Freezing can restore the ionic performance of the lithium battery. Normal temperature favors ionic performance. Lithium batteries can generally be charged and discharged 300 to 500 times.
It is better to partially discharge lithium batteries than to fully discharge them, and try to avoid frequent full discharges.
Once the battery leaves the production line, time begins to tick.
Whether you use it or not, the lifespan of lithium batteries is only two to three years.
The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main cause of the decrease in battery capacity).
Eventually, the cell's resistance reaches a critical point and, although the battery is fully charged, it is unable to release the stored energy.
The aging rate of lithium batteries is determined by temperature and state of charge.
The data below illustrates the reduction in battery capacity for both settings.
Load temperature 40% (recommended) Load 100%
00°C 98% 94% after one year 96% after one year
25°C 96 % 80% after one year After one year
40°C 85% After one year 65% After one year
60°C 75% After one year 60% After three months< /p>

As the above shows, high state of charge and increased temperature accelerate the decline in battery capacity.
