In accordance with IEC, the cell should be stored under temperature 20℃±5℃ and humidity （65±20）%. Commonly temperature is higher, while capacity retention is lower, and vice versa. The best place to store a cell is in a refrigerator with a temperature range of 0℃-10℃, especially for primary batteries. While for secondary batteries, their loss of capacity during storage, may be better compensated by recharging.
