01. Appropriate use and storage environment Whether it is lithium or nickel, there are strict requirements on the temperature and humidity of the storage environment. Among all environmental factors, temperature has the greatest impact on battery charge and discharge. The electrochemical reaction inside the lithium battery is related to the ambient temperature. If the temperature is too low, the battery will have no voltage output, which will result in failure to start. If the temperature is too high, the self-discharge rate of the battery will increase, which is not conducive to long-term storage. Tips: The operating temperature range of mobile phone lithium battery is: -20 °C-60 °C, the general mobile phone battery is limited to 40 °C, but it should be noted that the charging and discharging temperature should not be placed below -10 °C and above 45 °C, charging The efficiency will drop and it will lead to dangerous situations such as battery leakage. 

Short-term storage: store the battery in a dry, non-corrosive atmosphere, Where the wet temperature is between -20 ° C and 35 ° C, the temperature is high or low, causing the battery metal parts to rust or the battery to leak. Long-term storage: Since long-term storage will cause battery activity passivation, the self-discharge speed will increase, and the ambient temperature is preferably between 10 ° C and 30 ° C. In addition, a charge and discharge cycle is required every 3 months to maintain its activity and Restore performance. 

02. The correct way to use the battery is a consumable, and It has a certain life span, and the number of charge and discharge is usually 300-500 times. Therefore, mastering the correct method of use is the secret to let the battery "longevity". Usually, the lithium battery has a relatively complete protection board, so there is no big problem or limitation in charging, but in order to prevent the safety problem caused by the failure of the overcharge protection function, it is not recommended to charge for a long time, and immediately remove the battery when it is full. Is the most correct approach. In addition, it is best to use the original charger and charging cable, because this is the most reliable charging method for the current device, and the most safe and efficient charging method. 

In the extremely cold weather, try to avoid the outdoor battery. The self-discharge rate of the battery is slow in the environment where the temperature is too low. After a long time, the battery will not be able to be turned on, and the battery capacity will be reduced. In addition, do not put the battery in a humid environment, or mix it with other conductors, which may cause the battery to be short-circuited and the battery may not be used. The above is the answer, follow the above tips to save, maybe you can make a spare battery afterwards.
