Regarding the use and maintenance of laptop batteries, I believe many friends are not sure what is the best. Today, we will do a science popularization.
1. Can the laptop be used while charging?
Lithium batteries in notebook computers have no memory effect. Lithium batteries produced by regular manufacturers have a relatively complete BMS to control overcharge and overdischarge.
In fact, when playing games and running large programs, in order to maximize the performance of the processor, graphics card, and memory, it is actually necessary to plug in the power source, and it will not cause damage to the battery.
2. Can the laptop be connected to the power supply all the time?
In fact, it is better not in theory!
After the laptop is powered on, the battery does not supply power and is in an idle state. If the battery is not used for a long time, it will affect the power consumption and life.
It is generally recommended that the battery be charged and discharged at least once a month to allow the battery power to be consumed to about 20%, and then fully charged and cycled once. Do not use automatic shutdown.
However, any product is bought for use, not for enshrinement.
A laptop is also a consumable, and its advantage is that it can be moved around and is easy to move around. It is very convenient whether it is taken to the bed, to the cafe, to the meeting, or to the class.
3. Can the laptop be charged all the time without unplugging the power supply?
Most of them are okay because of the existence of charging protection, similar to mobile phones.
However, theoretically, the problem of "storage passivation" may still occur, that is, the charging display is full, but the voltage drops rapidly during use, and the capacity of the battery decreases compared with the normal state.
Therefore, it is recommended to unplug the power occasionally and use the battery to keep the lithium battery active and prolong its service life.
4. Other maintenance knowledge of laptop battery
－ The laptops are now lithium batteries, you can use them directly after you buy them, and you don’t need to charge and discharge them completely.
－ It is generally recommended to put the battery directly in the computer for normal use, without removing the battery for storage.
-When using the battery alone, try not to use it up completely, and charge it at least 15%.
-If you need to store the battery, you must ensure that there is enough power in it. Empty storage can easily damage the battery.
