The life of lithium battery of notebook computer is limited, so it can't be charged after 300 ~ 500 times.
Matters needing attention in lithium battery charging are as follows:
Avoid charging at too high a temperature.
If the lithium battery is used in an environment higher than the specified working temperature, that is, above 35℃, the power of the battery will continue to decrease, that is, the power supply time of the battery will not be as long as usual. If the equipment is charged at this temperature, the damage to the battery will be even greater. Even if the battery is stored in a high temperature environment, it will inevitably damage the quality of the battery. Therefore, it is a good way to prolong the life of lithium battery to keep the appropriate working temperature as much as possible.
Avoid charging at too low a temperature.
If the lithium battery is used in a low temperature environment, that is, below 4℃, it will also be found that the service time of the battery is reduced, and some original lithium batteries of mobile phones can not even be charged in a low temperature environment. But don't worry too much, this is only a temporary situation, which is different from the use in high temperature environment. Once the temperature rises, the molecules in the battery are heated and will immediately return to their previous charges.
