Winter is the season when most people do battery storage. Because many people use LiFePO4 batteries as camping batteries, they will not be of much use in winter. During winter, the temperature is relatively low, and in some areas it may reach -20°C. Since the battery is actually a chemical reaction, in winter, the self-discharge rate of the battery will be relatively low, about 2~3% per month. However, it should be noted that when storing batteries in winter, it is best to ensure that the battery storage temperature is higher than room temperature, especially in an environment of -20°C. Too low temperature is not a good thing for batteries. Again, it should be stored indoors. More information can be found in: LiFePO4 Battery Winterize.
