that are not in use for a long time

Should laptop batteries be stored with photoelectric or should they be stored fully charged? Long-term storage of discharge photoelectric will make the battery cell inactive, and even lead to the control circuit protection self-locking and can no longer be used, long-term storage of full charge will bring safety hazards, the most ideal storage method is to use the power to about 40% and then store it in a cool and dry place'Place, about 20 degrees Celsius is the ideal storage temperature. Of course, it is best to take out the battery once a month to use it, which can not only ensure the good preservation state of the battery, but also prevent the battery from being completely lost and damaged.

A few measures to extend the working time of your laptop battery

1> Lower the brightness of the screen: You can use the fn down and up key combination to quickly adjust the brightness (the specific fn + which key needs to look at the respective notebook).

2> Make good use of standby, sleep and other functions: When the computer is not used for a long time, the laptop can be used to standby or sleep, which not only saves power but also prolongs the service life of the computer.

3> Turn on the CPU SpeedStep function, which can greatly extend the working time of the battery: The CPU's SpeedStep function is started by default in the BIOS, and when the battery is used, the CPU will be automatically downclocked to achieve the purpose of energy saving. If it is not enabled, you can press F2 to enter the BIOS to find Performance and set SpeedStep Enable to Enabled.

4> When using the battery, try to turn off the wireless, Bluetooth and infrared ports. At the same time, remove unused peripherals and avoid enabling large 3D programs, games, etc., to reduce unnecessary battery consumption.

Problem description: I bought a new Tsinghua Tongfang notebook, and I don't know how to charge the battery better.

The battery seems to be a lithium battery, when I bought it, the installer pressed the battery, plugged in the power supply, and then installed the system, I didn't charge it after I came back, and directly used the battery to shut down, and then charged for 12 hours, but it was only about 2 hours before it ran out of power (it was turned off when charging, and it was good to charge it on or off it?). )

How should I charge and use it next?

I've seen the same problem on the Internet, I don't know what it is, please don't copy it in large sections, I hope friends who have used laptop batteries talk about some experience. Thank you.

Analysis: I used the same brand as you, I asked his after-sales service, and what I got was this:

1.The new battery should be charged and discharged thoroughly. There is no need to charge for 12 hours, because it will not be charged after a full charge.

2.Both off-power charging and power-on charging are OK.

3.Remove the battery when using an external power source.

Basically, that's it.,After all, we're using a notebook.,Not a notebook with us.,Don't bother so much.,If there's an external power supply, you don't need a battery.,If the battery needs to be used more.,Sooner or later it's going to be scrapped.。

In addition, you can also ask about their after-sales service yourself.
