How to maintain laptop battery
1. If the external power supply is used for a long time, it is better to remove the battery. Many friends have not paid attention to this problem. If you do not remove the battery when using the external power supply, it will not only affect the battery life, but also make the cooling burden of the laptop become heavier and shorten the life of the notebook computer;
2. When charging for the first time, you should charge the battery continuously for 12 hours, and fully charge and discharge the battery three times to fully wake up the new battery;
3. It is better to turn off the laptop when charging, so that the battery can be fully charged. Do not unplug the power supply in the middle of charging. Switching off charging can shorten the charging time by more than 30% and prolong the service life of the battery. It is better to use it after 30 minutes of charging.
4. It can prevent exposure to the sun, damp, chemical liquid erosion and short circuit between battery contact and metal. Generally, the charge and discharge times of lithium battery are no more than 800 times. Each time the battery is charged, its life is shortened once.
5. Charge and discharge regularly. Even if the lithium-ion battery without memory effect has certain inert effect, it will lose its activity if it is not used for a long time and needs to be reactivated. Therefore, if you do not use the computer for a long time (3 weeks or more) or find that the battery charging and discharging time becomes shorter, the battery should be fully discharged before charging and discharging, generally at least once a month.
For notebook battery maintenance, we must pay attention to the above points. The validity period of notebook battery is 2 years. If it is expired, it will easily lead to aging.
How long can a laptop battery last
Notebook battery is the main part of the notebook, if the battery maintenance, it can also extend the life of the notebook. Generally speaking, how long can a laptop battery last?
There is no time limit concept. The service life of an 8-cell lithium-ion battery (remember, it's the service life) is about 800-1200 times of charging. There must be problems with the quality of batteries below this number.
How to fundamentally extend the life of the battery (that is, life), there is no need to take the battery off the laptop! I have a good idea. You can try it. If you have AC power around you, connect the AC power to your laptop before you turn it on every day. Make sure the battery light is on before you turn it on! Remember! In this way, our battery is charged with some micro current, and the power protection of the motherboard will not let the machine have any problems! In this case, the battery does not count the number of charges!
The service life of notebook battery is generally 2 years. If the battery is still in use after 2 years, the mobility of notebook will be affected due to the decrease of standby time, and even the service life of notebook will be affected.
How to use notebook battery
Notebook battery belongs to lithium battery, and when the notebook battery is full, it can be used for about 2 hours, so the notebook battery needs to be charged frequently. How to use the notebook battery?
1. Try to reduce the number of times to use the battery. You should know that the number of battery charging and discharging is directly related to its service life. Every time the battery is charged, the battery will be retired. It is recommended that you use the external power supply as much as possible, and the battery should be removed when using the external power supply. Some friends map convenient, often in a day many times plug in and out of the power supply, and laptop with battery, do so, more damage to the battery. Because each time the external power supply is equivalent to charging the battery, the battery will naturally lose its life.
2. Activation of new batteries to make your notebook battery longevity, must have a good start, this has to start from the purchase of notebook. When a new laptop is turned on for the first time, the battery should carry 3% of the power (which is also a common practice of manufacturers). At this time, you should not use the external power supply, use up the remaining power in the battery until it is shut down, and then use the external power supply for charging. When you go home, you have to charge the battery after it is used up. The charging time must be more than 12 hours. Do it three times repeatedly in order to activate the battery, so as to lay a good foundation for future use.
3. Recharging after running out of power and avoiding long charging time. Whether your notebook uses lithium battery or nickel hydrogen battery, it is the best way to avoid memory effect by recharging after running out of power (less than 1%). Lithium battery also has memory effect, but its memory effect is smaller than that of Ni MH. The charging method is the same as that of the mobile phone battery. When you charge the notebook battery, try to avoid too long time, which is generally controlled within 12 hours. As for the prevention of exposure to the sun, to prevent moisture, to prevent chemical liquid erosion, to avoid contact between battery contacts and metal objects.
Only the correct use of notebook battery, in order to extend its service life, to avoid damage to the notebook.
