Notebook battery use precautions, how to use laptop batteries is correct

1. Recharge after use, and the new machine purchased should be charged for more than 3 consecutive 12 hours to prevent the "memory effect".

2. There is no harm to the battery without unplugging the battery while connecting the DC power supply, because the battery will not accept any power injection after it is fully charged, and all the power will be directly transferred to the power supply system of the notebook. But when the laptop is running at high speeds and the inside is overheating, it is better to remove the battery, otherwise it will be harmful.

3. Long-term storage of photoelectric discharge will make the battery cell inactive, and even lead to the self-locking of the control circuit and can no longer be used, long-term storage with full charge will bring hidden dangers to safety, the most ideal preservation method is to use the power to about 40% and then store it in a cool and dry 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.

4. Try to avoid waiting for the battery to run out of power before charging, because this will put a lot of pressure 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.

This is definitely the best.

1. The remaining 10% 15% can be charged, if you use it to 0% charging, the battery will be quickly lost;

2. It's okay to charge 100% for the first time, it's useless to continue charging, and when it reaches 100%, the laptop won't charge the battery;

3. Refer to Article 2 for the second and third charges, these charging methods you said are not applicable to laptop batteries;

4. When there is an external power supply, you can not take off the battery, it is very simple, as long as the battery is 100% full, it will not charge the battery when connected to the power supply, and it is okay to take it off, it can be turned on anyway.

5. The question you asked later is too cumbersome, I will tell you clearly at one time, if you want to save the battery for a long time and minimize the loss rate of the battery (the battery will be lost every time you charge and discharge), you must use (discharge) the battery to 40% of the power after it is fully charged, and then remove the battery to save. During the placement, the battery will still leak some power, which is normal and don't worry.

And once a month, the battery should be installed and used (used to the remaining 10 15%), then charged to 100%, and then discharged to 40%, and then removed to save the battery. This is done to keep the battery charged.

In the future, if you continue to cycle like this, you will be able to preserve the battery well.

6. If there is still power left in the battery after using the battery, do not charge it immediately, but charge it after using it to 10-15%.

I also use a laptop, generally the first time I use it, the power is all used up and then charged, after the second time, I should try to avoid waiting for the battery to run out of power and then recharge, because this will put a lot of pressure on the battery and cause damage.

Basically, batteries should be charged in a dry place, and attention should be paid to heat, which is the enemy of batteries. Unplugging or not depends on the actual use case: connecting the DC power supply without unplugging the battery does not harm the battery, because the battery will not receive any power injection after it is fully charged, and the power will be directly directed to the laptop's power supply** system.

The life of the battery is fixed, 300-600 times of charge and discharge, generally available for 2 years.

It is more feasible to charge when there is about 20-30% of the battery remaining.

When connecting to an external power supply, try not to use batteries. The battery is fully charged when charging.

After the first three full use of the new computer, when it is fully charged, when it is not in use, the battery is buckled off, and the adapter is used to directly power the computer.

Try to use up the electricity as much as possible, otherwise it will cause great damage to the computer!

If it is generally used in a fixed place, it is recommended to take out the battery and use it directly with a plug-in cable.

But it's best to put the battery on and use it twice a month.

Take off the power supply when using the battery, so that it will not affect the battery life, and then charge it when the battery is exhausted, if the battery is charged, take off the battery when you use the adapter, the quality of the notebook is getting better and better, and you shouldn't have to worry about dust.

If you want to extend the battery life, unplug the battery when plugging it in.

Precautions for battery use:

1. For lithium-ion batteries, no need to activate, just use directly;

2. When there is no external power supply, if the card in the slot cannot be used temporarily in the working state at that time, it is recommended to remove the card first to prolong the battery life.

3. Avoid exposure to the sun for laptops and batteries, and the working environment of batteries and laptops is best at 10-30 degrees;

4. Do not expose the battery to water or other liquids;

5. Please do not unplug the external power supply during the charging process of the battery until it is fully charged; When using a laptop in an environment that provides a stable power supply, it is not correct to remove the battery to prolong battery life.

6. Do not attempt to disassemble or modify the battery, doing so may cause leakage of the battery** or liquid inside the battery, batteries not specified by Lenovo, and batteries that have been disassembled or modified are not covered by the warranty;

7. Do not throw the battery into the buried garbage, and when disposing of the battery, please follow the local laws or regulations;

8. For models with removable batteries: If your computer is not in use for a long time, it is recommended that you unplug the battery and store the battery separately. The battery should be stored at room temperature (10-35 degrees) and charged to 30% to 50%, it is recommended to charge the battery every 1 month or so to prevent over-discharge.

1. If you want to make the laptop battery long-lived, you must have a good start, the battery of the new notebook generally has about 3% of the power when it is turned on for the first time, at this time, do not use the external power supply, use up the residual power in the battery until it is turned off, and then charge it with the external power supply. It is also necessary to recharge the battery after it is exhausted, and the charging time must be about 14 hours, and it must be repeated three times in order to fully activate the battery, so as to lay a good foundation for future use.

2. The life of the battery used in a laptop is measured by the number of times it is charged and discharged. Do not use the battery unless necessary, if the battery is not used for a long time, charge it to about 50 and then store the battery in a cool place.

If the battery is enabled, use it up and then recharge it, and don't plug it in AC power before the battery runs out. When the battery is fully charged, the AC input should be disconnected, as overcharging will overheat the battery and shorten the life of the battery.

3. Generally speaking, today's laptops have intelligent battery protection functions, and the battery will not be damaged by ordinary operations, but it may still be damaged due to the end of its life or other special reasons. For NiMH or NiCd batteries, there is a memory effect, and if used incorrectly, the discharge time of the battery will become shorter and shorter, or even completely unchargeable.

4. When charging the lithium-ion battery, it is first charged quickly in a constant current mode, and then charged slowly in a constant voltage mode after the voltage reaches a certain value. Usually laptops do not have strict constant current charging monitoring devices. When the system load is large, the charging current is small, and vice versa, and this current is determined by the power margin of the AC power adapter.

Obviously, when the system is charging, the battery competes with other components such as CPU, hard disk, LCD, etc. for energy.

5. Discharge is to discharge as little current as possible, the operation is to first let the CPU speed down, the hard disk stops, the screen is darkest (or close and turn off), and then do not run any programs until the laptop automatically shuts down. The reason for the emphasis on low-current discharge is to prevent the laptop from detecting insufficient battery voltage prematurely.

It's very simple, don't take off the battery at any time, install the power-related management software, drivers, etc., and plug it in if you have mains!

…》Charging, first of all, the laptop battery should not be completely discharged, which is extremely damaging to the battery. The first two charging times can be a little longer, and the later can be charged and discharged normally, of course, with the change of use time and charging times, it is normal for the power to gradually decrease, don't pursue the perfection of the data too much, it is useless. Because today's laptops have a complete power management circuit and charging management system, when the battery reaches saturation, the control circuit will automatically switch to the open circuit state, so Xiaoliang only needs to be full, not that the longer you charge, the longer you can use it.

The daily use of the battery, when using the laptop battery in the case of providing a stable power supply, the battery can be removed to delay the service life of the battery, and the number of discharges of the battery is directly related to the lifespan.

Power supply, it is recommended that you use an external power supply as much as possible to minimize the use time and number of times the battery is used. When using batteries, it is also necessary to pay attention to prevent sunlight, moisture, chemical erosion, and contact between battery contacts and metal objects.

Also, when the battery is not in use, you should check whether there is still power in the battery every month (you will slowly grasp the time difference yourself), if the power is very low, it will be fully charged and put it up, and do not put the battery completely dead.
