1. Prevent charging at excessively high temperatures.
If lithium batteries are used in environments exceeding the specified operating temperature (above 35°C), the battery capacity will continuously decrease, meaning the battery's operating time will not be as long as usual. Charging devices at such temperatures will cause even greater damage to the battery. Even storing batteries in warm environments will inevitably cause some damage to their quality. Therefore, maintaining a suitable operating temperature is a good way to extend the lifespan of lithium batteries.
2. Prevent charging at excessively low temperatures.
If you use a lithium battery in a low-temperature environment, i.e., below 4C, you will also find that the battery life is reduced, and some original lithium batteries in mobile phones may not even charge in low-temperature environments. But don't worry too much, this is only a temporary situation. Unlike the use in high-temperature environments, once the temperature rises, the molecules in the battery are heated and immediately recover their previous capacity.
3. Frequent use
Life is about movement. To maximize the performance of a lithium-ion battery, use it frequently to keep the electrons inside constantly flowing. If you don't use your lithium battery often, remember to complete a full charging cycle each month and perform a charge calibration, i.e., a deep discharge followed by a deep charge.
