Lithium battery life is generally 300-500 charge cycles. Assuming that the power provided by a full discharge is 1Q, if the reduction of the power after each charging cycle is not considered, the lithium battery can provide or supplement 300Q-500Q of power in its life. It is known that if you charge with 1\/2 each time, you can charge 600-1000 times; If you use 1\/3 of the charge each time, you can charge 900-1500 times. In the same way, if the charge is random, the number of times varies. In short, no matter how it is charged, the total amount of power added to 300Q-500Q is constant.
Avoid charging at excessively high temperatures
If lithium is used in an environment above the specified operating temperature, that is, 35°C, the battery's power will continue to decrease, that is, the battery's power supply time will not be as long as usual. If you charge the device at such a temperature, the damage to the battery will be greater. Even if the battery is stored in a hot environment, it will inevitably cause damage to the quality of the battery. Therefore, trying to maintain a suitable operating temperature is a good way to extend the life of lithium batteries.
Avoid charging at too low a temperature
If lithium is used in a low temperature environment, that is, below 4°C, it will also be found that the use time of the battery is reduced, and the original lithium battery of some mobile phones can not even be charged in a low temperature environment. But don't worry too much, this is only a temporary situation, unlike the use of high temperature environment, once the temperature rises, the molecules in the battery are heated, and immediately return to the previous charge.
often use
Life lies in movement. In order to maximize the performance of lithium-ion batteries, it is necessary to use it frequently, so that the electrons in the lithium battery are always in a state of flow. If you do not often use lithium, please remember to complete a charging cycle for lithium every month, and do a power calibration, that is, a deep charge
